5 Best Solar Companies in Massachusetts (2025 Reviews)

Why We Chose All Energy Solar

All Energy Solar is the company I’d personally go solar with if I lived in Massachusetts. It installs high-efficiency panels with long warranty coverage to help ensure your above-average electric bills remain covered by your solar production. It also offers an above-average 25-year warranty for workmanship, which helps insulate you from damages and roof leaks occurring due to faulty installation technique.

All Energy Solar also has outstanding customer review ratings, including a 4-star customer review average and an A+ rating with the Better Business Bureau (BBB). In a state like Massachusetts, where solar demand is high and there are nearly 200 installers available, choosing a company based on positive customer reviews is an easy way to find an installer that’s going to provide a good customer experience and is likely to live up to its promises. In fact, All Energy Solar ties for the best rating in our company reputation scoring category in the entire country.

What I Like About All Energy Solar

All Energy Solar has an unmatched reputation for positive customer service and experiences in Massachusetts, which is a big reason why I chose it as the best in the state. Areas with such a high demand for solar, unfortunately, often see companies that deliver poor customer service because many are just in the industry to turn a profit. Positive customer ratings, a history of few complaints and a company history totaling over 15 years all suggest that All Energy Solar is not only here to stay but is equipped to deliver on its promises.

All Energy Solar also scores perfect marks in our ratings when it comes to the standard services and financing options it offers, and it has one of the highest scores in Massachusetts for its add-on services, making it a one-stop shop for converting to solar energy.

What I Don’t Like About All Energy Solar

There’s really not much I can say about All Energy Solar that isn’t positive. If I really had to nitpick, I’d say that it could improve the number of add-on services it provides. It doesn’t offer any energy efficiency upgrades, although I really believe this isn’t a huge deal because the below-average monthly energy consumption and the net metering policy in Massachusetts mean it’s not terribly difficult to offset your electricity consumption entirely and not pay anything for energy each money. Energy efficiency upgrades may actually be overkill in your area.

Additionally, All Energy Solar doesn’t offer company monitoring for installed systems, so you’ll have to keep an eye on production and performance of your system yourself on the monitoring app you get access to. This isn’t a huge deal, but it does require a bit more work on your part, so I do consider it a minor drawback.

All Energy Solar Installation Process and Timeline

All Energy Solar doesn’t include an estimated installation and system activation timeline on its website, but I’d expect the typical 6 to 8 weeks from this provider. The actual process is more or less what you’d expect from any other installer. A representative will first evaluate your property, usually first using satellite images and then via an in-person inspection. The company’s in-house design team will then plan out your system and make sure it fits on your roof and also meets your electricity demands. Once you approve the design, All Energy will pull permits and install the system when the permits are approved. Finally, they’ll coordinate any necessary inspections before activating your system.

All Energy Solar Standard Services & Financing 

25/25

All Energy Solar gets perfect marks in our ratings when it comes to its standard services and financing options. It exclusively uses an in-house installation team, which I recommend in most cases because it cuts down on the risk of miscommunication and unexpected delays that can result from working with multiple companies. All Energy also installs batteries for customers who want them. I don’t recommend them in your area since you have access to solid net metering policies, but if you’re concerned about power outages, batteries are a great option to have.

All Energy Solar also gets maximum points related to its standard services and financing because it offers an app that gives you access to data for your system and consumption, which can help you maximize the impact of your solar array and find issues early, and it also accepts — but, notably, doesn’t push — solar leases and power purchase agreements (PPAs), which help keep solar as affordable and accessible as possible. These financing options aren’t make-or-break factors in Massachusetts for many homeowners due to the below-average installation costs in the area, but with system costs averaging around $24,180 before incentives, they’re still helpful to have.

Cost and Financing Options

All Energy Solar accepts cash purchases, solar loans, leases and PPAs, representing all of the major financing options common in the solar industry.

I recommend you choose a cash purchase, if possible. Although it demands the highest upfront payment, it also helps you avoid interest and rental payments, so it yields the highest long-term savings possible. Cash payments also let you take the federal investment tax credit, an average effective savings of around $7,254 in Massachusetts, based on our research. Paying in cash also leads to immediate panel ownership and raises your property value.

If you can’t make cash work, I’d recommend a solar loan from All Energy Solar. A loan will require that you pay interest, which reduces your all-in savings by around $5,000 over the life of the loan. However, loans make solar far more accessible because you pay a small down payment rather than the entire cost of the system upfront. Loans still let you take the federal credit, and they still improve your property value.

I don’t recommend leases or PPAs because they deliver the lowest lifetime savings of any option — usually between $4,000 and $5,000 — but they’re also the most accessible, so I love when companies include them. In fact, I think the ideal situation is that a company accepts them but is upfront about how much less beneficial they are, as is the case with All Energy. Leases and PPAs don’t lead to panel ownership, so you’ll never see a true breakeven point, you cannot take the federal tax credit and they tend not to add anything to your property value.

All Energy Solar Extra Services Offered 

3/5

All Energy Solar also scores above average when it comes to its additional services available. Most importantly, it handles roof repairs and replacements in-house, which means if you need any kind of roof work done before it’s safe and worthwhile to go solar, All Energy can still serve as a one-stop shop for solar adoption. This is more convenient than having to coordinate with a third-party roofer, and it can also avoid issues with the two separate companies pointing fingers if there’s a problem or a leak.

All Energy also scores points here for installing EV chargers. Massachusetts has adopted EVs more readily than most states and is the 12th most popular state for new EV registrations. That means more customers in Massachusetts will want access to at-home charging, and All Energy will be able to couple EV charger installation with panels and other services. Access to EV chargers is also going to continue to grow in importance in your state, as all new light-duty car sales in Massachusetts must be zero-emission vehicles by 2035. If you’re going to go solar, it’s a wise decision to stay ahead of the curve and couple your panels with an EV charger now.

All Energy Solar lost points in our extra services category because it doesn’t offer any energy efficiency upgrades or company monitoring for panels. The lack of energy efficiency upgrades like smart electrical panels and insulation, window and door installation isn’t a huge deal because the electricity consumption in Massachusetts is well below the national average, so these upgrades wouldn’t go as far as they would in other states anyway. Company monitoring is also a nice option to have to provide long-term peace of mind that your system will continue to function and save you money, but you can do the monitoring yourself, as All Energy provides access to free mobile apps for solar monitoring, depending on the equipment you have installed.

All Energy Solar Environmental Impact & Sustainability Practices 

7.5/10

Going solar is undoubtedly going to reduce your carbon footprint and have a positive impact on the environment as a whole, but that’s not to say that solar panel manufacturing is as clean and renewable of a process as it could be. Making panels still requires pulling resources from the earth and, in most cases, burning fossil fuels to produce the panels. That’s why I like to evaluate each installer based on the panel brands they offer and how sustainable each of those brands is. I look to see if the brands use recycled materials in production, if they have a recycling program to keep their products out of landfills and if they have a history of social, moral or ethical issues, like slave labor, poor working conditions, racism in the workplace and more.

All Energy Solar installs panels made by REC, LONGi and JA Solar. From a sustainability standpoint, I’d recommend REC or JA panels, as these tie with the leaders in the industry in terms of sustainability and environmental impact. REC and JA both use recycled materials during the manufacturing process, have end of life (EoL) recycling programs for used panels and don’t have a history of social or ethical issues in the work place. LONGi scores just a bit lower in terms of sustainability because it doesn’t use recycled materials.

All Energy Solar Equipment Quality & Reliability 

16.85/25

The average cost to go solar in Massachusetts is over $24,000 before any incentives are applied, according to our research, so you’ll want to make sure your system is set up for long-term performance and reliability. To that end, I assess the panel brands each installer offers to see how they stand up relative to other options.

As I mentioned above, All Energy Solar installs REC, LONGi and JA Solar panels. These brands all offer above-average efficiency ratings of 22.5% to 22.6%, which means they’re likely to be able to meet the relatively low electricity demands in the area, despite the below-average number of sunny days the state sees.

Massachusetts sees above-average snowfall, with some areas in the western parts of the state averaging close to 80 inches, more than double the national average. I recommend specifically choosing a solar panel brand with a high snow load rating, which tells you how much snow accumulation your panels can withstand. Of the three brands that All Energy installs, only REC panels have an above-average snow load rating of 7,000 Pascals, making them my top choice for Massachusetts residents.

These two stats are what I believe are the most important to consider in your area, but you can also look at our solar panel reviews for more information.

Warranties and Guarantees

A big part of your system’s longevity and performance over time and in real-world conditions is going to be the warranty coverage you get with your system. I always look at 4 types of warranty coverage when assessing solar providers.

First, I look at equipment warranties. These come from the manufacturer of the panel and not the installer, and they usually cover manufacturer defects for an average of 25 years. Of the 3 brands All Energy installs, only REC offers equipment warranty coverage in line with the industry average. LONGi and JA only offer 12 years of protection, which isn’t ideal.

Second, I look at the performance warranties, which also come from the panel manufacturers. These warranties tell you how much efficiency your panels will maintain as they naturally degrade on your roof. The average coverage is for 25 years and guarantees that between 85% and 92% of the starting efficiency will remain after that period. REC offers the standard 25-year coverage, while LONGi and JA bump that up to 30 years. However, REC panels have a slower degradation and will retain 92% of their efficiency after 25 years, while the other two brands will retain around 89%. This isn’t a huge difference, and the effect on your electric bills will be minimal, especially since the demand for electricity is so low in Massachusetts.

Next, I consider the workmanship warranty, which covers the labor and is especially important in an area like Massachusetts, where leaks and system damage are more likely to occur from a faulty installation due to above-average rainfall and snowfall. All Energy offers a 25-year workmanship warranty, which is outstanding and longer than the industry average of 25 years.

Finally, I look at the roof leak warranty offered by the installer. This tells you how long after the installation the installer will remain responsible for resulting roof leaks. Most companies don’t offer these, and that includes All Energy. The company does lose points because of this in our ratings, especially because the above-average precipitation in Massachusetts makes roof leaks more of a concern in the first place.

All Energy Solar Company Reputation 

22.5/25

All Energy Solar has a stellar reputation in the local solar industry, and its above-average customer review ratings play a big role in why I chose it as the best solar company in Massachusetts. First off, the company has been serving customers since 2009, so it has 15 years of experience. In a high-demand area like the Bay State, experience says a lot about a company’s ability to maintain a level of success and persist in the fast-paced industry. I’ve seen lots of companies come and go in the state, and those that only have a few years of experience are less likely to stick around and keep your warranty coverage — specifically your workmanship warranty — intact.

The company also has an outstanding 4-star customer rating with the BBB, which is well above what most other providers have. This suggests high-quality customer service and, as I’ll explain a little later, a willingness to stand behind its products and services and carry out repairs that are covered by its warranties.

All Energy Solar has installers on its team that are certified by the North American Board of Certified Energy Practitioners (NABCEP®), which means they have extra training to help ensure your installation process is smooth and everything is up to code the first time around.

On the other hand, it’s not a member of the Solar Energy Industries Association (SEIA). Membership suggests that a company is financially invested in the industry, which I would like to see, but I don’t feel this is a make-or-break factor.

Consumer Reviews and Testimonials

The biggest takeaway from my review of the company’s reputation is that customer reviews are overwhelmingly positive. When customers complain about deceptive marketing practices or a lack of responses to warranty claims, it suggests that the company may not be the best option. Thankfully, most All Energy Solar reviews don’t mention these issues. Positive reviews comment on the company’s great customer service, fast response times and ability to meet customer expectations, as well as its standing behind its warranty promises. Negative reviews mention high costs to remove and replace panels if there are problems, and some mention that the energy production expectations weren’t met, resulting in reduced savings.

I’ll include one positive and one negative review below that I believe illustrate the best- and worst-case scenario you could reasonably expect when going solar with All Energy.

“My home’s 25 panel solar [system] was installed in 2018 and works just fine. All my contacts with All Energy Solar have been positive, and all employees that I’ve met have been outstanding. I also installed a Tesla Power Wall two years ago for the home’s backup. I’ve been so impressed with how it works that I am now in the process of adding both a second Power Wall and an EV 60-amp charging circuit to my home all being done by All Energy Solar. My son has also used this company with solar on his home too.” — John H. via BBB

“During [the] installation of our solar panels 10 years ago, we were very pleased with the service. Recently we had a roof leak on the portion that the panels were located. We called All Energy Solar to have the panels removed so that repairs could be done. After over a month of calling and speaking to at least 8 different people, the panels were removed at the cost of $3,600 for an hour and three quarters of work by three people. When we discussed the reinstallation of the panels on our garage roof (an easier location) the All Energy Solar contact stated the cost would be $18,000, a ridiculously high price for the 14 panels (which we own).” — Eugene P. via BBB

All Energy Solar Customer Service 

10/10

The final score we assign to each solar provider is for general customer service. I come up with this score based on my experience as a secret shopper, and also based on the dozens of reviews I read through.

When I called All Energy Solar, the representative was helpful and honest, and they meticulously explained why they recommend a cash purchase or loan, as well as how it would benefit me more. I love hearing this from installers, as it shows they have the customer’s best interest at heart.

I also read through reviews on the BBB and Google Reviews to get a sense of the overall customer service and experience, and, while there are some issues with customers facing problems with maintenance and repairs, most customers are totally satisfied with the installation and the company’s commitment to its services beyond that point.

Why We Chose Momentum Solar

Momentum Solar is a great option for Massachusetts homeowners looking for high-quality customer service. Momentum offers a concierge service, which means you’ll always have a single point of contact throughout the entire process. When I went solar with a local company, I found it a bit confusing when it came to the person I should be reaching out to at different parts of the process. This isn’t a huge deal, but I do think a set-up like Momentum’s would have been more convenient and may have avoided some minor delays in the process.

Momentum’s customer-centric service also means that your representative will take care of filing for permits, which is typical, but what’s not always guaranteed is getting help searching for and filing for solar incentives, which Momentum offers at no additional charge. Your rep will help you navigate the Massachusetts solar incentives to get the best deal possible on your solar array and maximize your long-term savings.

Momentum also makes going solar easy and stress-free by creating a one-stop shop for conversion. They’ll take care of permitting, inspections, roof repair, tree trimming and more, which means you won’t have to spend time finding and vetting multiple professionals to tackle your installation.

What I Like About Momentum Solar

Momentum Solar is the solar company I’d choose in Massachusetts if you’re looking for a simplified installation. It scores maximum points when it comes to the standard solar services offered, plus it covers auxiliary projects, like roof work and tree trimming to prepare your property for solar.

Momentum also works with all tier-one panel brands, which is uncommon. Most installers just install 1 or 2 brands, which means you don’t have much room for system customization. By providing access to all of the major panel brands, you can optimize for low upfront costs, high output in the long-term or specific panel specifications that are beneficial in Massachusetts, like high resistance to the heavy snow that can fall in parts of the state.

What I Don’t Like About Momentum Solar

There are some downsides to working with Momentum, too, though. While I think it’s the best company for customer service in general, there are some negative reviews related to the provider dragging its feet on carrying out warrantied repairs. That could mean some frustration and missed savings if you run into a problem.

Momentum is also lacking when it comes to optional add-on products and services. For example, it doesn’t offer any energy efficiency upgrades, which could help you get the most out of your panels. This isn’t a huge deal in Massachusetts since the typical home uses far less energy than the national average, but I still would like to see some options here for future-proofing your home from above-average electricity prices.

Momentum also doesn’t install EV chargers. EVs are more prevalent in the Bay State than most others, and the mandate for all newly registered light-duty vehicles to be zero-emission vehicles (ZEVs) by 2035 means that access to at-home charing is going to be more important in the near future.

Momentum Solar Installation Process and Timeline

The process of going solar with Momentum is going to follow a similar trajectory that you’d see with most installers. You’ll schedule an in-person inspection for a rep to take measurements and inspect your property and roof. The company will then design your system and provide a contract for you to sign. After that, the in-house installation team will install your system and schedule the necessary inspections before activation. The concierge service and use of in-house installers should make this entire process go smoothly compared to other companies.

Momentum doesn’t specifically state how long the solar conversion process will take, but I’d expect it to be about average, which should be between 6 and 8 weeks from the initial call to system activation.

Momentum Solar Standard Services & Financing 

25/25

Momentum Solar scores as high as possible in our ratings when it comes to its standard offerings and financing options. It gets maximum points for using in-house installers, which can cut down on delays, miscommunications and the potential for different companies pointing fingers if there’s an issue with the process.

It installs solar batteries, which I love to see, given the nationwide move toward less beneficial net metering policies. However, I don’t recommend installing batteries in Massachusetts right now because the current net metering policy is excellent and should allow you to offset your electric consumption and nearly eliminate your monthly bill even without on-site storage. Still, residents sometimes see extended power outages, so having the option for batteries is nice to have.

Finally, Momentum Solar has its own app that gives you real-time data about your solar array and energy consumption in your home. This can help you keep track of your savings and even reduce your electricity usage to boost your savings over time. The app also gives you access to make your loan or lease payments, which is a nice bonus in terms of convenience.

Cost and Financing Options

The typical solar array in Massachusetts costs around $24,180 before incentives, according to our research, and while this is about $6,000 below the national average, it’s still expensive and might be inaccessible for some residents. Thankfully, Momentum accepts cash purchases, solar loans, leases and power purchase agreements (PPAs).

I recommend a cash purchase, if possible, because it means the highest long-term savings — an average of over $37,000 in Massachusetts. Paying in cash is the least accessible option, but it does give you access to the federal investment tax credit (ITC), which provides an effective potential savings of over $7,250 in your area.

A solar loan is more accessible and just requires a small down payment, and it still leads to panel ownership, which should increase your property value, just like a cash purchase. A loan will come with interest, which amounts to around $5,000 over the life of most solar loans, and that will cut into your net savings and increase the overall cost of your system. Loans also let you take the ITC.

Solar leases are like rental agreements, so you never own the system and won’t be eligible for the federal tax credit. They also provide average lifetime savings of around $5,000, which is about $32,000 lower than a cash purchase and around $27,000 lower than with a loan. I don’t recommend leases due to the lower savings, but I love that Momentum offers them because they are far more accessible than pay-to-own options, usually requiring no down payment at all.

PPAs are similar to leases, although they tend to lead to slightly lower savings.

Momentum Solar Extra Services Offered 

2/5

Momentum’s core services are great, but the company is lacking a bit when it comes to its add-on services. It does get some points for providing roof repairs and replacements, which can help prepare your home for solar and avoid having to pay to remove and reinstall your panels if you need roof work down the road. In-house roof services also means you don’t have to find and coordinate with another contractor to go solar, and if you ever experience a roof leak — which is more of a risk in Massachusetts than many other states due to the above-average rainfall and snowfall — you’ll only have one company to blame, which can reduce finger-pointing.

Momentum loses some points here because it doesn’t offer any energy efficiency upgrades or EV charger installations. As I mentioned before, Massachusetts already has a below-average rate of electricity consumption, so a lack of efficiency upgrades isn’t so bad, but I do prefer companies that offer them, as it shows that a provider gets the big picture and understands that clean energy goes hand-in-hand with overall sustainability. EV chargers would also be nice, especially since all light-duty vehicles in Massachusetts will have to be ZEVs come 2035, so the option to prepare for at-home charging now would be preferred.

Momentum also doesn’t provide company monitoring for your panels. This isn’t a huge deal, in my opinion, because you can use the Momentum app to monitor your system yourself, but it would be nice for some added peace of mind.

Momentum Solar Environmental Impact & Sustainability Practices 

7.5/10

Installing an appropriately-sized solar array on your home will absolutely reduce your carbon footprint and do right by the environment, but that doesn’t mean solar panel manufacturing shouldn’t also be as sustainable as possible. I research the panel brands each manufacturer installs to see the overall sustainability of the products offered. Specifically, I look for manufacturers that use recycled materials in the manufacturing process, has a program in place to help recycle used panels and doesn’t have a history of moral or ethical issues, like unfair pay, poor working conditions, slave labor, racism or child labor.

Momentum works with all tier-one panel brands, which means it has the highest single-panel sustainability score possible in our ratings.

Personally, I’d recommend going with Maxeon, REC or QCells panels, both of which are available from Momentum. They all tie with the best brands in the industry for sustainability, and they have otherwise impressive specifications, including above-average efficiency ratings and low degradation rates, both of which help boost long-term sustainability by offsetting more of your electricity consumption over time.

Momentum Solar Equipment Quality & Reliability 

20/25

Solar equipment is expensive, even in Massachusetts, where systems are around $6,000 less expensive than the national average. That’s why it’s crucial that you choose high-quality panels with solid warranty coverage to maximize your system’s longevity and, in turn, your savings.

Again, Momentum works with all of the tier-one panel brands, so it gets the maximum single-panel score possible in our ratings. Of these brands, Maxeon, REC and QCells are the ones I’d recommend most. When evaluating panel brands, I look at 18 metrics, and I prioritize the specs that I believe are most important in Massachusetts. For example, the above-average snowfall in the state means that panels with a high snow load rating are going to provide the most peace of mind. REC and QCells panels have some of the highest snow load ratings in the industry — 7,000 and 8,100 Pascals, respectively, compared to the industry average of 5,870 Pascals.

Since electricity prices in Massachusetts are well above average and the state sees fewer sunny days than most other states, I also suggest panels that have high efficiency ratings to help ensure you aren’t paying to pull power from the grid and that your panels continue maximizing savings for decades to come. Maxeon, REC and QCells panels all perform well and better than average when it comes to all of these specifications.

Warranties and Guarantees

A big part of equipment reliability and long-term performance is the warranty coverage you get with your system, so I also recommend prioritizing lengthy warranty packages both from your panel manufacturer and the installer itself. I look at 4 warranties for each provider I review.

First is the equipment warranty, which is a manufacturer’s warranty to protect you from defects. Defects can reduce power output and decrease your savings, which can end up being a big deal in Massachusetts, where paying for power from the grid is more expensive than in most other states. The industry average for this coverage is 25 years. REC and QCells match the average, but Maxeon has a leading manufacturer’s warranty that lasts for 40 years, making it the best option for protection.

Second is the production warranty, which also comes from the manufacturer and guarantees long-term performance from your panels. You need to look at the starting efficiency, warranty term and degradation rates to get the complete picture of the value presented in the coverage. The standard is 25 years with between 85% and 92% of the starting efficiency remaining at that time. REC, QCells and Maxeon panels all fall above the average remaining efficiency, but Maxeon goes above and beyond with an incredible 40-year warranty for power output, again making it the best option for long-term performance.

Next, I look at the workmanship warranty. This comes directly from Momentum and guarantees covered repairs and maintenance if there’s an issue that stems from the installation labor. I think this is the most important warranty to consider in Massachusetts, as the above-average precipitation can lead to major property damage and high out-of-pocket costs if your installer makes a mistake. Most companies provide a labor warranty of around 12 years, but if you go with Maxeon panels through Momentum, you can get up to 40 years of coverage for the labor, which is outstanding.

Finally, I look for roof leak warranties, which cover roof leaks and water damage related to your panel installation. Most companies don’t offer these, and unfortunately, Momentum is among those that don’t. A roof leak warranty would be especially nice in Massachusetts, where precipitation is above-average, making the risk of leaking higher.

Momentum Solar Company Reputation 

14.5/25

Momentum is a great pick for customer service, but unfortunately, its reputation in the industry leaves a little to be desired. The company was founded in 2009, so it has 15 years of experience behind it. This is a good sign, as some companies — especially in a highly competitive market like the one in Massachusetts — struggle to stay afloat and end up going out of business just a few years after they open their doors. Momentum’s experience suggests longevity, which means your warranty coverage should stay intact for years to come.

It loses points in terms of its reputation rating because it doesn’t use NABCEP®-certified installers and because it’s not an SEIA member. NABCEP® certification requires training above and beyond what’s required to hold an installer’s license, so it suggests a more professional installation that’s less likely to have problems related to the labor. The company’s experience somewhat makes up for this, in my opinion, but it still loses points for a lack of certification. SEIA membership helps establish a company’s commitment to the industry, so again, not a big deal for a company with 15 years of experience behind it, but I still would like to see an affiliation with organizations like the SEIA.

Momentum maintains an A+ rating and a 3.05-star customer review rating with the BBB, which is above average, especially for a company of this size. I think these are good signs that you’re likely to be pleased with your installation and overall experience. The company’s TrustPilot rating — 1.8 stars — is lacking, though, so Momentum loses some points in our ratings accordingly.

Consumer Reviews and Testimonials

Overall customer ratings don’t always paint a complete picture of the service you can expect from a provider, as some customers complain about things like aggressive marketing tactics, especially within the solar industry. To get the whole story, I read through dozens of Momentum Solar reviews to get a sense of what the company does well and where it could improve.

Many of the positive reviews rave about the customer service and communication, which is unsurprising, given the concierge service Momentum offers. Positive reviews also note that they see real-world savings in line with the expectations they had when they signed the contract. Negative reviews mention delays in getting warranty claims addressed, as well as some delays in getting the initial installation completed.

I’ll include a positive and negative review below that I believe provide an overview of the best and worst service you can expect if you choose Momentum.

“[My rep] has been an exceptional resource. He has helped to get all my questions answered timely and accurately. He always returned calls promptly. He was able to navigate my process from lease to a buy out option in order to keep the process going. He was confident in ensuring the rebate would be applied and had updated paperwork to reflect the rebate sent to me for my signature. It was a pleasure working with [him] to ensure that [I had] everything I needed, and he was able to walk me through details that I wasn’t sure how to complete.” — Anne B. via BBB

“Terrible. They sent the salesperson and he explained to me the entire process that was followed to place the panels. They made me replace the roof with a new one. Then they charged a higher monthly fee than the one we had agreed upon. More inspections than he actually told me. In short, all the information he gave me was totally false. I called them many times, [but] they don’t answer and they don’t respond.” — Maria I. via BBB

Momentum Solar Customer Service 

8/10

The last part of our company scoring is based on customer service. This is a subjective metric that I come up with based on a secret shopper call I made to Momentum, as well as the general sense of the company I get from reading through customer reviews. When I called Momentum, I was pleased to find that the representative was helpful and friendly. They were knowledgeable about the process and solar in general, and it didn’t seem like it was just a salesperson looking to schedule an inspection or get a contract signed.

I also read through dozens of customer reviews, and while there are some negative reviews, I found that the majority of them were positive. Some negative reviews included complaints about aggressive sales tactics, which I don’t love, but I also don’t think that’s an issue that means you should pass on Momentum. Some customers also complained about delays in getting warranty claims taken care of, so I deducted a few points here, but overall, I think the customer service you can expect from Momentum is quite good.

Why We Chose Trinity Solar

Trinity Solar is a great choice if you want the ability to customize your system. Much like Momentum, they work with a variety of tier-one solar panels, offer backup battery installations, electrical system upgrades and roofing services. They don’t install EV chargers, but it can handle just about any other piece of equipment or upgrade you’re looking for. They also accept 3 financing options, including a $0-down lease to help make solar more accessible.

Trinity also has a stellar reputation in the solar industry. It has over 30 years of experience, uses NABCEP®-certified installers and has handled over 100,000 installations with its in-house team of installers. On top of that, it includes a roof leak warranty, which is ideal in a place like Massachusetts, where heavy precipitation can be an issue, and it maintains above-average customer review ratings, including a 3.51-star rating with the BBB.

Trinity has been a target of class-action lawsuits for aggressive marketing tactics, but overall, I think the company’s reputation and offerings make it an excellent option. 

What I Like About Trinity Solar

Most of what I have to say about Trinity is positive. It uses in-house installers that are certified by NABCEP®, which helps make the installation process go as smoothly as possible. It has a nice selection of services and equipment, including solar batteries, roofing services and energy efficiency upgrades like upgrades to your electrical system, and it accepts all of the main payment options to help you optimize for a low upfront cost or long-term savings.

Trinity’s customer reviews mostly rave about the positive customer experience, too, including great communication, professionalism and knowledgeable salespeople and installers. The company also has over 30 years of experience, so going solar with Trinity means you’re getting a company with decades of experience and a proven track record to design and install your system.

Lastly, I’m pleased to see that Trinity installs EV chargers. Massachusetts is one of the top states in the country for EV adoption, and a recent bill passed means that all new light-duty vehicles purchased after 2035 in the state will need to be ZEVs. That means most homeowners will eventually want at-home charging. Having access to at-home charging options from Trinity is great.

What I Don’t Like About Trinity Solar

Trinity Solar does have some negative reviews. Most of these pertain to aggressive sales tactics, including robo-dialing that landed the company a class-action lawsuit. Customers also complain about misrepresentations made by their salespeople, including inflated production estimates and savings. I still think Trinity is a solid option, but it’s especially important to go into your initial contact understanding what your property needs and what you can save. This is a shame because Trinity otherwise has mostly positive customer reviews. Potentially shady business practices like this give the solar industry a bad name and make it more challenging for homeowners to make good decisions regarding their clean energy conversion.

Trinity Solar Installation Process and Timeline

Trinity doesn’t mention an average timeline for installation on its website, but since there aren’t many customer complaints on the BBB or TrustPilot about delays in the installation process, I’d expect it to be around the standard: 6 to 8 weeks from initial inspection to system activation.

The process will be the same as what you’d expect from other providers. You’ll have an in-person inspection so that a rep can take measurements and assess your property for solar viability. The design team will design your system and then pull permits after you sign your contract. On the installation day, an in-house team will install your equipment, and then a rep will schedule final inspections before activating your system.

Trinity Solar Standard Services & Financing 

25/25

I’m happy to report that Trinity gets perfect scores in our ratings when it comes to its core services and financing options. It gets full marks for using an in-house installation team, which can help avoid delays and finger-pointing toward a third party if something goes wrong. It offers solar batteries, too, which I think is an important add-on to have access to, especially as the net metering policies in the U.S. are on the decline following California’s move to net metering 3.0, which reduces the credit rate for excess energy by around 75%. I don’t recommend batteries in Massachusetts now because the net metering policy is outstanding, but I do think it will be increasingly important to have access to them in the future, as that policy is bound to decline.

Trinity doesn’t have its own solar monitoring app like Momentum does, but you do still get access to self-monitoring via the Enphase or SolarEdge app, depending on which inverters the company installs. Just a quick note that, if you have the choice, I recommend microinverters from Enphase, which is what I have on my system. This allows most of your system to remain up and running even if one panel runs into a problem, and this is crucial in Massachusetts because electricity is so much more expensive than the national average, so whole-system outages are going to cut into your savings far more than they would in most other states. Self-monitoring through these apps also helps identify panel damage early to get a fix in place as quickly as possible and get back to maximum savings.

Cost and Financing Options

Trinity Solar accepts cash purchases, solar loans, leases and PPAs. If you can afford it, I recommend going with a cash purchase. This will be the most expensive option upfront, but owning your panels outright means you can take advantage of the federal tax credit — an average potential value of $7,254 in Massachusetts — and you’ll avoid interest on a loan, pushing the average lifetime savings for going solar in Massachusetts up to $37,303. Owning your system also means your system will boost your property value.

If you can’t make a cash purchase work, I’d recommend going with a loan from Trinity. You get the same perks as with cash — including boosted property value, access to the ITC and higher savings than with a lease — but you will pay interest. The interest will increase your long-term system costs by an average of around $5,000, according to our research, so your lifetime savings will drop to a still-respectable $32,000, on average.

A lease can be a good option in some cases, but I generally recommend avoiding them. They don’t let you take the federal tax credit, so you miss out on the average $7,250 credit to your income taxes owed, and your property value won’t increase. A lease saves you much less over time — usually around $5,000 — so you’ll miss out on around $32,000 of lifetime savings as opposed to a cash purchase. Leased systems can also be problematic if you go to sell your home and the buyer doesn’t want to assume the lease payments. In that case, you could be on the hook for a pricey early termination fee. The benefit of leases, though, is that your upfront payment is $0, so it’s an enticing option from the perspective of low upfront payment and accessibility.

A PPA is similar to a lease, but instead of paying a monthly rental fee, you agree to buy the power your panels generate at a discounted rate. PPAs come with the same benefits and drawbacks as a lease, but savings tend to be a little lower, usually between $4,000 and $5,000.

Trinity Solar Extra Services Offered 

5/5

Trinity also gets perfect marks when it comes to the non-standard options. It handles roof replacements and repairs in-house, which means you’ll only be dealing with one company if you need to repair or replace your roof before it’s safe to install panels. You can avoid having to search for and coordinate with a roofing company, and if something goes wrong, there’s only one company to hold accountable. Trinity also offers some upgrades to your electrical system to ensure it can handle the load your panels will place on it, and this makes Trinity a one-stop shop for all things solar.

Trinity also installs EV chargers, which I love to see in an EV-friendly state like Massachusetts. As I mentioned before, the new law in Massachusetts requires that all new light-duty vehicles registered after 2035 be ZEVs, and that means at-home charging is going to become more and more important to have access to as time goes on. I’m happy to see Trinity offering EV chargers in its lineup so that customers can plan for the future and still have a single company handling — and remaining accountable for — all of their solar equipment.

Trinity also offers company monitoring for your panels, which means you won’t have to check your system performance periodically to find production problems — the company does it for you. This makes your life a bit easier by taking the responsibility out of your hands.

Trinity Solar Environmental Impact & Sustainability Practices 

7.5/10

Going solar reduces your carbon footprint because you avoid calling on fossil fuels for your electricity. According to a study done by Columbia University, solar panels reduce carbon dioxide emissions more than trees on a per-square-foot basis, so installing a full array on your home is going to have a major positive impact on the environment. However, solar panel manufacturing still calls for resources and uses energy during production, so I always evaluate installers based on their overall sustainability. A good way to do this is to look at the panel brands the installer offers and then research how sustainable those companies are.

Trinity Solar uses a variety of tier-one solar panel brands, which means you have some options and can pick the brand that has the greatest positive impact. I look at a few things to determine overall sustainability, including the use of recycled materials during production, a dedicated recycling program in place for old panels that reach the end of their lifespan, manufacturing in the U.S. and a lack of social and ethical issues in the workplace, including unfair wages, dangerous working conditions, slave labor and more.

Since Trinity uses a variety of brands, it scores the highest possible rating for a single panel when it comes to sustainability. The company primarily works with QCells panels, which is a shining example of a sustainable manufacturer. It uses recycled materials, has an end-of-life recycling program and doesn’t have a documented history of workplace or ethical problems. QCells panels just lose a few points because they aren’t primarily manufactured in the U.S., but overall, I think QCells is a great brand for maximizing the environmental benefit of going solar.                                                                                                              

Trinity Solar Equipment Quality & Reliability 

14.03/25

Product sustainability is important, but I also think it’s crucial to consider the reliability and quality of the equipment, too. Not only will high-quality, long-lasting products save you more money over time, but they also mean a longer lifespan that further reduces CO2 emissions, adding to their sustainability. I look at a few things to determine the quality and reliability of the panels each installer offers.

One of the most important things to look at in Massachusetts, in my opinion, is the efficiency rating. Panels with a higher efficiency rating generate more power and lead to a higher level of offset for your home. This is especially important in Massachusetts, where the cost per kWh for electricity from the grid is about 172% of the national average. Every additional kWh you offset with higher efficiency ratings is going to equate to above-average savings in a place like Massachusetts. The QCells panels Trinity primarily work with have an above-average efficiency rating topping out at 22%, which should be plenty to get the most out of your system.

I also think it’s important to consider the degradation rate. All panels lose efficiency over time, but each brand guarantees a specific rate of degradation. The slower the degradation, the longer your panels will continue offsetting your electricity consumption. A higher level of offset means more long-term savings, especially in Massachusetts where the cost of energy is above average. QCells panels guarantee that your panels will maintain 90.58% of their starting efficiency after 25 years. The standard is between 85% and 92%, so QCells is, once again, a top performer and should help maximize savings.

Another important thing to consider is the maximum snow load your panel brand can handle, especially in the western parts of Massachusetts, where annual snowfall can be double the national average. The snow load rating tells you how much force your panels can safely hold without sustaining damage. QCells panels have the highest snow load of any of the tier-one panels we’ve reviewed: a rating of 8,100 Pascals. For context, the industry average is 5,870 Pascals.

Warranties and Guarantees

In addition to individual panel specifications, it’s also crucial to consider the warranty coverage you get with your system. I look at 4 types of warranties to get a complete picture of what each installer brings to the table.

First, I consider the equipment warranty. This comes from the manufacturer and protects you from manufacturing defects, which can lead to panel failures and decreased production and savings over time. The typical coverage is for 25 years, and the QCells panels that Trinity primarily works with matches this.

Second, I look at the production warranty, which, in my opinion, is more important in a place like Massachusetts, where faster degradation is going to have a larger negative impact on your long-term savings due to the high cost of electricity in the area. Most manufacturers guarantee between 85% and 92% remaining efficiency after 25 years. As I mentioned above, QCells guarantees 90.58% efficiency remaining after 25 years, putting it toward the top of the average range.

Next, I consider the workmanship warranty. This usually comes from your installer — Trinity, in this case — and protects you from panel malfunctions that result from a bad installation. Long workmanship warranties can help reduce the risk of roof leaks and panel issues, so they’re especially helpful for peace of mind in Massachusetts, where precipitation and electricity costs are both above average. The average labor warranty is around 12 years, and Trinity falls short here with just a 5-year workmanship warranty. I do think the NABCEP® installers and the 30 years of experience help reduce the risk of problems with the installation labor, but I’d still like to see better coverage from Trinity here.

Finally, I look for roof leak warranties, which specifically protect you from roof leaks that result from roof penetrations to install your panels. This is really great coverage to have in Massachusetts because above-average rainfall and snowfall mean a higher risk of leaks. Unfortunately, Trinity doesn’t offer a roof leak warranty, which is the norm in the solar industry.

Trinity Solar Company Reputation 

19.5/25

Trinity Solar has an outstanding reputation in the solar industry. First off, it has over 30 years of experience and over 100,000 installations under its belt. In a highly competitive market like Massachusetts with nearly 200 competing companies, this kind of longevity suggests that the company knows what it’s doing and will continue its success in the future. Companies that go out of business can void your warranty coverage in the process, so Trinity’s experience suggests that you’re safe from that potential problem.

Trinity uses NABCEP®-certified installers, which means they go through additional, specialized training that helps ensure a solid, problem-free installation. The company is also an SEIA member, which is a good sign that its invested in the solar industry and, again, will be sticking around for the long haul.

I also looked at Trinity’s ratings on the BBB and TrustPilot, which are good indications of the kind of service you can expect from the provider. It maintains an above-average 3.51-star customer rating and an A+ business rating with the BBB. This is impressive, especially for a company of this size. It has a 2.8-star rating on TrustPilot, but all 3 of the reviews are 1 star, and the overall rating is weighted based on the lack of reviews. Our rating system doesn’t account for weighted scores, so Trinity doesn’t lose many points here, but I did deduct some points in the customer service section for this reason.

Consumer Reviews and Testimonials

I read through dozens of Trinity Solar reviews on sites like the BBB, TrustPilot and Google Reviews to get a better sense of where this company succeeds and where it could stand to improve. Many of the positive reviews mention knowledgeable staff, professional and courteous installers and a system that meets expectations in terms of energy production and savings on utility bills. A lot of the negative reviews pertain to the aggressive marketing and sales tactics, which I’m not a fan of, and some mention issues with getting warranty claims addressed, which is a major issue in my book. Thankfully, the positive reviews are more common than negative ones related to the actual service you’ll receive.

I’ll include one positive and one negative review below to give you a better idea of what to expect.

“Would recommend Trinity solar to anyone who asks. Cannot say enough good things about my primary contact. He was responsive, professional and always willing to help throughout every step of the process. We had a few hiccups with National Grid approving the setup, but Trinity went above and beyond to make sure it was resolved quickly and with minimal headache for me. The amount of money I’m saving now compared to National Grid is staggering. Energy costs decreased by 70%. Just an overall great experience.” — Brian D. via BBB

“So far 3 service calls and still no production. Tried to make a new service appointment and [the] representative said it was impossible at this time. I have 42 panels and no electricity. Thank you, Trinity Solar; just keep taking my money and not giving me the support. No help, no service, no parts, no explanation, no good!!!” — William H. via TrustPilot

Trinity Solar Customer Service 

5/10

The final score for Trinity is for customer service, which I personally come up with based on 2 factors. First, I called Trinity as a secret shopper to see what the experience was like. Thankfully, I didn’t run into the aggressive sales tactics that some customers complain about. The representative was kind and courteous, and they were helpful in answering a few questions I asked about the viability of solar on a home in Massachusetts, and they were honest and said solar batteries weren’t usually necessary in the state because of the net metering program. To me, this is indicative of a company that cares about customers and puts them first.

Unfortunately, I had to deduct some points here because of the customer complaints, particularly those pertaining to getting warranty claims addressed. Quite a few homeowners complain about a lack of communication from the company after installation and especially related to issues they experienced with their system’s functionality. This is a major downside, in my opinion, because solar is expensive and you want the peace of mind you get from an installer that stands behind its work. Unfixed issues also have a greater negative impact on your long-term savings in Massachusetts than in most other states because of the high cost of electricity, so I had to deduct some points for the overall customer experience.

Why We Chose SunRun

SunRun is the best solar company in Massachusetts if you know you want a solar lease and want the best protection plan to keep your investment into clean energy protected. The company accepts cash payments and solar loans, too, but the coverage you get on a leased system includes free maintenance and repairs throughout your entire lease agreement, as well as a higher production guarantee than most companies offer, which is especially helpful for avoiding the above-average cost of electricity in Massachusetts.

I personally wouldn’t go with SunRun unless I knew I wanted a lease, as the warranty protection you get with a cash purchase or solar loan pales in comparison to what some other providers, like Trinity, offer. The company has also had some issues with customer service in the past, even related to getting warranty claims sorted out, but I’ve been tracking the company for years, and it seems like it has recently made improvements to the overall customer experience it provides.

What I Like About SunRun

SunRun prioritizes leases, which I don’t love, but if you know you want a lease, you can’t beat the protection you get for your system. That includes a 90% production guarantee, which means the energy output estimate the company gives you in your estimate is going to be more accurate than what most competitors offer — some don’t offer any at all. SunRun also includes free company monitoring to detect problems early, as well as free maintenance and repairs for the entire 25-year lease agreement. If you’re concerned about damage to your panels from the heavy rain and snowfall in Massachusetts, SunRun is going to provide more peace of mind than most other companies.

SunRun’s services are also robust, including battery installations, EV charger installations, energy efficiency upgrades for your home and more. Aside from roof repairs and replacements, SunRun is a one-stop shop for going solar, which means you can have a single company to hold responsible for your entire system.

What I Don’t Like About SunRun

SunRun has had some issues in the past with customer service, including complaints related to delays in getting issues fixed under warranty. This is a pretty significant drawback, but there are also plenty of reviews that rave about the communication and timeliness of necessary repairs, so it seems like you kind of get the luck of the draw based on your installer. Speaking of which, SunRun is a massive company that uses third-party installers to carry out the labor, and this can contribute to delays and finger-pointing in the case of system issues, so the potential for getting a subpar installer is something to consider.

SunRun also doesn’t handle roof work, so if you need roof repair or replacement before installing panels, you’ll need to coordinate with a separate company beforehand. This can also present issues if there’s a leak — which is a higher risk in a place like Massachusetts, where rainfall and snowfall are above average — as the companies could blame each other for the issue, potentially leading to problems and delays in getting the issues fixed.

SunRun Installation Process and Timeline

SunRun breaks down the entire installation process and timeline on its site, and it estimates that it can take anywhere from 8 weeks to 6 months to go from your initial contact to system activation. This is longer than the average, but a good portion of the process — 2 to 8 weeks — is for permitting, where delays could result from your local building department rather than the installer itself.

The process involves an initial consultation and property inspection, followed by a system design by a SunRun representative. Once you approve the design and sign your contract, SunRun will pull all necessary permits, install your equipment, schedule final inspections and then activate your system to start generating electricity for your home. The use of third-party installers can cause some delays throughout this process that you might not see from an installer that uses an in-house team.

SunRun Standard Services & Financing 

22/25

SunRun gets nearly perfect marks in our ranking categories for its standard services and payment options. It loses some points because it uses third-party installers, as this means some variation in the customer experience during the installation. If you get a highly-experienced installer, you might not run into any issues, but some customers complain about less professional installation teams and even errors made during the installation that lead to issues down the road.

It installs solar batteries, which I don’t recommend for most Massachusetts homeowners since the statewide net metering policy effectively lets you use your utility company as a battery to maximize savings. Batteries can be helpful for maintaining power through extreme weather, though, so if your area loses power frequently in snow storms or thunderstorms — particularly in Western Massachusetts — then the option to add a battery is a nice perk to have.

SunRun also has a non-backup battery called Shift™, which is exclusive to SunRun. The Shift™ battery optimizes your grid usage when your panels aren’t generating enough to cover your consumption, which can help maximize savings for homeowners who have time-of-use energy plans or don’t have access to net metering. This battery is only available in California and Hawaii right now, but I hope SunRun will start installing it in Massachusetts if and when the net metering policy declines in the state.

SunRun includes access to its free mobile app with all installations. The app gives you real-time data on your consumption and energy production, which can help you keep an eye on your system and identify problems with production before they become too severe. This is especially helpful in Massachusetts, where the cost of electricity from the grid is well above the national average, and dips in production will lead to a greater hit to your long-term savings.

Cost and Financing Options

Solar is expensive in Massachusetts, with the typical system totaling $24,180 before any incentives, according to our research. As such, I’m happy to report that SunRun accepts cash and loans for systems for maximum long-term savings, as well as a $0-down solar lease for keeping your upfront costs to a minimum.

I always recommend homeowners go with a cash purchase, if possible, because it leads to the highest net savings over time — an average of over $37,000 in Massachusetts — increases the value of your home and lets you take the federal tax credit, which averages around $7,250 in your area. Cash purchases also won’t complicate the sale of your home, as the buyer won’t need to take over any payments.

If you can’t swing the high upfront cost of a cash purchase, a solar loan is your next best option. Loans lead to panel ownership, too, so you can still take the federal credit, and your home value will go up. Unfortunately, a loan means you’ll pay interest, totaling around $5,000, on average, which brings the typical net savings from $37,000 down to $32,000. Loans can also complicate the sale of your property, as the buyer will need to agree to take over the loan payments. However, loans come with a much smaller down payment requirement, making them far more accessible.

A lease option is what SunRun prioritizes, which I’m not a big fan of since leases are less beneficial to you as a customer. You miss out on the ITC, your property value won’t increase and a buyer will still need to agree to take over the lease payments if you sell your home. Leases are a $0-down option, so they’re the most accessible, but your lifetime savings will average around $5,000, which is $27,000 to $32,000 less than with a loan or cash purchase, respectively.

While I recommend cash purchases or solar loans for the greatest financial benefit, I’d personally go with a different company unless you know you want a lease. SunRun’s warranty coverage and perks like free maintenance and repairs only apply to lease agreements, so you’re better off with a different provider, like All Energy, Momentum or Trinity if you can make a loan or cash payment make sense for you.

SunRun Extra Services Offered 

3/5

SunRun also scores well when it comes to the extra services it offers, and it only loses points because it doesn’t handle roof replacements or repairs. If you have a newer roof, this isn’t an issue, but homeowners with older roofs will need to coordinate with another company to get the roof work done before moving forward with SunRun. If you run into a problem with roof leaks after the installation, there’s a chance the two providers will blame each other, resulting in delays in getting a solution in place.

Aside from roof work, SunRun’s add-on options are plentiful. It offers energy efficiency upgrades, including its SPAN smart electrical panel, which gives you information about and control over your electricity consumption. Smart electrical panels can help you cut down on energy usage, meaning you get more value from your panels and a better chance at avoiding the above-average electricity prices in Massachusetts.

It also has a deal with Ford to provide a two-way EV charger if you have a Ford F-150 Lightning®. The system allows you to charge your truck or use the truck’s large battery to power your home through blackouts. Since Massachusetts sees heavier snowfall than most states, this can be an extremely useful combination. SunRun also installs standard EV chargers in case you don’t have an F-150 Lightning®. Standard EV charger installation is a perk I specifically look for in Massachusetts, as the state is mandating that all newly registered vehicles in the state be ZEVs, so home charging capability is going to be all but necessary in the future.

Finally, SunRun offers professional system monitoring, which means issues with production should be found immediately. This can help you maintain sufficient electricity production to avoid the high electricity costs in your area over the long run. System monitoring is included for free with all leased systems from SunRun.

SunRun Environmental Impact & Sustainability Practices

According to the U.S. Department of Energy, solar equipment has a positive impact on the environment, as it reduces CO2 emissions and helps slow down climate change. However, it’s also important to consider the sustainability of the solar manufacturing process and ensure it’s done as responsibly as possible. That’s why I assess individual panel brands each installer works with to gauge the manufacturer’s overall sustainability. I look for the use of recycled materials like aluminum and glass during production, recycling programs that help keep used panels out of landfills and a history of socially sustainable business practices.

SunRun installs panels from REC, QCells and Canadian Solar, all of which get maximum points in our solar panel reviews in terms of sustainability. All three use recycled materials to produce their panels, they have end-of-life recycling programs for used panels and none of them have documented issues with slave labor, child labor, racism in the workplace, unsafe working conditions or unfair pay.

SunRun Equipment Quality & Reliability 

16.65/25

SunRun’s equipment also scores quite high in terms of its quality and overall reliability, which is important for long-term performance and maximized savings. When I review installers for equipment quality, I look at 10 different panel specifications, as well as 2 warranty options from the installer to see what kind of reliability and longevity you can expect from their equipment. In Massachusetts, specifically, I personally think efficiency, degradation and max snow load are most important.

A panel’s efficiency tells you the percentage of the sunlight that hits it that it can convert into usable energy. The higher the efficiency rating, the more electricity it will generate and the higher your savings will be. Panels with a max efficiency over 22% are considered the best of the best, and all three brands that SunRun installs hit over that mark. Canadian Solar panels have the highest of the 3 at 23.1%.

Panels lose efficiency over time in real-world conditions, so the degradation rate gives you an idea of how long your panels will be able to keep up with your consumption and continue to save you money on the above-average energy bills in Massachusetts. Most tier-one panels guarantee that between 85% and 92% of the starting efficiency will remain after 25 years. QCells and REC both guarantee over 90% after 25 years, which is outstanding. Canadian Solar panels maintain 89.4%, which is still very good. All 3 panel brands from SunPower perform well in terms of long-term durability.

Parts of Massachusetts see about double the average national snowfall, so I also think snow load ratings are important to consider. These tell you how much force your panels can resist from above. Tier-one panels average around 5,870 Pascals. REC and QCells panels have the two highest ratings in the industry at 7,000 and 8,100 Pascals, respectively. Canadian Solar falls below the average at 5,400 Pascals. I’d recommend REC or QCells panels, given the potential for heavy snowfall in Massachusetts, especially if you live in the western portion of the state that sees the highest accumulation.

Warranties and Guarantees

In addition to the panel performance specs, it’s important to look at the warranty coverage your manufacturer and installer provide, as these will keep you insulated from out-of-pocket costs for repairs or replacements if something does go wrong. There are 4 types of solar warranties to consider.

First is the equipment or manufacturer’s warranty, which covers equipment replacement in the event of an issue stemming from a defect. This is absolutely a good thing to have, but I personally think it’s the least important of the bunch. This is partially because panel defects aren’t as common as some other issues, like roof leaks, and most manufacturers provide a standard 25-year equipment warranty, so there’s little variation across the board. REC and QCells meet that standard, and Canadian Solar goes above and beyond with 30 years of coverage.

More important, in my opinion, is the performance warranty, which guarantees a maximum amount of degradation, usually over 25 years. This is likely going to lead to greater savings than an equipment warranty in Massachusetts because faster degradation will lead to decreased production over time and an increased risk that you’ll have to pay for power from your utility company, which comes at a rate that’s around 172% higher than the national average. Most manufacturers guarantee between 85% and 92% efficiency after 25 years, and all 3 panel brands from SunRun meet those standards.

Third, I look at workmanship warranties, which protect you from problems stemming from the actual installation labor. This can help avoid problems like roof leaks, which are a higher risk in Massachusetts due to the above-average precipitation in the area. The standard labor warranty is 12 years. SunRun includes an above-average 25-year workmanship warranty for leased systems but only a 10-year warranty if you buy your equipment with a loan or cash. This is another reason why SunRun is a solid option if you know you want a lease, as it gives you total peace of mind for the length of your agreement.

Finally, I look for roof leak warranties, which add specific protection and coverage if your system installation does lead to a leak. Most installers don’t offer a roof leak guarantee, but SunRun includes 10 years of coverage regardless of how you pay for your system. This makes SunRun stand out against many competitors, and it’s especially nice to have in Massachusetts, where rainfall and snowfall are above average.

SunRun Company Reputation 

19.5/25

SunRun’s reputation in the solar industry has been a bit up and down over the past few years, but it seems like the company is putting more of an emphasis on customer satisfaction and care, as its current customer ratings are a few points higher than they were in the late 2010s and early 2020s.

One thing SunRun has going for it is its sticking power in the industry, as it has been around since 2007 and has over 15 years of experience. The solar industry is extremely competitive, and the fact that SunRun has been serving Bay Staters for so long, despite the nearly 200 competitors, is a testament to its success. Some companies that enter the solar space end up going out of business in the first few years, which can mean voided warranties. SunRun persisting for so long suggests that it’s here to stay, which means your warranty coverage likely will be, as well.

SunRun outsources to third-party installers, but they’re certified by NABCEP®, so they have training that goes above and beyond what’s legally required to ensure a professional and proper installation. Along with SunRun’s protection plans, this offers greater peace of mind that your system will continue functioning for decades to come. SunRun is also an SEIA member, which helps establish the company in the solar industry and suggests that it’s financially invested in clean energy.

As I mentioned, SunRun has made some recent improvements to its customer review scores and business standing, as well. It has an A+ rating and a 3.62-star customer rating with the BBB, which is well above average and quite impressive for such a large company. It has a less impressive 1.3-star rating with TrustPilot, though, so it loses some points in our rating system.

Consumer Reviews and Testimonials

Many customers are put at ease more by specific customer reviews that illustrate real customer experiences than by longevity in the industry and company growth. That’s why I read through dozens of SunRun reviews — and hundreds over the past few years — to see what customers actually think of working with the company. Based on my findings, customer experiences can vary. Positive reviews mention things like good communication, fast responses to warranty claims and systems that perform in line with what the company estimated in the contract. Negative reviews mention issues with slow warranty claim responses, a lack of communication and misrepresentations made throughout the process, specifically when it came to solar incentives and energy consumption offset.

It seems like the use of third-party installers is what leads to some variance in what you can expect from SunRun, which is unfortunate. I’ll include two reviews below at both ends of the spectrum to paint a picture of what you might experience if you choose SunRun.

“We installed our system in January of 2023. We noticed in July that the system was not producing what it’s supposed to, and so we were getting ready to call customer service. Before we could, [they] called us to make an appointment for maintenance to come out and look at our system. They arrived right on time and not only solved the problem of the system not communicating with Sunrun because of Wi-Fi being down, but also noticed a problem with the inverter, and the service person is going to come back again to fix it and will also arrange for us to get a credit for the lost usage. I believe this is outstanding service in a proactive manner that makes us feel very happy that we went with Sunrun.” — Janet S. via BBB

“Terrible experience. [First,] the solar panels broke and they didn’t even tell us. Then we had a roof leak. Their scheduling and project management team is abysmal. It takes hours to get through the meandering call tree and transfers between departments. The different departments don’t communicate well. It’s been over a year with half the panels stacked in the yard and the roof torn up. Roofers come out to fix it but don’t do it.. It’s weeks or months between each team’s appointment. Avoid this company.” — Shawn via TrustPilot

SunRun Customer Service 

4/10

Customer review scores don’t always tell the complete story when it comes to customer service, as some customers complain about marketing and sales tactics that, while potentially shady, don’t indicate that you’ll have problems with your installation or warranty claims. That’s why I read through SunRun reviews to find a pattern of complaints and problems that could actually affect your experience.

I deducted quite a few points from SunRun because it really does seem like you get the luck of the draw when it comes to the local installer SunRun assigns to your solar project. There are enough complaints about communication and repairs that should be covered that go unaddressed that I couldn’t give SunRun a higher score for customer service. SunRun has also been the target of class-action lawsuits for deceptive marketing, which means you really need to educate yourself before going solar with SunRun to ensure you get a system that will actually serve you well and save you money. I always prefer companies that are upfront and honest and make a good name for the industry as a whole by putting customers first.

Why We Chose Palmetto Solar

Palmetto Solar is another company I’d seriously consider if you know you want a solar lease for $0-down solar. Palmetto’s lease comes with one of the best production guarantees available — up to 95% of the estimated energy generation — a comprehensive 25-year warranty that keeps your leased system totally protected and a buy-out option after the first 5 years. This buy-out option is the only one I’ve seen from any provider, and it gives you the low upfront cost benefits of a lease with the potential for the long-term benefits of a cash purchase, all in one package.

Palmetto Solar is lacking when it comes to the add-on equipment and services available, but it’s a solid company if you just want the basics. Plus, Palmetto scores higher in our ratings when it comes to company reputation than all of the other companies in our rankings, with the only exception being All Energy Solar. That means Palmetto offers greater peace of mind than most competitors that your system will last and continue saving you money for many years to come.

What I Like About Palmetto Solar

The most appealing aspect of going solar with Palmetto, in my opinion, is the buy-out option for leases. Customers who can’t swing a cash purchase or loan can go solar now for no money down and then have the opportunity to switch payment plans after 5 years, giving you the best of both worlds.

Palmetto includes a roof leak warranty with all of its installations, which helps insulate you from issues related to the above-average rainfall and snowfall in Massachusetts. For even greater protection, you can also opt into the Palmetto Protect program, which includes one of the best performance guarantees in the industry. This helps ensure that you avoid paying the above-average price for electricity from the grid due to an underperforming solar array.

What I Don’t Like About Palmetto Solar

Palmetto falls a bit short when it comes to its add-on products and services, so unless you want a simple panel-only system, it’s probably not the best option for you. It doesn’t install solar batteries or any energy efficiency upgrades like SunRun does, and it also doesn’t tackle roof repairs and replacements, so you’ll need to go through a third party if you need roof work done before installing your panels.

Palmetto’s workmanship warranty is half the industry average at just 10 years, and although the installers are NABCEP®-certified to help ensure a professional installation, I’d prefer to see the company standing behind its work for longer. Palmetto also uses third-party installers to carry out the labor, so you could run into problems with getting one of the companies to own up to mistakes if you do find issues with your installation.

Palmetto Solar Installation Process and Timeline

Getting solar installed through Palmetto is likely going to take weeks or even months, according to the company’s website, but it doesn’t give specific time frames. I’d expect the typical timeframe of between 6 and 8 weeks, but you could wait longer if there are unexpected delays, like long wait times to get permits approved. Keep in mind that there’s always a chance that the use of third-party installers will lead to delays and miscommunication, as well.

The actual process Palmetto follows is standard. You’ll have an in-person inspection, during which your rep will measure your roof, assess shading and sun exposure and evaluate your energy demands. The Palmetto team will then design your system and send it to you for approval. Once you sign the contract, the team will begin to pull permits and then send a third-party installation company to complete the installation. Palmetto will then schedule final inspections before activating your system.

Palmetto Solar Standard Services & Financing 

17/25

Palmetto has outstanding financing options, but its services leave a little to be desired. It contracts out installations to local installers, which leads to the company losing points in our rankings. Introducing third parties can complicate the process and potentially cause delays with the installation and even repairs and replacements that are covered under warranty.

Palmetto doesn’t install batteries, which is only a minor downside in Massachusetts right now, in my opinion. I don’t recommend batteries in the Bay State because they add an average of $10,000 to your system costs, and since Massachusetts has one of the best net metering policies in the country, they generally won’t increase your long-term savings at all. However, net metering programs are declining across the country, so I do hope Palmetto adds the option for on-site storage to its services in the future, as I expect it to be a necessity if and when Massachusetts follows suit with states like California, which recently decreased the credit rate for excess energy production by around 75%.

Palmetto has its own mobile app that gives you information about your system production and energy consumption in real time, as well as access to a payment platform to make paying for your solar easier. The ability to monitor your system is nice to have in the sense that you can keep better track of consumption and make educated decisions on how to decrease your electricity usage. More importantly, it allows you to identify system issues early if production dips, which can save you money if that early detection gets your system back up and running quickly.

Cost and Financing Options

Palmetto accepts 3 of the 4 major payment options, including cash, loans and leases. I suggest a cash purchase if you can make it work because this will avoid you having to pay interest on a loan, which typically cuts into your net savings by around $5,000. You’ll see the highest savings overall with a cash purchase: an average of $37,303 in Massachusetts as compared to $32,000 with a loan or just $5,000 with a lease. Paying in cash will also raise your property value, and it lets you take the federal tax credit, an average potential value of over $7,250 in your area. Cash payments are the least accessible option, though, as you’ll be on the hook for an average of $24,180 before incentives.

Solar loans drastically bring down that upfront payment — usually to a few thousand dollars in a downpayment — and make solar far more accessible. Loans still come with the benefit of boosting your property value and letting you take the ITC, and they are generally less likely to complicate the sale of your home if you move than a lease is. However, you will pay more for your system overall because of the interest, so expect around $5,000 to be tacked onto your total cost over time, which decreases your net savings.

I don’t recommend solar leases in most cases because they deliver the lowest savings over the life of your system — an average of just $5,000 — they don’t let you take the federal tax credit and they won’t increase your property value. If you sell your home before the lease is up, you’ll also either need to pay an early cancellation fee or make sure the new owner is willing to assume the lease payments.

However, leases do have the major benefit of requiring no money down, making them the most accessible option overall. If you lease through Palmetto, you have the benefit of $0 down in addition to a buy-out option to switch to a solar loan or cash payment after 5 years, giving you the benefits of both ownership and rental.

Palmetto Solar Extra Services Offered 

2/5

Palmetto seems to focus most of its efforts on core solar installations — panels and inverters — so it loses some points in our ratings when it comes to its additional services offered. It does install EV chargers, which I think is a nice option to have now but will become more important in the near future. Massachusetts is following in California’s footsteps, as it’s requiring that all new light-duty vehicle registrations in the state be for ZEVs as of 2035. That means the popularity of chargeable cars will spike, and the need for at-home charging capability will also increase. Getting an EV charger from Palmetto now can “future-proof” your system, and you’ll be able to take the ITC for the cost, which can effectively reduce the cost by 30%.

Palmetto also offers company monitoring for its systems via its Palmetto Protect program. You get what the company calls “intelligent issue detection” as well as alerts if your system isn’t producing as it should. This is helpful regardless of where you live because it gives you peace of mind that your investment is protected. It’s especially useful in areas like Massachusetts, though, where the cost of electricity from the grid is well above average, and early issue detection can help insulate you from out-of-pocket costs if your system would otherwise stop producing.

Palmetto doesn’t handle roof work, so if you need replacement or repair to make rooftop installation worthwhile, you’ll need to coordinate with a different company. This requires a bit more work on your part, and it could potentially lead to finger-pointing if there’s an issue and both companies believe the other is responsible.

Palmetto also doesn’t offer any energy efficiency upgrades, like smart thermostats, HVAC upgrades or new windows and doors. This isn’t a huge deal if you don’t need these services, especially since Massachusetts homeowners already use far less electricity than most U.S. residents. However, I do like to see solar providers offering efficiency upgrades, as it makes them more of a one-stop shop for combatting rising prices for power.

Palmetto Solar Environmental Impact & Sustainability Practices 

7.5/10

Converting your home to solar is one of the best ways to reduce your carbon footprint, and it will absolutely have a positive impact on the environment. However, I still think it’s important to choose equipment brands and installers who do their part to better the environment, too. I assess each provider based on the panel brands they install and the overall sustainability of those manufacturers.

Palmetto installs REC and QCells panels, both of which tie for the best solar panels in the industry for sustainability. Both companies use recycled materials during the manufacturing process, and both have end-of-life (EoL) recycling programs to keep their used products out of landfills. They lose some points because neither is manufactured primarily in the U.S., but neither have documented issues with slave labor, child labor, dangerous working conditions, low pay or racism in the workplace.

Palmetto Solar Equipment Quality & Reliability 

17.85/25

The average cost of a solar array in Massachusetts is around $24,180 before incentives, so every homeowner will undoubtedly want to know that their investment is protected. I do a deep dive into panel specifications for each solar installer to see how the brands each offers stand up to the rest in terms of durability and long-term performance. I look at 18 specifications for each manufacturer, but there are 3 that stand out as most important in Massachusetts, in my opinion.

First is the panel efficiency. Higher efficiency ratings mean more electricity generated for your home and a lower chance of you having to pay to pull power from the grid, which costs about 170% more in Massachusetts than the national average. Anything at or above 22% is ideal. The REC and QCells panels Palmetto offers have efficiency ratings up to 22.6% and 22.0%, respectively, so both should suit you well in the Bay State.

Second is the panel degradation. All panels lose efficiency over time, and panels with above-average degradation rates are more likely to leave you paying for electricity from the grid sooner. Most panel manufacturers guarantee between 85% and 92% remaining efficiency after 25 years, and REC and QCells both fall above 90%.

Third is the max snow load, which tells you the force your panels can withstand from accumulating snow before sustaining damage. This is especially important in Western Massachusetts, where snowfall can be double the national average. The average snow load rating among tier-one panels is 5,870 Pascals. REC panels are above that at 7,000 Pascals, and QCells is the industry leader at 8,100 Pascals.

Warranties and Guarantees

It’s also important to look at the warranty coverage you get for the equipment from your manufacturer and for the labor you get from your installer. There are 4 types of solar warranties I recommend looking for before committing to a provider.

First is the equipment warranty, which comes from the manufacturer and covers malfunctions related to product defects. Most manufacturers include a 25-year equipment warranty, and both REC and QCells panels from Palmetto match this.

More important, in my opinion, is the performance warranty. This also comes from the manufacturer and tells you your panels’ maximum degradation rate over the warranty term. I think this is especially important in areas where electricity costs are above-average, like Massachusetts, because they can help prevent having to pull from the grid and pay for power over time, bumping up your savings. The standard warranty guarantees between 85% and 92% efficiency after 25 years. REC guarantees 92%, and QCells guarantees 90.58%, both of which are outstanding.

Next, I look at the labor warranty. This comes from your installer and guarantees that the installation process won’t cause damage to your panels. I think this is also critical in Massachusetts because the above-average rain and snowfall can more quickly expose the types of covered issues than in other states. The average workmanship warranty lasts for 12 years. Palmetto only includes a 10-year labor warranty, so it lost points in our ratings accordingly.

Finally, I look for roof leak warranties. These are, arguably, the most important because they protect your roof and your home from water damage related to the roof penetrations your installer makes to install the panels. Most companies don’t include a roof leak warranty, but I’m happy to report that Palmetto offers one through Palmetto Protect that lasts for 5 years. With above-average rainfall and snowfall, this is great news for aspiring solar customers in Massachusetts.

Palmetto Solar Company Reputation 

21.5/25

There are close to 200 solar installers in Massachusetts alone, and I’ve researched a lot of companies that seem great on the surface but don’t have the reputation to back it all up. Thankfully, Palmetto isn’t one of those, and the company scores quite high in terms of how the company is viewed by customers. First off, Palmetto was founded in 2010, and I award maximum points for company experience for anything over 10 years. Some companies come into the solar space only to find a few years later that the competition is too high. They go out of business, and they can take your warranty coverage with them. Palmetto’s longevity doesn’t guarantee this won’t happen, but it does suggest that it’s here to stay and that your warranties will continue to be honored.

Palmetto also maintains an A+ rating and a customer review score of 3.39 stars with the BBB. The average score in the solar industry is around 2 stars, making Palmetto a stand-out option for quality customer service.

The company also uses NABCEP®-certified installers, and since certification demands training above and beyond what’s mandated by the state, this suggests that you’ll get a professional installation that is less likely to cause equipment or property damage. Palmetto is also an SEIA member, which suggests that the company is invested in the industry, something I always like to see from installers.

Consumer Reviews and Testimonials

A big part of my company reputation analysis involves reading through customer reviews to see what real-world customers love and hate about each provider. Positive Palmetto Solar reviews mention things like timely installations, a sales process that isn’t aggressive or pushy and systems meeting the estimated production in the customers’ contracts. Negative reviews mention things like misleading marketing and salesmanship and delays in getting the system up and running. I feel that Palmetto’s use of third-party installers might be a big reason why some installations go smoothly and others don’t, so it seems like your experience will depend on the installer assigned to your project.

I’ll include one positive and one negative Palmetto Solar review below that I believe illustrate the best and worst you can expect from the company.

“Palmetto has kept me well informed about the project and the next step [throughout] the entire process. I am very happy with the end result. It did take a bit longer than I anticipated, but [it was] well worth it! Palmetto is always quick to respond to any questions. My solar panels are producing above my expectations. So happy I went with Palmetto.” — Kay G. via BBB

“I’m going to keep this short: I was promised 22,000 kWh a year, [but] I get 14,000 kWh a year. After a year, they still haven’t taken this tree down that they promised. Everything that the salesman said to me has been a lie. It should be a 0 star review.” — Alex A. via BBB

Palmetto Solar Customer Service 

8/10

The final metric in our company scoring is a subjective score that I determine based on the reviews I read through, the issues that stand out and a call I made as a secret shopper. The call was pleasant, and I spoke with a representative who was helpful and able to answer a few questions I had. It didn’t seem like an overly-aggressive sales pitch that I got, and I didn’t hear anything that seemed like a misrepresentation regarding solar incentives or savings.

I did deduct some points because some of the customer complaints I read through on the BBB mentioned that they were misled by salespeople in person. One or two comments like this could indicate an honest misunderstanding, but it seems like there’s a pattern here. I can’t stress enough to read your documentation carefully and go into your sales appointment with some knowledge of what to expect. Thankfully, it seems like there are few issues with warranty claims going unresolved, and this, in my opinion, would be a much more severe problem.
