What Are the Top 5 Solar Companies in Vermont?

The solar industry is booming across the country. Although it seems Vermont has had a slower start, its neighbors Massachusetts and New York are two of the top states for solar energy installations, and it’s only a matter of time before Vermont homeowners start capitalizing on the benefits of having a home solar energy system.

Below is an “at a glance” look at each of the top solar panel companies in Vermont, analyzed and ranked by the EcoWatch Solar Reviews team. You might find some popular solar installers like Vivint Solar aren’t included in our reviews, which is intentional due to issues like lawsuits and reports of poor customer service in Vermont. The companies listed on this page are reputable solar installers serving the Green Mountain State and beyond.

Note: The EcoWatch Ratings you see in the company snapshots at the top of this page reflect our overall assessment of the company, but our rankings reflect the best solar companies in Vermont, specifically. If you notice that a company lower on our list has a higher EcoWatch Rating, it’s likely because it’s a great company but there are better installers for this specific area.

1. SunCommon

Headquartered in Waterbury, SunCommon is Vermont’s largest solar installer. EcoWatch awarded SunCommon first place on our list of the best solar companies in Vermont because it’s a forward-thinking Benefit Corporation (B Corp) that’s transparent about its impact and progress in building energy-efficient systems. The company claims the carbon emissions it saved by solar in 2020 is equivalent to planting 200,000 trees.

SunCommon doesn’t just have a great reputation for social impact and environmentalism. It offers some of the best solar panels on the market, a wide range of solar services and excellent reviews from customers.

Pros for SunCommon

  • Excellent social impact and transparency, with B Corp certification and emphasis on environmental benefits
  • Wide selection of the best solar panels, including LG, SunPower, Green Mountain, Tesla and more
  • 20 years of experience in Vermont, so it’s familiar with local incentives, weather and utility policies

Cons for SunCommon

  • Expensive
  • Doesn’t offer solar leases or power purchase agreements (PPAs)

Brands of Solar Equipment Offered LG, SunPower, SolarEdge, Green Mountain, IronRidge, Tesla
Financing Options Cash, loans

2. SunPower 

SunPower has remained one of the top solar installers since 1985, and there are few — if any — solar companies that can hold a candle to its long-standing reputation. Aside from having excellent warranty coverage and the most efficient solar panels on the market, SunPower reportedly has outstanding customer service.

SunPower offers personalized solar energy system designs and uses its own name-brand products for everything, including solar panels, inverters and batteries. That guarantees that the products will work in sync and are all protected under one in-house warranty, unlike many other solar installers that will offer different warranties from the installer, panel brand, battery brand, etc.

Pros for SunPower

  • Most efficient solar panels on the market
  • All aspects of the system are covered under one all-inclusive warranty
  • Sleek systems designed to work in synchrony

Cons for SunPower

  • Most expensive solar panels on the market 
  • Not local to Vermont, therefore the quality of installation and service will depend on the certified SunPower dealer closest to you
  • Limited selection of solar brands (only offers SunPower products)

Facts and Figures: SunPower

3. Green Mountain Solar

Green Mountain Solar is another great local option, headquartered in South Burlington, Vermont. Green Mountain was launched as an affiliate of the successful Granite State Solar based in New Hampshire and has a stellar reputation in New England, as well as a wide selection of solar energy brands and above-average warranty coverage.

There are several benefits to choosing a local provider for your solar project, including a lasting relationship long after the sale (which is helpful if there are any issues post-installation). Green Mountain will also have a stronger familiarity with local weatherization needs and solar incentives, as well as more prompt and personalized service compared to national providers.

Pros for Green Mountain Solar

  • Great local provider known for prompt and personalized service
  • Excellent selection of the best solar panels and batteries
  • Above average warranties, including 25-year production and 12-year workmanship coverage (compared to 10-year industry standard)

Cons for Green Mountain Solar

  • Limited experience in Vermont compared to competitors (founded in 2017)
  • While we don’t recommend solar leases or PPAs, some homeowners may consider it a con that Green Mountain doesn’t offer these options

4. PlugPV

PlugPV was once a company that would provide local installation services for national solar companies. After over a decade of sales and installation experience, PlugPV became its own solar installation company in 2017, priding itself on its workmanship, quality and experience. 

PlugPV is headquartered in Albany, New York, but is well-vetted in Vermont with most of its installs in the Northeast. The company has received great feedback from customers, plus it offers a broad range of services, including panels, batteries, EV charging stations, community solar and roofing. All of that, paired with solid warranty coverage, landed PlugPV a spot on our list of the best solar companies in Vermont.

Pros for PlugPV

  • Broad range of services with high-quality workmanship 
  • Regional company with large resource base, headquartered near Vermont (Albany, NY)
  • Good selection of brands including LG, Q Cells, Tesla and IronRidge

Cons for PlugPV

  • Although PlugPV has experienced employees, the company itself only has five years of experience
  • Does not offer solar leases or PPAs
  • Low BBB rating

5. Catamount Solar

Catamount Solar is a local, employee-owned company with more than a decade of experience in Vermont. Catamount has made an outstanding impact on the Vermont community, allocating 5% of its annual profit to support community and environmental programs initiatives. Additionally, Catamount has an excellent reputation and affiliations with the NABCEP, the Solar Energy Industries Association (SEIA), Renewable Energy Vermont, Efficiency Vermont and more.

Aside from being a reputable clean energy provider, Catamount also has an above-average 15-year workmanship warranty and a good range of products, including some of the best and most affordable solar panels. Catamount also partners with Vermont State Employees’ Credit Union (VSECU) and its VGreen loan program to offer financing rates as low as 1.99%.

Pros for Catamount Solar

  • Local company with 10+ years of experience
  • Gives 5% of annual profit to support the community 
  • Above-average 15-year workmanship warranty

EcoWatch Criteria for Selecting the Top Solar Company in Vermont

The EcoWatch Solar Reviews team sifted through all of the solar power installers in Vermont to find the best solar companies near you. Our EcoWatch Rating comes from a score that combines the categories listed below. You can visit our methodology page for more information on how we reviewed these companies.

Warranty

Solar photovoltaic (PV) systems are costly, which makes a reliable warranty even more important to have. Especially in states like Vermont, where severe weather conditions are possible. Solar installers almost always provide some kind of warranty to cover either equipment, labor or both. Here’s a quick explanation of solar warranties and the minimum lengths we look for:

  • Product warranty (also called manufacturing warranty): This covers each specific part of the solar panel system in case of defects. The industry standard is 25 years.
  • Workmanship warranty (also called labor warranty): This covers the design, assembly and installation of your system (think roof leaks, faulty wiring, etc.). The industry standard is 10 years, but the best companies offer 25 years.
  • Performance guarantee (also called output guarantee): This ensures your system produces the amount of energy projected in your solar proposal and contract. For example, a company might guarantee that your system will still produce at 90% capacity by year 10, 80% by year 20 and 75% by year 25. The best companies offer 25-year performance guarantees.

While nearly all solar installers offer warranties, our team tends to favor companies that match or beat the industry standard.

Year Founded

Clean energy alternatives are becoming increasingly popular in Vermont, which entices newer solar companies with less experience to try to capitalize on the market. EcoWatch takes the year a company was founded into account when looking for the best companies because we want to recommend those with proven track records. Plus, your solar warranty is only valid if the company you choose for your solar system installation is still in business, so you want to be confident in both the history and future of the company.

Services Offered

Going solar involves a lot more than sticking some solar panels on your roof. Depending on your area and your household’s specific needs, you may need a specialty solar service. For example, if you live in an area prone to power outages, you may prioritize backup battery solar power storage. Or if you have a flat rooftop, you may need a solar installer that offers a ballasted array mounting system. For this reason, a solar installation company that offers a variety of services is going to get a higher EcoWatch Rating.

Brands of Solar Equipment Offered

Just as you may need a specific solar service, you may also need (or want) a specific brand of solar equipment. EcoWatch takes the range of brands offered into account when scoring a solar company because we want to highlight companies that have the most to offer our readers. However, we may have picked some companies that only have a few installers because the brands they do carry happen to be the most efficient solar panels (SunPower) or the cheapest solar panels (Q Cells) or what have you. Same goes for homeowners who may want a specific brand, such as a Tesla Powerwall — not all companies sell those.

Industry Affiliations

Here at EcoWatch, certain solar industry affiliations tell us whether these companies are reputable or whether they’re looking to earn a quick buck. Companies that are affiliated with the Solar Energy Industries Association (SEIA), North American Board of Certified Energy Practitioners (NABCEP) or hold a B Corp title are usually more serious about offering solar solutions for the good of the planet, not just for profit.

Size of Company

There are pros and cons to choosing a bigger solar company over a small, locally-owned solar company. EcoWatch takes the benefits and faults of company size into account when evaluating the top solar companies in Vermont.

Larger solar companies often have better deals than their local competition because they can buy their solar equipment in bulk and often have more resources at hand. However, they tend to lack when it comes to customer care and local knowledge about solar incentives and rebates. On the other side, a smaller solar company might be more expensive and could take more time for the installation process. But they’re more likely to deliver top-notch customer care and expedite your connection to the power grid for things like net metering if they have relationships with the local utility companies.

Solar Pricing and Financing

While you’re likely to see major savings on your electric bill, switching to clean energy is a large upfront investment. That’s why we tend to favor companies that offer the best solar pricing and financing options. We evaluate each company based on the affordability of its solar panel installations, considering what it offers in terms of loans, solar leases, and power purchase agreements (PPAs). The more options the company offers, the higher the score it receives.
