Going solar usually costs thousands of dollars, so it’s imperative that the company you choose for your renewable energy conversion is reputable and reliable. Choosing the right company can mean great customer service and warranty coverage, while the wrong one can bring you headaches and frustration.

In this guide to choosing a solar panel installation company, we’ll compare Momentum Solar and Trinity Solar, two of the larger regional companies in the U.S. We’ll review which solar provider is preferable for different aspects of your solar conversion and which we recommend to homeowners for each.

Overview: Momentum Solar Vs. Trinity Solar

When going solar, many homeowners choose national or regional companies (as opposed to smaller local companies) for their reliability and affordability.

Along with companies like Sunrun, Palmetto Solar, SunPower, and Tesla, Momentum Solar and Trinity Solar are two of the larger regional companies in the U.S., so they’ll naturally be top picks for many homeowners. That’s why we think it’s important to compare them and help solar customers decide which is the best solar company for them.

Momentum Solar Overview

This company is best known in the solar industry for its customer service. Momentum Solar offers a concierge service, which allocates each solar project to a single point of contact to make communication as straightforward and clear as possible.

Momentum Solar has great warranty coverage to keep your solar energy system protected for many years after installation. It also installs top-of-the-line equipment.

Overall, Momentum provides outstanding value for money, with prices coming in around average but the quality of service sitting well above average. With over a decade of experience, it’s a great option for going solar.

Trinity Solar Overview

Trinity Solar is a slightly smaller regional company, but its reputation is just as impressive as Momentum. Trinity doesn’t have the same concierge service as Momentum, but since its inception as a family-owned HVAC company, it has maintained great customer service and communication throughout and following the installation process.

Trinity Solar has less impressive warranty coverage than Momentum, and although it comes in around the same price, it doesn’t offer as many payment options.

Trinity has been serving solar customers since the early 2000s, so putting your trust in this company is a great option for many homeowners.

Cost Comparison: Momentum Solar Vs. Trinity Solar

Since photovoltaic equipment is so expensive, one of the first things most customers will look at when choosing a solar installer is the cost. In the sections below, we’ll explain why prices can vary among providers and how Momentum and Trinity compare in terms of pricing.

Costs & Financing Options

The average cost to go solar in the U.S. is $16,758 after the federal solar tax credit is accounted for. However, prices can easily range from around $11,000 up to $22,000 and beyond based on a few different factors.

One of the biggest reasons for the wide price range is the quality of the equipment being installed. There’s a huge variety of solar brands available, and they each come with different performance specs and durability ratings. Panels and solar batteries with higher efficiency or a longer lifespan will naturally cost more.

It’s important to note that higher-quality equipment tends to save you more on your energy bills in the long run, which means the higher cost is often worth it.

Labor charges can also vary among solar panel companies. The cost for the installation and preparatory work — including pulling building permits and connecting to the grid — can bring your total up or down by hundreds or thousands of dollars in some cases.

Finally, your payment method can affect your upfront and long-term costs of going solar. The most common payment options, with their upsides and downsides, include:

  • Cash purchases: Highest initial costs but leads to the greatest savings overall
  • Solar loans: Moderate upfront costs and provides the second-highest long-term savings
  • Solar leases and power purchase agreements: Little to no upfront cost, but the savings over time will be significantly lower

Which Company is Cheapest, Momentum Solar or Trinity Solar?

Neither Momentum Solar nor Trinity Solar makes the brands of equipment they install publicly available, so it’s hard to compare these installers based on equipment quality. However, based on customer reviews, it seems clear they both use tier-one panel brands and bring good efficiency and durability to the table to meet your energy needs.

On the surface, Momentum and Trinity are quite similar in their pricing, with both coming in at around the average for the areas served. Both provide free quotes for solar upgrades. However, Momentum accepts solar leases and PPAs, while Trinity does not. We don’t recommend these options to most homeowners, but they do make renewable energy accessible to more homeowners.

Our Pick For Best by Cost – Momentum Solar

These companies are about tied in terms of equipment pricing, and they bring a similar level of quality to the table. However, we have to give the win to Momentum Solar because it accepts more financing options to keep solar equipment available and affordable.

Warranties Offered: Momentum Solar Vs. Trinity Solar

Solar warranties are the best way to protect your solar power system and your investment in clean energy. They can cover solar product damage and malfunction, solar panel performance, and the workmanship involved in installing the solar energy system.

momentum solar vs trinity solar tip

Momentum Solar provides a 25-year warranty that protects the equipment and covers the workmanship. Along with that coverage, you also get between 10 and 25 years of protection from the manufacturer. Unfortunately, there is no performance guarantee offered.

Trinity Solar includes a similar 25-year warranty for the equipment and manufacturer defects. However, there is no power production guarantee, and the workmanship warranty is only good for five years.

Our Pick For Best Warranties – Momentum Solar

Although neither is the best solar company for peace of mind and system protection, Momentum Solar once again outperforms Trinity Solar when it comes to warranty coverage. Its workmanship warranty lasts for more than twice as long as Trinity Solar’s.

Coverage Area: Momentum Solar Vs. Trinity Solar

One of the first things you should consider when choosing a solar installer is the area it serves. This is an easy way to rule out companies that don’t operate in your state or city, which can save you time during your research phase.

Momentum Solar currently services 11 states, including:

  • Arizona
  • California
  • Connecticut
  • Florida
  • Georgia
  • Massachusetts
  • Nevada
  • New Jersey
  • New York
  • Pennsylvania
  • Texas

Trinity Solar has a slightly smaller footprint that encompasses the nine states below:

  • Connecticut
  • Delaware
  • Florida
  • Maryland
  • Massachusetts
  • New Jersey
  • New York
  • Pennsylvania
  • Rhode Island

Our Pick For Best Coverage Area

Momentum Solar is the clear winner when it comes to coverage, although it wins by a small margin. It serves two additional states at the moment. Both companies are in the process of expanding, so this could change at any point in the future.

Solar Panel Performance: Momentum Solar Vs. Trinity Solar

Many homeowners looking to go solar compare companies based on the pricing and customer service offered and never think about panel performance. However, the energy efficiency rating for your panels can determine how much energy your system produces, which affects your overall energy savings and how quickly your system pays for itself.

Unfortunately, neither Momentum Solar nor Trinity Solar is open about which solar panels, inverters, and microinverters it installs. Both use monocrystalline panels that fall into the tier-one category, but we can’t compare actual efficiency ratings accurately without knowing the brands offered.

Some solar reviews suggest that these installers use the best solar panels available for home solar systems. These include the options below:

  • Maxeon (panels from SunPower)
  • Qcells
  • Tesla panels and solar roof shingles
  • Enphase inverters and microinverters
  • Tesla Powerwall
  • Generac energy storage solutions

Based on customer reports, it seems clear that these companies are about equal in terms of panel performance and how well they accommodate energy usage. Many customers of both companies are pleased with how their solar power systems offset electric bills and provide energy savings in the long run, especially in areas where utility companies offer net metering.

Our Pick For Best Panel Performance – Tie

Since neither of these companies posts panel brands or efficiency ratings online, we can only rely on consumer reviews and feedback to determine performance. Based on the limited information, it’s safe to assume that these providers are about equal in terms of panel performance and solar system efficiency.

Customer Experience: Momentum Solar Vs. Trinity Solar

When it comes to installing solar panels, the impact of the customer service you receive extends well beyond your experience leading up to the installation.

Of course, it’s important to have a solar installation company that maintains communication throughout the process, but a responsive and responsible company is also more likely to respond to and address issues under warranty. This can save you thousands of dollars and loads of frustration in the long run.

In the sections below, we’ll include some information about how Momentum and Trinity treat their customers and what you can expect in terms of overall service.

What Customers Say About Momentum Solar

  • Professionalism and knowledgeability of the team

Below are some reviews we found online for Momentum Solar.

“Had an absolutely amazing experience with Momentum Solar. We got in contact about a month and a half ago and they were very informative about all the details. I was pleasantly surprised by their prices! They came exactly on time, did all their work within a few hours, and left leaving everything absolutely perfect.” — Mohammad Asaf via Google Reviews

“We were scheduled to have a rep come by and evaluate our home for solar. Shortly after the time of the scheduled appointment, no one had arrived and I called to confirm. After 10 minutes on hold, I was told that the appointment had been canceled because our roof does not receive enough sunlight. Momentum canceled the appointment but never called to inform me.” — Elizabeth Chubbuck via Google Reviews

What Customers Say About Trinity Solar

Trinity Solar also receives mostly positive reviews from customers, with many people commenting positively about the following:

  • Good communication from the free quote process through installation and beyond
  • Fast response times to warranty claims
  • Professionalism and knowledgeability of the team
  • Respect is shown by the in-house installation crew

No company of this size is without negative reviews, and Trinity Solar is no exception. There are some negative reviews that mention that the size of the company gets in the way of good customer service and efficient communication.

Some customers report being frustrated by the scheduling process and the intermittently slow response times to system issues and installation. Others complain about how aggressive the sales team can be.

Below are some customer reviews that illustrate what you can expect from Trinity Solar.

“So glad we switched to solar and used Trinity. [Our rep] was nothing but excellent in every [respect]… He let me know when [our town’s inspection appointments were] backed up and made calls to see if our inspection could be expedited. I even texted him with pictures to ask how to flip the switch on once permission to operate was given. He answered right away!” — Gina B via Better Business Bureau (BBB)

Disrespectful and annoying at best. Multiple Trinity agents have been soliciting and I have asked each and everyone not to come by as there was no interest. [My request] clearly can’t be respected. The last two reps were smug and found amusement in the fact that I was so irritated. When asked for supervisor information, he… wouldn’t give a contact number to his supervisor.” — Ken O. via BBB

Our Pick for Best Customer Experience – Tie

Both Momentum Solar and Trinity Solar have their pros and cons when it comes to overall customer service. Both solar energy companies provide a generally positive customer experience, and both maintain mostly positive reviews.
