Overview: ADT Solar Vs. Trinity Solar

Together, ADT Solar (formerly Sunpro) and Trinity Solar cover over half the country, which means countless homeowners will likely be considering one or both of these companies for their rooftop solar panels. 

We’re providing insight into which company we believe is better so you’re more likely to be pleased with your decision.

Company Brand Is Best For Price Warranty Coverage States Served BBB Rating Payment Options Solar Services Offered
ADT Solar Warranty Coverage and Affordability $$$ 25 years for equipment, production, and workmanship 23 states (expanding to 5 more) B+ Cash, loan Solar panels, solar energy storage systems, EV chargers, solar monitoring
Trinity Solar Positive Customer Experience $$$ 25 years for equipment and 5 years for workmanship 9 states A+ Cash, loans Solar panels, solar battery storage, EV chargers, solar monitoring

ADT Solar (Formerly Sunpro) Overview

Sunpro was a nationally recognized brand that is now known as ADT Solar. It serves 23 states and has a reputation for affordability and good quality equipment.

Sunpro was founded in 2008 and was purchased by ADT — the home security company — in 2021.

Now working under the name ADT Solar, Sunpro is one of the best solar companies for warranty coverage.

Trinity Solar Overview

Trinity Solar started as a family-owned HVAC company in 1994 and made the switch to installing solar panels in 2004.

As a company dedicated to quality service from the get-go, Trinity still manages an in-house installation team that delivers quality and professionalism to all of its customers.

Trinity is predominantly active on the East Coast, and its service area is much smaller than ADT Solar’s. However, the company is still growing.

Cost Comparison: ADT Solar Vs. Trinity Solar

The cost of your solar equipment will always be an important thing to think about, especially when it comes to choosing an installer. Every company varies in pricing, so looking at each provider’s average costs or getting free quotes from all candidates is a good first step.

Costs & Financing Options

Prices vary among installers primarily because of the equipment they offer. Some companies install high-efficiency and high-quality equipment that comes with a lengthy product warranty. 

These brands typically cost more upfront, although long-term savings can be higher due to greater savings on your electric bills.

The financing options offered by your solar panel company can have an impact on your costs as well. Those that only offer cash purchases and solar loans will cost more upfront but will often cost the least in the long run. 

Solar leases and power purchase agreements (PPAs) cost very little — if anything — upfront but save you the least over time.

Which Company is Cheapest, ADT Solar or Trinity Solar?

Sunpro (ADT Solar) installs solar equipment manufactured by LG and Panasonic. These panels are tier-one options that are quite efficient and will meet the energy usage of most homeowners in a moderately-sized solar power system.

Trinity Solar doesn’t specify which solar equipment brands it installs. However, customer reviews suggest that the following, including some low-profile options, are available:

  • Qcells
  • Panasonic
  • LG
  • SunPower (Maxeon panels)
  • SolarEdge
  • Enphase (inverters and microinverters only)
  • Tesla Solar (Tesla Powerwall batteries and panels, but not Solar Roof shingles)

These panels are also high-quality, monocrystalline options that should serve all homeowners well and meet energy needs. They’re about on par with ADT Solar’s options in terms of energy efficiency and price.

Our Pick for Best by Cost – ADT Solar

ADT Solar and Trinity both come at about the same price, which hovers around the national average. Both provide about the same quality photovoltaic equipment. 

However, Trinity only takes cash and solar loans, while ADT Solar accepts cash purchases, loans, solar leases and PPAs, so ADT Solar will be a bit more affordable in some cases.

Trinity and ADT Solar offer more information about their financing options in the FAQs and other sections of their websites.

Warranties Offered: ADT Solar Vs. Trinity Solar

The warranty coverage you get with your solar equipment is essential for protecting your investment and ensuring that your panels continue to produce energy as expected. Warranties typically cover equipment damage, issues resulting from installation or power production. Some of the best warranties cover all three.

sunpro vs trinity solar

Sunpro Solar — operating as ADT — is known for having one of the best warranties in the solar industry. It covers virtually all issues you might have with your solar power system, including equipment damage, efficiency and workmanship for an impressive 25 years.

Trinity Solar provides no production guarantee, but it does offer a 25-year warranty for equipment damage and a five-year workmanship warranty.

Our Pick for Best Warranties – ADT Solar

ADT Solar clearly has superior warranty coverage. Trinity Solar’s protection plan is decent, but it pales in comparison to ADT Solar’s.

Coverage Area: ADT Solar Vs. Trinity Solar

Most solar companies operate only in certain states, so it’s a good idea to check a company’s footprint before you do too much research on its products and services.

ADT Solar is one of the largest solar companies in the country, and it serves a massive area of 23 states. These include:

  • Arizona
  • Arkansas
  • California
  • Colorado
  • Florida
  • Georgia
  • Illinois
  • Iowa
  • Kansas
  • Louisiana
  • Maryland
  • Mississippi
  • Missouri
  • Nebraska
  • Nevada
  • New Mexico
  • North Carolina
  • Ohio
  • Oklahoma
  • South Carolina
  • Tennessee
  • Texas
  • Virginia

The company is also working on expanding into five more states, including Indiana, Massachusetts, New Jersey, New York and West Virginia.

Trinity Solar is a regional company with a much smaller service area. It provides solar panel installation services in the following nine states:

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

Our Pick for Best Coverage Area – ADT Solar

Once again, ADT Solar is the clear winner in terms of coverage area, with more than double the states served compared to Trinity Solar.

Solar Panel Performance: ADT Solar vs. Trinity Solar

Many solar customers don’t give a thought to solar panel performance and assume that all brands are similar. Unfortunately, that’s not the case, and how well your panels perform dictates the following:

  • How many panels you need for your home energy requirements
  • How expensive your solar power system is
  • How much electricity your solar energy system produces
  • Your long-term savings on bills from your utility company
  • How much net metering will benefit you

The specific efficiency rating varies between ADT Solar and Trinity, depending on which of the offered brands you install. However, all of them are relatively close in efficiency and are considered some of the best in the industry for power production.

Our Pick for Best Panel Performance – Tie

The panel performance you experience with ADT Solar’s and Trinity Solar’s equipment will be about the same. You’ll have to use other metrics to figure out which installer is best for your home solar project.

Customer Experience: ADT Solar vs. Trinity Solar

Finally, the customer experience offered by a solar installer will play a major role in how pleased you are with your solar system and the installation overall. More importantly, though, it can dictate how quickly issues get responded to, which has an effect on how much your panels save you on your energy bills.

Below, we’ll discuss the service you can expect from ADT Solar and Trinity and help you decide which is a better fit for you.

What Customers Say About ADT Solar (Sunpro)

Sunpro/ADT Solar is now a large company that spans nearly half the country. While it uses a team of in-house installers to help maintain good customer service, its size can also mean some issues with responsiveness. Customer complaints often include comments about:

  • Slow responses to customers, especially after the solar installation process
  • Delays in getting warranty claims addressed
  • Communication breakdown between salespeople and installers can lead to delays in installation and issues with scheduling

Sunpro/ADT Solar still has plenty of positive customer reviews, though, so your experience can vary a bit. Many people are pleased with the service they receive and how thorough and helpful the crew is throughout the entire process.

Below are some reviews for Sunpro that we found online.

“This company gets stuff done! It is a bit of a process getting solar panels, but once the final inspection is complete, the electricity bills are drastically reduced. Plus, their referral program is amazing and they keep you up to date through the entire process. Highly recommended!” — Phil H. via Better Business Bureau (BBB)

“Worst decision ever to go with Sunpro/ADT solar. Liars. They lied about almost everything. [They] clearly said it was a 10-year loan. I trusted too much. It’s a 20-year loan. They said payments wouldn’t start until the solar system was operational. I paid on the loan five months before it was operational. They said it would basically wipe out energy bills. [It] does not… I was supposed to be able to monitor the system online but was never shown how.” — Caleb H. via BBB

What Customers Say About Trinity Solar

Trinity Solar is a much smaller company, and it has a reputation for better customer service. Many of the positive customer reviews for this company include comments about:

  • The technicians’ willingness to help take advantage of local solar incentives, including the federal solar tax credit
  • The professionalism of the installation team
  • How well-informed the salespeople are
  • How helpful the sales process is without being overbearing

Although Trinity is smaller, it still runs into some issues with customer service. Some homeowners have issues with response times, delays in the installation process, and delays in addressing warranty claims.

Below, we’ll include a positive and negative review to give you an idea of the kind of service you might get from this company.

“Trinity Solar did everything they were supposed to do on time and without any mistakes. They cleaned up properly. Not that there was much to clean up anyway. The work inside the attic was neat and out of the way completely. No loss of space. My monthly bill is exactly what they said it would be. I am overproducing electricity. They also paid me three $1,500 checks for referrals. They are a very reputable company. Highly recommended.” — Mark M. via BBB

I had solar panels installed by Trinity on my house and had a relatively good experience. However, I talked my parents into doing solar on their house and it has been an ongoing project for almost a year. It started in May 2020 and is still not completed as of April 2021. Trinity has not been very good at getting back to me and explaining why this is taking so long. I’ve made at least 20 phone calls and talked to different people and have not yet solved this issue.” — Joseph B. via BBB

Our Pick for Best Customer Experience – Trinity Solar

Neither of these providers is the best solar company if you’re looking for a positive customer service experience from the consultation to long after the installation. However, we have to go with Trinity Solar for overall customer service, as it has a reputation for providing better customer support.

Final Verdict: ADT Solar (Sunpro) vs. Trinity Solar

Both of these companies are good options if you’re planning on installing solar panels on your home. We would recommend ADT Solar over Trinity in most cases. The table below provides a quick look at how these companies compare.

Our Top Pick: ADT Solar

Overall, we’d recommend Sunpro — ADT Solar — over Trinity Solar for most customers. ADT Solar has far superior warranty coverage and a much larger service area. Although Trinity has a better reputation for customer service, we think ADT Solar is an overall better value for the money.
