Using solar power as a supplement or replacement for conventional electricity has become popular over the years, particularly in residential neighborhoods. With the cost of solar panel installation decreasing over the past 10 years and government incentives awarded to solar panel owners, solar energy has established itself as a viable alternative power source.

The This Old House Reviews Team is here to help you take advantage of this flourishing industry with in-depth research on the best solar companies in the United States.

Our Take on ADT Solar

ADT Solar offers comprehensive warranties and system monitoring to help support customers once their solar energy system is installed. Its transparent purchasing options and A+ rating from the BBB make ADT Solar a trusted provider for homeowners looking into solar.

We like the comprehensive 25-year labor and equipment warranty, plus the 25-year power production guarantee. We also like that ADT Solar offers three financing options and solar equipment from multiple well-respected manufacturers. Our primary concern with ADT Solar is the many negative customer reviews citing slow installation or improperly installed panels.

ADT Solar Services and Panel Options

ADT Solar sells monocrystalline solar panels, which have efficiency rates between 15% and 20% and an average life span of 25–40 years. Its panels are from some of the world’s most popular solar manufacturers, including Q Cells, Silfab, and Canadian Solar.

ADT also sells solar batteries and microinverters. 

  • Backup battery: A backup battery stores your system’s excess energy in case of a power grid outage or period of minimal sunlight. ADT Solar lets you customize your system with your choice of battery backup, including popular options such as the Tesla Powerwall 2 and the Enphase Encharge 10.
  • Microinverters: ADT Solar also sells Enphase inverters. These are what allow renewable energy to be converted into electricity directly at each panel. This helps you avoid higher costs and complications from a system that requires multiple cables and junction boxes.

ADT offers installation services for both panels and batteries. The company also has a roofing company, Buildpro, that helps you take care of installing a new roof and solar at the same time.

ADT Solar Installation Process

If you’re looking to integrate solar panels with your home’s electrical system, consider solar panel system installation from ADT Solar.

  1. Site assessment—To begin, ADT Solar will send a team of solar consultants to your home to determine if your home can support solar panels. Solar panels are most efficient when installed on a roof that’s facing south with little shade coverage. If your roof gets too much shade or has too steep of an incline, you may not be able to install a system.
  2. Design—ADT’s expert design team will work with you to create the ideal solar array for your roof and energy needs. 
  3. Permitting—Before your installation can begin, ADT Solar acquires the necessary permits that your municipality requires.
  4. Installation—Once your home is approved for installation, ADT Solar technicians install your selected solar panels and connect your system to the electrical grid. If you want to store excess energy collected by your solar panels, ADT Solar offers battery backup installation. 
  5. Inspection—ADT will work with a local building inspector to make sure your system is up to code. 
  6. System connection—Once your inspection is approved, ADT will turn on your system, and you can connect it to your local utility company’s power grid.

ADT Solar Reviews

ADT Solar is accredited by the Better Business Bureau (BBB), where it holds an A+ rating*. We read over 50 of the most recent customer reviews for ADT Solar and found that the company has many negative reviews from the last several months. Many customers report extended installation timelines and issues with workmanship. 

Here’s a sample of the negative and positive feedback customers have left about ADT, formerly Sunpro Solar:

“The panels were not installed to code. It took 8 months for ADT to come back and correct the deficiencies so the building department could sign off and I could receive permission to operate my system. So, for 8 months I was making loan payments while also paying full energy rates to the power company. In addition, their installers stained my carpet and left black finger prints on my walls and ceiling near the openings to my attic access.” — Peggy M., June 29, 2023, on BBB

Our salesman was awesome and super straightforward, didn’t sell us a pipe dream. We have not had an electrical bill over 13 Dollars yet. We are waiting on our state incentives and have already received our Federal Tax Credit. Great crew and sales staff. Communication took a day sometimes.” — Eydra C., March 20, 2023, on BBB

It took six months to get installed only to find out when we tried to turn them on that the whole system was wired incorrectly and not working. A month later they got it fixed however they never came back to install their energy package which was one of the key selling points. They dug a trench through my yard and didn’t replace the grass.” — Jeremy P., June 27, 2023, on BBB

Our last electric bill was $16.61. Basically, we have traded our electric bill for our payment on the solar panels, except that when the panels are paid for, we will own them, and still have very little to pay the electric company. The app on our phones is fun to watch as we can see how much electricity the panels are producing, and also how much electricity we are consuming.” — Sandra R., May 18, 2022, on BBB

ADT Solar Payment Options

ADT Solar provides three financing options:

  • Full purchase: If you can afford it, fully purchasing your system up-front comes with the most financial advantages. You’ll qualify for the federal solar tax credit, will own your system from day one, and won’t pay interest fees on a loan.
  • Solar loan: With a solar loan, you’ll pay a fixed monthly payment based on your credit score. This option also gives you system ownership and qualifies you for solar incentives. However, the loan’s interest rates mean you’ll pay more for the system in the long run. 
  • Solar lease: Leasing solar panels means you pay the solar company monthly for the system but don’t own it and don’t qualify for most solar incentives.

ADT Solar Warranty Options

ADT offers customers competitive warranty coverage on both equipment and labor. Most solar companies offer a 10-, 20-, or 25-year warranty. ADT Solar provides a 25-year warranty and performance guarantee. 

Here’s a breakdown of coverage with ADT:

  • 25-year labor guarantee on workmanship 
  • 25-year power production guarantee that states if your system does not produce the amount of energy guaranteed, you’ll receive the difference in cash
  • 25-year panel performance guarantee to cover any other issues that may arise with your panels 
  • 25-year Enphase microinverters guarantee to cover any issues that may occur with your system’s Enphase microinverters

Is Solar Worth It?

If you have a suitable property, installing a solar panel system is absolutely worth it, both financially and environmentally. Benefits include:

  • Renewable energy: Solar energy is a natural, infinite resource. 
  • Lower energy bills: Sourcing some or all of your home’s electricity needs from solar panels instead of your local utility company’s power grid saves electricity bill costs. 
  • Increased home value: Solar systems can increase home value. 
  • Reduced environmental impact: Opting for a renewable energy source reduces your carbon footprint and is a more sustainable way to power your home. 

You’ll benefit from going solar if:

  • Your property gets plenty of sun exposure
  • You live in an area that uses net-metering
  • You have high utility bills
  • You qualify for solar incentives that can save you money

Solar Incentives and Rebates

Most states offer solar incentives and rebates to help buyers save money on their solar power systems. While this varies by state, common incentives include:

  • Property tax exemption: Participating states waive the additional property taxes associated with a solar panel system. 
  • Sales tax exemption: Some states waive sales tax on solar equipment. 
  • Federal solar tax credit: The federal government allows those who own their system to claim 30% of the total system cost on their taxes the year of installation. Note that this requires system ownership, so only those who purchase their system outright or through a solar loan qualify. 
  • Net-metering: Net-metering is a program that allows you to sell any excess energy your system generates to your local utility company.

Our Conclusion

ADT Solar has several selling points. Its warranty is one of the market’s strongest and it offers a wide selection of solar products from reputable manufacturers. We also like that the company can provide roof repair services so both projects can be taken care of at the same time. 

We are concerned about the high number of negative customer reviews pointing to poor service and workmanship. We suggest doing further research into customer feedback on review sites and asking your local ADT Solar company for location-specific testimonials and references. 

Before deciding on any company to handle your solar project, we recommend thoroughly looking at a provider’s website, warranty, customer reviews, and reputation. Get an online estimate from at least three companies to compare pricing before making your purchase.
