#2 ADT Solar: Best Solar Warranty


4.5/5 Overall Rating


ADT Solar designs and installs residential solar systems with equipment from top manufacturers and backs them up with an incredibly comprehensive 25-year warranty. ADT acquired Sunpro Solar in 2021, and it is now one of the top 10 solar companies in Florida. The aspect of ADT Solar that stands out within the industry is its warranty. ADT offers a comprehensive warranty that guarantees the solar system will produce at its estimated level for 25 years after purchase. However, it’s unclear which solar panels ADT Solar installs, which could significantly affect a homeowner’s power production. Luckily, customer support is available by phone or email to answer any questions. Customers of ADT Solar will also appreciate the company’s 24/7 solar monitoring that ensures a home’s panels are running properly at all times. The company’s solar installation technicians can also make roofing repairs before or during a solar panel installation. This can streamline the process and means that a homeowner doesn’t need to hire an additional contractor.
