All panel manufacturers warranty their products and provide a guarantee of energy output. Depending on the manufacturer and model, a typical warranty is 10 to 12 years and energy output is guaranteed for 25 years. Inverter warranties range from 12 to 25 years depending on the manufacturer. Most batteries carry a 10-year warranty, and solar installers usually warranty their work as well.
In addition to manufacturer warranties, Powur offers SolarInsure end-to-end insurance on the solar energy systems that we sell. SolarInsure’s policy offers 30-years extended warranty protection that covers 100 percent of the parts and labor associated with the manufacture, delivery, and installation of panels past the manufacturer’s warranty with no deductible.
