25-year power supply
-
A manufacturer's warranty refers to the promise that it will fix a solar panel if it's defective due to environmental or production issues. With a 25-year power supply, Solaria makes it easy for homeowners to install a solar system. The guaranteed power loss rate is as follows: -2% during the first year, -0.5% per year after that, and 86% of the original nameplate value after 25 years.
