SunPower Back Contact 40-Year Warranty
Welcome to the solar industry’s longest and most comprehensive warranty. It’s as exceptional as our quality solar technology.
And since our back contact warranty covers the panel and its performance, it’s much easier to process than standard warranties in the unlikely event that you will need it. We also include broader coverage for panel repair and replacement compared to other warranties. Service availability varies by country and installation provider.
The 40-year warranty on our back contact panels is one more way we make life better with solar.
