SunPower Maxeon Panel
40-Year Warranty

Welcome to the solar industry’s longest warranty: the SunPower Maxeon 40-Year Warranty. It’s as exceptional as our quality solar technology. 

In fact, you’re 100 times more likely to return a standard solar panel than a SunPower Maxeon solar panel. And since our 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. 

Our Maxeon panel’s 40 year warranty is one more way we make life better with solar. This warranty is available worldwide.
