SunPower

Founded in Silicon Valley, California way back in 1985, SunPower is one of the most experienced and long-established solar technology companies in the world. On top of holding the record for most efficient solar modules, they hold over 200 patents for solar technology, firmly establishing their position as a world leader in residential, commercial and even utility-scale solar power production.

SunPower has great faith in their solar panels, and back them with a 25-year product and power warranty (40 years in the case of the Maxeon line). If something ever does go wrong, they are happy to assist in the repair or replacement of faulty panels in the rare case of non-performance. This should rarely come up though, as SunPower panels are designed to be almost entirely maintenance-free throughout their lifetime and should be able to function just fine up on your roof for far longer than most other panels.

At Solargain, we offer the SunPower P3, the SunPower Maxeon 3 and the SunPower Maxeon 5.
