Our SunPower installations come with a 25 year warranty: the panels are guaranteed to last that long. We consider the lifespan of an installation to be 30 years, but many would agree 40 years is realistic; we’ve seen panels in the field that were installed in the eighties, and they are still producing well. We are happy to be working with SunPower, a solar manufacturer with 30 years of experience upon which their warranties are based.
