SunPower Background

Founded in 1985 by Richard Swanson

SunPower was founded in 1985, by Richard Swanson, who was a Stanford University professor focused on electrical engineering. Swanson studied solar power efficiency in the Stanford Electronics Laboratory with funding from research grants. After breaking a record for solar power efficiency in lab conditions, he took a sabbatical to start SunPower and commercialize the technology.

Industry Leading 25-Year Complete Warranty

Only U.S. solar company that’s been around longer than its 25-year warranty. Every component is designed to work together, so SunPower® stands behind your entire system for the 25-year confidence warranty (not just the panels). However, as only 1 in 20,000 SunPower panels fail, it's the best warranty you may never have to use it.
