SunPower in the 1980s
1980 - 1989

By 1985, Dr. Swanson (who by then was a professor of electrical engineering at Stanford) had been awarded grants from the Electric Power Research Institute and the U.S. Department of Energy to support his solar power explorations. With the help of these funds – as well as financial support from two venture capital firms – SunPower was officially incorporated in April 1985.

1970s SunPower
1970 - 1979

Our record of solar innovation began nearly four decades ago, when our co-founder, Dr. Richard Swanson, was pondering ways to deal with the oil crisis. At that time, solar cells were being used on satellites, a concept he found intriguing. His engineering challenge was to figure out how to make the cells more cost-effective. So he began a quest that, almost 40 years later, has helped position SunPower as a leader in residential, commercial and utility-scale solar power production.
