SunPower Corporation is a leading provider of solar energy solutions, headquartered in San Jose, California. Founded in 1985 by Richard Swanson, the company initially focused on developing and manufacturing photovoltaic solar panels. Over the years, SunPower has expanded its offerings to include battery energy storage products and has served residential, commercial, and industrial customers globally. The company was acquired by Cypress Semiconductor in 2002 and went public in 2005. In 2011, TotalEnergies acquired a majority interest in SunPower but later reduced its stake. SunPower spun off its manufacturing division into Maxeon Solar Technologies in 2019 and has since focused on services, installation, and other products. The company has continued to innovate, investing in technologies like solar micro-inverters and virtual power plant services.
