History of SunPower Corporation

SunPower Corporation was founded in 1985 by Dr. Richard Swanson, a solar pioneer and the inventor of the Point Contact Solar Cell. Initially, the company focused on developing high-efficiency solar cells for space applications, but later expanded to provide solar solutions for residential, commercial, and utility-scale projects.

In 1999, SunPower was acquired by Cypress Semiconductor Corporation, which allowed the company to expand its product offerings and accelerate its growth. The company went public in 2005, and in 2011, Total S.A., a French multinational energy company, acquired a controlling stake in SunPower Corporation.

Today, SunPower Corporation has a global presence, with operations in North and South America, Europe, Africa, and Asia. The company has received numerous awards for its innovative and sustainable solar solutions, and its solar panels have been used in some of the world’s largest solar power plants.

When shopping for solar power systems from SunPower, you can expect to pay an average of $2.70 per watt for a home system. This cost may vary depending on how much power you need and other factors such as local installation costs and any incentives or rebates offered by your state or utility company. For example, in California the average price is typically lower due to the availability of some Solar Tax Incentives (STI) credits.

The cost also includes hardware like panels, inverters, mounting equipment and other necessary components; however labor charges are not included in this estimate.
