The SunPower Difference
Since 1985, it has been the SunPower mission to provide the most reliable and efficient solar systems available. With more than seven million panels powering the globe, SunPower has proven the durability and reliability of our panels. We credit our success to the unique design of our patented SunPowerTM MaxeonTM solar cell technology. By offering the industry’s first combined power and product warranty, we are underlining our continuing commitment to deliver the best solar experience in the market.

The Design Difference
SunPower Maxeon solar cell technology
The design of SunPower Maxeon solar cells is unique because each cell is built on a solid copper foundation — providing the strength and durability to survive conditions that panels are subjected to year after year.
