SunPower photovoltaic panels (or modules) are universally recognized as the highest quality product on the solar market and have been for many years.
There are over 100,000 residential SunPower solar systems installed worldwide. This is due to SunPower’s technology, quality product, and system guarantees.
SunPower solar panels use the highest grade monocrystalline silicon and Maxeon™ cell technology, resulting in the only solar cells built on a solid copper foundation. SunPower cells are virtually impervious to corroding and cracking, which commonly causes degradation in conventional panels.
SunPower was the first manufacturer to offer a 25 year performance guarantee and continues to lead the industry in innovation and relentless quality control.
