Creating the world's most powerful solar doesn't happen by accident--it's the direct result of our passion and the unique way we approach every part of the process. 

We hold the world record in solar efficiency, which means our products are up to 50% more efficient than the competition and generate about two times the power with the same roof space.

As a result, SunPower has the largest install base in North America -- including homes, commercial sites and utilities -- and we're proud to say that over the last two years, we've installed more systems in California homes than any other provider.

When you purchase a SunPower® solar system, you're getting the same technology used in our large commercial and utility-scale systems. The same technology that still performs on cloudy or rainy days and for longer hours every day.

But our technology isn't the only reason for our success. We also offer an industry first--a 25-year warranty that can guarantee exceptional system performance. Download the PDF now > 

Best Design

To create a truly great product, we believe that performance and aesthetics must go hand in hand. That's why our panels are the best looking on the market. They're smooth, dark and have no metal grid lines, so they blend harmoniously into your roof--adding value to your home.
