sunpower e-series solar panel
High Performance, Excellent Durability

SunPower™ E-Series solar panels deliver efficient performance, long-lasting durability at a great value. SunPower solar panels generate more energy over the lifetime of your system than other panels. Compared to other technologies, SunPower converts the greatest percentage of sunlight into electricity. This means that over the lifetime of your system, you’ll generate more electricity and save more money on your electricity bills.

Not only are SunPower solar panels the most powerful and efficient on the market, they’re also the best-looking. Thanks to our exclusive SunPower™ Maxeon™ solar cell technology, SunPower panels have no grid lines and blend harmoniously into the roof of your home. Backed by the industry’s best warranty, our residential solar panels combine brains, brawn and beauty to provide the most efficient, renewable solar power.
