As a Sunpower authorized dealer, we are proud of the products that we sell. These panels are designed to be the most efficient on the market, with a whopping 20% efficiency, virtually untouched by the next leading panel with 15% efficiency. Not only are these panels efficient, but they are durable. Exceeding the forces of weather, snow loads, and even an elephant!
