Performance, Reliability, Value
SunPower® Performance Series panels are designed to deliver consistent performance and excellent value to businesses, government, and power plant customers. The unique panel design produces more power than conventional commercial panels when there is shade, debris, and dirt, meaning more energy over the lifetime of the system.3 SunPower builds Performance Series panels with its proven module materials, including a proprietary encapsulant that prevents PID and protects the solar cells from degradation caused by moisture.
- More energy: Performance Series panels deliver more energy than conventional panels due to higher performance in row-to-row shading. The unique parallel circuitry limits shading loss to the shaded area, whereas power loss on conventional panels greatly exceeds the shaded area.1
- More reliability: Robust shingled design replaces soldered copper ribbons with flexible connections, providing superior durability under thermal expansion and contraction. Smaller solar cells carry 1/6 of the current so they stay 50% cooler when partly shaded, enabling longer panel life.2
- More power: The Performance Series design minimizes white space between solar cells, eliminates reflective metal lines on the cells, and lowers electrical resistance between cells, increasing efficiency compared to Conventional Commercial Panels.3
- More peace of mind: Tested to SunPower’s rigorous quality standards and backed by the industry’s best 25-year Combined Power and Product Warranty.4
