SunPower Announces High Power, Higher Efficiency Solar Panel

October 16, 2006 by Jeff Shepard

SunPower Corp. announced that it will be demonstrating its newest solar panel, offering significantly higher power output and conversion efficiency than its current products. The new SPR-315 solar panel utilizes the company's newly developed 22%-efficient Gen 2 solar cells and carries a rated power output of 315W.

"SunPower continues to lead the solar industry with its innovative technology and smart design," said Peter Aschenbrenner, Vice President of Marketing and Sales. "Our new SPR-315 solar panel breaks the 300W power barrier while offering even higher efficiency than SunPower's previous industry-leading products."

The new design incorporates 96 of SunPower's Gen 2 solar cells that offer improved panel efficiency through a combination of enhanced cell architecture and improved packing density. Compared with conventional solar panels, the new SPR-315 allows customers to generate up to 50% more power per square foot of roof area with half as many panels.

Aschenbrenner added, "The new SPR-315 solar panel enables our customers to generate more power with fewer panels - maximizing energy production while reducing installation cost. A typical 4kW (ac rating) solar system requires 30 conventional 160W panels and covers 410 square feet of roof space. Our new SPR 315 panels produce an equivalent amount of power using only 15 solar panels on 265 square feet."

SunPower's solar panels have no moving parts, creating pollution-free electricity with no noise and low maintenance. In addition, due to SunPower's all back contact solar cell design, its high-tech, high-performance solar panels perform better than most other solar panels during cloudy or hot weather.

The new SPR-315 solar panel is planned for commercial availability in the Spring of 2007.
