Three-Year Solar Cell Supply Agreement Begins in 2007

SunPower Corporation subsidiary PowerLight Corporation, today announced a 120 megawatt, three-year supply agreement with JingAo Solar Co., Ltd. ("JingAo"), a privately-owned solar cell manufacturer based in Hebei, China. The agreement calls for JingAo to deliver increasing volumes of silicon solar cells to PowerLight beginning in 2007. This contract is the third in a series of long-term PV cell contracts completed by PowerLight over the last year.

"We are very pleased to announce this supply agreement with JingAo," said Dan Shugar, PowerLight president. "Increasing our solar supply will allow PowerLight to expand our business faster, especially in large-scale power plant and commercial applications.

We believe that JingAo will be a highly-reliable supplier, due to strong upstream ingot supply relationships. We look forward to adding JingAo solar cells to our supply base to complement our other long-term supply partners and internally-sourced SunPower solar panels" - SunPower.
