San Jose, Calif.-headquartered SunPower Corp., a designer and manufacturer of solar electric systems, has signed a 10-year silicon supply agreement with Hemlock Semiconductor Corp., a Hemlock, Mich.-based polysilicon manufacturer.
SunPower expects the silicon supplied by this agreement to support more than 2 GW of solar cell production at planned silicon utilization rates over that period. Deliveries are scheduled to begin in 2010.
‘Our new Hemlock agreement adds another long-term component to SunPower's silicon supply portfolio strategy as we expand our high-efficiency solar cell production,’ says Tom Werner, CEO of SunPower. ‘SunPower is seeking to achieve economies of scale that will contribute to our goal to reduce installed solar system costs by 50 percent between 2006 and 2012.’
