SunPower Corp. announced this week a silicon supply agreement totaling over $250 million. South Korean chemical company, DC Chemical, will provide polysilicon for SunPower's solar photovoltaic (PV) module manufacturing operations.
The agreement calls for SunPower to purchase approximately $250 million of polysilicon over a four-year period from DC Chemical's new facility, which is expected to manufacture 3000 metric tons of polysilicon per year.
SunPower will support construction of the facility with a series of advanced payments over the next year. DC Chemical's polysilicon supply will provide a guaranteed source of raw material to make ingots for SunPower's solar cells.
