Under the adjusted terms of this agreement, GCL-Poly will supply JA Solar with an aggregate of approximately 10GW of polycrystalline wafers and polysilicon products for a five-year period, from January 2011 to December 2015.

JA Solar chief operating officer Jian Xie said that this multi-year supplemental supply agreement fundamentally improves JA Solar’s supply chain positioning with an expanded strategic supply of poly-crystalline solar wafers.

"It also provides a solid foundation to support JA Solar’s rapid growth and will significantly improve our cost competitiveness in the dynamic solar industry," Xie said.
