Baoding, China: Yingli Green Energy Starts Up Ingot Production

Yingli Green Energy has started initial and small-scale production of polysilicon ingots, wafers, PV cells and PV modules from its latest 200 MW expansion project in late June 2008. Equipment is being gradually delivered on time and in-line with the installation schedule.

The Company expects to complete installation of the 200MW of expanded capacity in the fourth quarter of 2008 and the full production volume will come online in late 2008.

Once completed, the Company’s total production capacity of polysilicon ingots and wafers, PV cells and PV modules will be 400 MW.

“Given our accumulated experience over the past few years in expanding capacity, we believe that we will complete this project on time in the fourth quarter of this year,” commented Mr. Liansheng Miao, Chairman and CEO of Yingli Green Energy. “The expansion should further increase our visibility and help us meet our shipment guidance for 2008 and beyond. In addition, these new production lines feature the latest equipment, including GT Solar’s DSS 450 furnaces which have the capacity to produce 400kg ingots, and greater automation across the whole value chain. We believe this will help us better control both our operations and overall product quality as we continue our fast development in this exciting market.”
