The month-long Expo is designed to promote technology innovation and new business strategies, including the Company's recent improvements to multicrystalline silicon ingot casting. The Expo comprises nine display areas which showcase each of Yingli Green Energy's internal departments' efforts to improve their manufacturing processes and enterprise-level operations, while reducing overall costs. In addition to presentations from Yingli Green Energy's internal teams, leading suppliers of solar panel equipment and materials, including Rena GmbH and DuPont Trading (Shanghai) Co., LTD, will exhibit at the Expo.

Through research and development and aggressive product testing, Yingli's technical team is proud to announce significant upgrades to its multicrystalline silicon ingot production. By upgrading the casting furnaces, the Company has increased the silicon ingot's quality, the capacity per furnace, and the overall manufacturing line's energy efficiency. As a result, the yield rate of each casting furnace has grown by more than 1.5 percent, the capacity expanded by more than 47 percent, and the per-unit energy consumption decreased by approximately 13 percent. These results have been verified by the National Center of Analysis and Testing for Non-ferrous Metals & Electronic Materials.

"We're pleased to showcase our efforts to improve technology and reduce costs across each step of the solar PV chain, and we are particularly delighted to share these successes with key partners such as DuPont and Rena," Dr. Dengyuan Song, Chief Technology Officer of Yingli Green Energy, commented. "We're also proud of our dramatic increase in ingot quality, which will help Yingli meet growing demand for high-performing solar panels.
