Yingli Green Energy Holding Company Limited (NYSE: YGE) (“Yingli Green Energy” or the “Company”), a leading solar energy company and one of the world’s largest vertically integrated photovoltaic manufacturers, which markets its products under the brand “Yingli Solar,” today announced that its PANDA module achieved great performance in the “TUV Rheinland 2011 Energy Yield Test”, ranking the second best among all fourteen modules from eleven PV manufacturers in Europe, North Americaand Asia.

All modules were tested under high temperature and low irradiation from September 1, 2011 to August 31, 2012. By comparing the average energy output per watt of all the modules, Yingli Green Energy’s PANDA module emerged as the second best, which proved its stable performance under severe conditions.
