Yingli Green Energy Holding Company Limited (NYSE: YGE) ("Yingli Green Energy" or the "Company"), a solar energy company and one of the world's largest vertically integrated photovoltaic ("PV") manufacturers, which markets its products under the brand "Yingli Solar", announced that the Company's multicrystalline PV module has excelled in the "2010 Energy Yield Test" by TUV Rheinland, ranking the second best amongst thirteen PV modules from eleven participating PV manufacturers from Europe, North America and Asia.

Lasting from May 1, 2010 to April 30, 2011, the year-long test measured actual energy yield of PV modules manufactured by all participants under real solar conditions as contrast to sunlight simulators. By calculating the average energy yield of all PV modules, Yingli Green Energy's multicrystalline PV module generated an energy yield of 1.4% higher than the average level, which is 3.1% higher than the bottom performer, and merely 0.3% less than the top performer. To put this into context, for a 30 kWp commercial project built in Germany, Yingli Green Energy's multicrystalline PV modules would generate approximately 1,000 kWh more electricity per year than modules of the bottom performer.

"High-precision test equipment for continuous maximum-power-point tracking and additional I-V-curve measurement was set up at our test site in Cologne. For the period of one year, the energy outputs of thirteen different PV modules from eleven participating companies were measured. The data was then normalized to 1 Wp of the TUV Rheinland measured STC power and compared with one another," said Mr. Christian Bauerdick, project manager of the "2010 Energy Yield Test" at TUV Rheinland. "The results can give an idea about the performance under real conditions for moderate climates like in Cologne, Germany."

"We participated in this test for the first time and won a respectable place amongst peers," Dr. Dengyuan Song, Chief Technology Officer of Yingli Green Energy, commented. "We are very pleased with our test results, which we believe reflects the superior quality of our products."

Mr. Liansheng Miao, Chairman and Chief Executive Officer of Yingli Green Energy also commented, "The results demonstrated our continued focus on technology improvements and process efficiencies to yield superior operating performance and stability, which in turn brings higher investment returns to our end customers."

Note: The relative measurement of "2010 Energy Yield Test" by TUV Rheinland leads to a measurement uncertainty of +1% and -1.5%, which has to be considered when comparing the results of the participating products.
