Intersolar 2013: Yingli Green Energy Leads the Game in Quality and Sustainability

Outstanding Test Results for YGE 60 Cell Series and PANDA Modules

BAODING, China, June 18, 2013 -- Yingli Green Energy Holding Company Limited (NYSE: YGE) ("Yingli Green Energy" or the "Company"), a leading solar energy company and the world's largest photovoltaic ("PV") manufacturer, which markets its products under the brand "Yingli Solar", leads the game when it comes to setting the standards for quality and sustainability in the PV industry. At Intersolar Europe, the world's leading exhibition for the solar industry taking place in Munich from June 19-21 2013, the Company showcases its latest products of multi- and monocrystalline PV modules. Yingli Solar products have recently achieved outstanding test results in Germany. Abiding by its role of being at the forefront of sustainable development, Yingli Green Energy is going to present its vision of a low-emission PV industry at the trade show.

Yingli Solar products have been on the market for ten years. They win over by their high quality and module yields which has been proved by in-house lab tests as well as comprehensive field tests executed by independent testing institutes.

PHOTON Module Yield Test 2012: Outstanding Test Results for Yingli Green Energy

In the PHOTON Module Yield Test 2012 executed by PHOTON labs, Yingli Green Energy's flagship multicrystalline module (the YGE 60 Cell Series, YL240P-29b) generated an annual yield of 1,118.7 kilowatt-hours per kilowatt. According to the test result, the performance ratio of Yingli Green Energy's module reached 93.1% and exceeded that of the winner from the same test in 2011 by 2.8%. This performance ratio indicates what percentage of the incoming solar irradiance converts into electricity.

TUV Rheinland 2011 Energy Yield Test: Second Place for Yingli Green Energy

TUV Rheinland attests the high performance of Yingli Solar modules. From September 2011 to August 2012, TUV Rheinland tested fourteen modules from eleven PV manufacturers from Europe, North America and Asia. All modules were tested under high temperature and low irradiation. 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. According to the test result, the electricity output of the PANDA module was 0.6% lower than the top performer, 2.9% higher than the average level and 5.0% higher than the lowest ranking module.

The Company's multicrystalline PV module also 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.

"Customers around the world choose our modules for their performance, quality, and reliability. The current test results confirm that our products deserve their trust. One pillar of our corporate philosophy is our commitment to research and development. We integrate our research findings into our production processes which guarantees high yields and a long life-span," said Mr. Liansheng Miao, Chairman and Chief Executive Officer of Yingli Green Energy.

WWF Climate Savers Program: A New Era of Low Carbon Photovoltaic Production

Yingli Green Energy became the first Chinese company and the first PV manufacturer to join the Climate Savers program initiated by World Wide Fund for Nature (WWF) in January 2013. The WWF is one of the most recognized nature conservation organizations. Initiated by WWF in 1999, the Climate Savers program now counts 30 member companies, including Johnson & Johnson, IBM, Nike, Hewlett Packard, Xanterra Parks and Resorts, Sagawa, Sony, Tetra Pak, Lafarge, Catalyst, Novo Nordisk and Nokia Siemens Networks. The member companies set sector-leading targets for greenhouse gas ("GHG") reduction in their own emissions and work with other companies, suppliers and partners to implement innovative solutions for a clean, low carbon economy.

Yingli Green Energy aims to set an example by constantly increasing its own share of renewable energy consumption. The Company operates more than 20 MW of solar installations on its manufacturing bases to power their production facilities. By the end of 2015, Yingli Green Energy expects that at least 4% of its total energy consumption will come from renewable sources. Yingli Green Energy is the first company in China to commit to a renewable energy target. Besides setting its own emission reduction targets, the Company calls on its suppliers. Within the scope of "Green Supplier Action" suppliers are requested to adopt ambitious energy efficiency and greenhouse gas reduction commitments.

"The pledge to sustainable development is one of our core values. We are convinced that cutting carbon emissions and spurring economic growth can go hand in hand. We are also engaged in numerous sustainability projects aiming to provide affordable green energy for everyone. We all have to act in concert to leave an environment worth living for the following generations", said Mr. Liansheng Miao, Chairman and CEO of Yingli Green Energy.
