SHANGHAI, April 21, 2011 /PRNewswire/ -- Hanwha SolarOne Co., Ltd. ("Hanwha SolarOne" or the "Company") (NASDAQ: HSOL), a vertically integrated manufacturer of silicon ingots, wafers and photovoltaic ("PV") cells and modules in China, today announced quality certifications for its new crystalline solar modules in the British, North American, and German markets.  The new certifications come from three independent quality certification bodies including U.S.-based Underwriters Laboratories Inc. ("UL"), UK-based Microgeneration Certification Scheme ("MCS"), and Germany's Technischer Uberwachungs-Verein [Technical Inspection Association] ("TUV Rheinland").

To date, Hanhwa SolarOne has maintained a strong portfolio of UL-certified crystalline modules.  Long recognized as a guarantee of high performance, safety, environmental friendliness and quality, certification from UL is essential for products sold in the U.S. market.  The Company's most recent certifications include its X-tra serial and Black Diamond modules, as well as some from its standard line.

The Company has also validated a significant number of modules through TUV Rheinland, recognized across Europe as the highest guarantee of product safety and performance.  Similarly, for the UK market, products bearing the MCS mark are likely to be seen as the preferred option in the market place.  MCS is also linked to financial incentives which include feed in tariffs.

Dr. Peter Xie, President and Chief Executive Officer of Hanwha SolarOne, commented, "I am very pleased to announce the latest international certification achievements of our newest crystalline modules. As we grow into a global company, we continue to make every effort to ensure the market-leading safety, reliability and performance that our brand has become known for, is extended to all of our customers.  The UL certification extends even more of our high-quality products to the North American market, while the MCS and TUV Rheinland labels will enhance our offerings in the United Kingdom and EU.  The certifications are a great accomplishment, and are a strong signal of our company's commitment to expanding in these markets."
