JA Solar Modules Pass Salt Mist Corrosion and Sulfur Dioxide Corrosion Tests Conducted by TUV NORD

Monday, February 25, 2013

JA Solar Modules Pass Salt Mist Corrosion and Sulfur Dioxide Corrosion Tests Conducted by TUV NORD03:00 EST Monday, February 25, 2013SHANGHAI, China, Feb. 25, 2013 (GLOBE NEWSWIRE) -- JA Solar Holdings Co., Ltd. (Nasdaq:JASO) ("JA Solar" or the "Company"), one of the world's largest manufacturers of high-performance solar power products, today announced that all of its PV module series have successfully passed salt mist corrosion and sulfur dioxide corrosion tests. The independent tests were conducted by TÜV NORD AG, a leading multinational provider of inspection, product testing and certification services. The test results confirm that JA Solar's products offer exceptional reliability even in severe environments. High salt concentration and humid conditions are associated with coastal regions and certain pastoral farming areas. Prolonged exposure to these conditions may corrode module components including the frame, junction box and glass, causing lower module power output. Conducted against IEC61701 standards for power output, ground continuity, wet leakage current, insulation resistance and appearance, the salt mist corrosion test revealed that JA Solar's modules are in conformance with the aforementioned standards and are able to maintain high performance even under extreme conditions. JA Solar's modules also passed a sulfur dioxide corrosion test. High sulfur dioxide concentration, common in volcanic areas and around chemical manufacturing facilities, can cause corrosion in PV modules and decrease energy output. JA Solar's modules were tested against DIN EN ISO 6988-1995 standards, involving exposure to sulfur dioxide for a period of 480 hours, and were tested for power output degradation, ground continuity, wet leakage current, insulation resistance and appearance. JA Solar's modules successfully passed the test and showed less than 5% power output degradation. "We are delighted with the strong performance of JA Solar's modules under TÜV NORD's stringent testing, and we pride ourselves on our products' ability to function reliably under the most challenging conditions," said Mr. Yong Liu, CTO of JA Solar. "Our commitment to continuous technological innovation is vital to our ability to provide our customers with high-performance, high-efficiency and high-reliability products."Forward-looking Statements This press release contains forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.
