JA Solar announced today that all of its PV module series have successfully passed the salt mist corrosion test and the sulfur dioxide corrosion test conducted by TÜV Nord.
High salt concentration and humidity conditions are often found in coastal regions and certain pastoral farming areas. Prolonged exposure under these conditions may corrode the module components including the frame, junction box, and glass, causing lower module power output. Conducted against the 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 compliance with the described standard and are able to maintain a high performance even under extreme conditions.
JA Solar’s modules also passed the sulfur dioxide corrosion test. High sulfur dioxide concentration, common in surrounding areas of volcanoes and chemical manufacturing facilities, may cause corrosion to PV modules and decrease energy output. JA Solar’s modules were tested against the DIN EN ISO 6988-1995 standards, where the modules were exposed to sulfur dioxide for a period of 480 hours and tested for power output degradation, ground continuity, wet leakage current, insulation resistance and appearance. JA Solar’s modules have 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 Yong Liu, CTO of JA Solar.
