Canadian Solar’s modules were recently tested in the IEC 62716 draft C ammonia (NH3) corrosion test by TÜV Rheinland and also in the DLG standard test for solar modules in agricultural environments. Testing concluded that the company’s modules passed with the highest possible ratings and included power loss, visual inspection and insulation resistance.
Both TÜV Rheinland and DLG tested the solar modules for their resistance against NH3 corrosion with a maximum allowed power loss of 5%. Canadian Solar modules passed both tests without showing any performance degradation. TÜV Rheinland’s ammonia corrosion test exposed the modules to extreme conditions for a 20-day test cycle, being exposed to 6,667ppm of NH3 under 8 hours of 140° F (60° C) with 100% relative humidity and then 16 hours of drying in standard atmosphere without ammonia under 73°F (23° C) and a maximum of 75% relative humidity.
The TÜV Rheinland cycle was repeated 20 times with Canadian Solar modules showing less than 0.8% power loss. The DLG NH3 resistance test examined the modules’ performance under ammonia exposure by exposing the modules to 750ppm of ammonia clouds at 158 °F (70° C) for 1,500 hours. The test simulated a 20-year lifetime and saw Canadian Solar’s modules show less than 1.3% power loss during the test.
“We pride ourselves in our R&D and innovations, as we are able to provide customers and partners with superior PV products. The ammonia tests are the latest to underscore the suitability of our panels in real world applications in Germany and worldwide,” said Dr. Shawn Qu, chairman and CEO of Canadian Solar.
TÜV Rheinland certified modules CS6P-P, CS6P-M, CS5A-M, CS5A-P, CS6X-P, CS6X-M, CS6A-P, CS6A-M, CS5P-M, CS5P-P, CS6C-M, CS5C-M. The DLG test included the CS6P-P module.
