Canadian Solar says it has achieved the highest ratings possible in two standard tests for ammonia (NH3) resistance of solar modules.
The modules were tested under the IEC 62716 draft C ammonia corrosion test by TUV Rheinland, as well as the DLG standard test for solar modules in agricultural environments. The tests included power loss, visual inspection and the insulation resistance.
Approximately 20% of PV installations in Germany are located on agricultural land, Canadian Solar notes. Due to the high ammonia concentrations found in the air of animal stables, the resistance of modules is of particular relevance for maintaining PV power output in agricultural businesses.
Both TUV Rheinland and DLG procedures test solar modules for their resistance against NH3 corrosion, allowing for a maximum power loss of 5%. The solar modules made by Canadian Solar passed both tests without showing any performance degradation.
TUV Rheinland certified the modules CS6P-P and CS6P-M, CS5A-M and CS5A-P, CS6X-P and CS6X-M, CS6A-P and CS6A-M, CS5P-M and CS5P-P, CS6C-M, CS6C-P and CS5C-M-made by Canadian Solar. The DLG test included Canadian Solar's CS6P-P-module.
