Canadian Solar modules pass high voltage endurance tests
Jul 23, 2012 - Solar products maker Canadian Solar Inc (NASDAQ:CSIQ) today said its modules had passed high voltage endurance tests of the Photovoltaic Institute (PI) Berlin and Berkeley, California-based PV Evolution Labs.
The resistance of the company's CS6 poly series modules to high system voltages, formally called Potential Induced Degradation (PID), was tested by both the PI Berlin and PV Evolution. The US laboratory also tested Canadian Solar's CS5 mono series.
The solar company said that there were still no test standards for the PID phenomena acknowledged across the industry and that it had developed a test method in conjunction with PV Evolution. The method used by PI Berlin had been created by PI Berlin, the TUV Rheinland, the German Association for Electrical, Electronic & Information Technologies (VDE) and the Fraunhofer Institute for Solar Energy Systems ISE in cooperation with major solar firms. Canadian Solar also said that its modules had qualified for the top rating at PI Berlin -- PID Class A.
