Canadian Solar has announced it is one of the first PV providers to have passed two high voltage tests.
The company says that the Photovoltaic Institute (PI), Berlin, has tested its CS6-poly-series module and the PV Evolution Labs assessed both its CS5-mono-series and CS6-poly-series.
Tests measured the sensitivity of the module output parameters when exposed to high system voltages.
According to Canadian Solar, in compliance with the standard set by the PI Berlin, TÜV Rhineland and the VDE (Association for Electrical, Electronic & Information Technologies), the company’s modules were exposed to a negative socket voltage of 1,000 volt. During the test the grounded module front is covered in either aluminium foil or a layer of water. The-before-and-after performance rate was measured with a flasher under standard test conditions. The Canadian Solar module performance rate was found to be still higher than 98 percent following the endurance test. Canadian Solar requested PI Berlin to double the standard stress time for the ultimate quality assurance. All Canadian Solar modules demonstrated very little further degradation during the additional aging period and the final results were still qualified for the top rating, PID Class A, at PI Berlin.
“Such tests provide an important measure of orientation to our customers. The results demonstrate that they can count on the high quality of our products,” said Dr. Shawn Qu, chairman and ceo of Canadian Solar.
“We believe that we have some of the most advanced and highest quality products available in the market today. One of the reasons for this is that we have never shied away from investing into this area. This has now paid off.”
