Greentech Lead America: Canadian Solar, a provider of
ingot, wafer, solar cell, solar module and other solar applications, announced
its CS6-poly-series and CS5-mono-series modules have passed two high voltage
endurance tests. The Photovoltaic Institute (PI), Berlin tested the
CS6-poly-series and the PV Evolution Labs assessed the CS5-mono-series and the
CS6-poly-series.
The tests measured the sensitivity of the module output
parameters when exposed to high system voltages – formally known as Potential
Induced Degradation (PID).
During the test conducted
by PI Berlin, Canadian Solar modules were exposed to a negative socket voltage
of 1,000 volt. The-before-and-after performance rate was measured with a
flasher under standard test conditions (STC). The Canadian Solar module
performance rate was found to be still higher than 98 percent following the
endurance test.
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.
The PID test method applied by PI Berlin was developed by
the TUV Rhineland, the PI Berlin, the VDE, and the Fraunhofer Institute for
Solar Energy Systems ISE in conjunction with leading solar companies.
“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. 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,” said Shawn Qu, chairman and CEO of Canadian
Solar.
The Potential Induced Degradation phenomenon in conventional
crystalline cell technologies is recently gaining industry attention. Canadian
Solar developed a test method together with the PV Evolution for this purpose,
actively promoting the development of PID standards at the International
Electrotechnical Commission (IEC).

Solar supplies solar modules for 8 MW PV installation in Germany
Recently, Canadian Solar delivered solar modules for an 8
MW PV installation built in the German city of Dreieich-Buchschlag. The PV
system is expected to generate enough clean power for up to 2,000 homes in
Dreieich. When completed, the system will be the biggest solar park in the
Federal State of Hesse.
