Failure rates for TC200 can be as high as 30-40%. If in combination with Damp Heat, in some
laboratories both can account for more than 70% of the total failures for c-Si modules.
TC200 failure rate is lower for thin-film, but still worth the attention of the manufacturers.
Humidity-freeze: is an environmental test.
The purpose is to determine the module’s ability to withstand the effects of high temperatures combined
with humidity, followed by extremely low temperatures.
The module is subjected to 10 complete cycles as per harmonized profile below (IEC 61646).
