Thermal Cycle Test: Thermal cycle test is performed according to IEC 61215:2005 standard to test ability of PV module to withstand effects of temperature stress. This test is performed between temperature 85°C and -40°C with fast changing rate. Number of cycles is run 50 or 200 times.
Humidity Freeze Test: Humidity freeze test is performed to determine ability of PV modules withstand against high temperature and humidity conditions followed by sub-zero temperature. In this this 10 cycles are run between 85°C with 85% relative humidity and negative temperature -40°C.
Damp Heat Test: Damp heat test is performed to test effects of long exposure of humidity penetration and high temperature. In this test is performed by applying 85°C ±2°C temperature with relative humidity of 85% for uninterrupted cycle of 1000 hours.
