Thermal Cycling Chamber for PV Module

1.PV Module Thermal Cycling Test Purposes:
To determine the ability of the module to withstand thermal mismatch, fatigue and other stresses caused by

repeated changes of temperature.

2. PV Module Thermal Cycling Test Test Requirement:
Method:Put the specimen into the chamber according to national standard and IEC61215UL1703,Test Temperature-40 °C,Test time 10M ,then under 85 ± 2 °Cfor 10M ,continuously 200 times cycle,in which temperature rise/fall speed requires 100°C/H .
