Tests in climatic chamber provides accelerated aging of PV modules. It is thus possible to determine what will be the PV modules performance for several years of operation under normal weather conditions.
Expresion of the results of climatic test is based on the differences between results of the test that are performed before and after the climatic test:
Climatic tests are performed in a climatic chamber EWSX282-30CW with automatic regulation of temperature and relative humidity from manufacturer Espec North America.
Test is performed according to IEC 61215:2005.
PV modules are subjected to cycling between temperatures 85°C with relative humidity 85 % and -40°C. PV modules are subjected to 10 complete cycles in the closed climatic chamber in accordance with the profile on the picture bellow.The purpose is to determine the ability of the module withstand against humidity penetration.
