Humidity Freeze Test Chamber For Solar Panels To determine the ability of the module to withstand the effects of high temperature and humidity followed by sub-zero temperatures. After the fabrication of a high power photovoltaic (PV) module, the most critical aspect is the duration for which the module can produce useful power. Reliability and lifetime of photo-voltaic (PV) modules are key factors to system performance and warranty and thus are extremely important as far as PV business is concerned. Outdoor field testing is an accurate method in estimating module lifetime. However, since PV modules commonly come 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. Damp/heat ( IEC 61215 MQT 13) thermal cycling ( IEC 61215 MQT 11) humidity Freeze test( IEC 61215 MQT 12) Brief Introduction for PV Modules test standards: The designed usage time for solar cell module is about 20~30years , and the reliability test is the simulation of the earth's surface photovoltaic modules (crystalline silicon and amorphous silicon thin film, concentrating) design verification, can let the module long-term operating more than 20 years in a general climate , specification requires that solar cells module do test below : To confirm the solar cell can withstand high temperature and high humidity level with the minus temperature influence
