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 with twenty five years of warranty, testing modules in field for that long period is not feasible. Thus, due to time constraints, many accelerating aging tests have been derived over the years for testing reliability of PV modules. The accelerated test protocols established by organizations like IEC and UL have been adopted worldwide as official tests to evaluate module quality and reliability standards.

Description

Humdity freeze test chamber IEC61215

Humidity-freeze test

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.

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, as well as for repeated change caused by the temperature and thermal fatigue failure, in addition to determine solar cells resistant to moisture long-term penetration ability of the test equipment design and ability to meet the relevant standards below:
