SUS 304# Stainless Steel Temperature And Humidity Test Chamber For Lab Use

PV solar modules testing instrument temperature and humidity

test chamber for lab use

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 :

Thermal cycle test;

Humidity-freeze test;

Damp Heat;

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:

(IEC61646 , IEC61416 ,IEC61215 , UL1703 , IEC62108 , IEEE1513 ,IEC61730 etc ) .
