Customized 2000L Solar Test Chamber for PV Module Dynamic Testing

1. Application:

Solar test chamber is mainly used for reliability test of solar cells in the specification to be verified in wet, frozen, temperature cycle, humidity test etc can be monitored during the experiment the continuity of the internal circuit of solar cells in order to determine whether the fault or failure, by the system solar battery failure can be determined. 

2. Features:

Data and Monitoring software

Module surface temp, test Chamber inside temp record and display

Module voltage & current record and display

With real time display curve and of the measured data and can be stored by USB connection

3. Test Model or test project

1). Damp Heat Test:

Test Condition:   95 ±2 ºC temperature range , and 95% ±5% R.H. humidity range

Test Duration: last for 1000H,

Test Purpose: To see the reliability of the module to withstand the effects of long-term penetration of heat and humidity.

2). Humidity-freeze test 

Test Purpose: to see the ability of the module to withstand the effects of high temperature and humidity followed by sub-zero temperatures.

Test points and requirements:

-40ºC lowest temperature and 85ºC highest temperature

Max temperature rising speed rate:200ºC/Hour=3.33/min

Max temperature falling speed rate:200ºC/Hour=3.33/min

24 hours per cycle, testing for 10 cycles, 240 hours (10 days)
