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)
