  Photovoltaic Modules Test Equipment List

1.Damp Heat Test (Double 85 Test )

Test Purposes: To determine the ability of the module to withstand the effects of long-term penetration of humidity.

Test Requirement:Put the modules into the chamber according national standard and IEC61215\UL1703,Test Temperature 85 ± 2 ,Test Humidity 85% ± 5%,Test Time 1000h or 3000H.

Equipment : High Temperature &High Humidity Test Chamber

2.Humidity-Freeze Test  

Test Purposes:  The purpose of this test is to determine the ability of the module to withstand the effects of high temperature and humidity followed by sub-zero temperatures. This is not a thermal shock test.

Test Requirement: Method:Put the modules into the chamber accoring to national standard andIEC61215\UL1703,Test Temperature 85 ± 2 ,Test Humidity 85% ± 5%,Test time 20h ,then test under -40 for0.5h ,10times cycling ;which the temperature rising and falling speed requires:100or 200/H .

Equipment :  High-low Temperature Humidity Test Chamber

3.Thermal Cycling Test

Test Purposes: To determine the ability of the module to withstand thermal mismatch, fatigue and other stresses caused by repeated changes of temperature.  

 Method:Put the specimen into the chamber according to national standard and IEC61215\UL1703,Test Temperature-40 ,Test time 10M ,then under 85 ± 2 for 10M ,continuously 200 times cycle,in which temperature rise/fall speed requires 100/H .

Equipment : High-Low Temperature Cycling Chamber

4.UV Preconditioning Test

Test Purposes:  To precondition the module with ultra-violet (UV) radiation before the thermal cycle/ humidity freeze tests to identify those materials and adhesive bonds that are susceptible to UV degradation  

Method: Put the specimens into the UV aging chamber according national standard and IEC61215\UL1703,using 340nm wavelength UV for component and raw materialradiation.  

Equipment :  UV Aging Test Chamber

5. Corrosion Test

Test Purposes:  To determine the module ability to withstand corrosion

Method: Put the specimens in the salt spray chamber according to national standard and IEC61215\UL1703:Temeprature setting : saturated air barrel: 47℃(+/-1;

Testing room:35℃(+/-1; Angle 35°.

Equipment :  Salt Spray Test Chamber

6. Hot Spot Endurance Test

Test Purposes: To determine the ability of the module to withstand hot-spot heating effects, for example solder melting or deterioration of the encapsulation

Method: Put the specimen into the xenon aging test chamber accoring to national standard and IEC61215\UL1703:Temperature +25~+85;Wave Range295-780nm;Humidity 45%~98% ; Rain Pressure 80~120KPA ; Testing Time 300H .

Equipment : Xenon Light Aging Test Chamber
