DH/TC exposure to assess backsheet cracking in full size modules.
ASTM G155 or SAE J1960 protocols in a weatherometer for backsheet coupon or minimodule
Repeated sequential stress mimics field degradation not detected by single tests and current industry standards.
In addition to the preferred test above, we have also developed two additional sequential tests that share many features of the preferred test but provide test equipment flexibility.
Additional Sequential Tests Provide Test Equipment Flexibility
Damp Heat and Thermal Cycling combines two important stress factors in a shorter test not requiring full size, expensive UV equipment.

UVA and Water Simulation
Combines UV and rainfall simulation, common weathering test conditions using commercially available weatherometer.
