Alternative MAST Testing Protocols

Real world testing for today’s PV modules

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.

Damp Heat and Thermal Cycling

Combines two important stress factors in a shorter test not requiring full size, expensive UV equipment.

 

 

 

 

 

 

DH/TC exposure to assess backsheet cracking in full size modules.

UVA and Water Simulation

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