Beyond-certification testing is one of the industry’s most valuable tools for mitigating project and supply chain risk. Environmental stresses vary according to location. Product performance differs based on exposure. With the right data, these differences are not random but rather statistically predictable.

Developed by and for solar industry stakeholders, the first-ever commercial reliability and durability test standard for PV modules has been “separating the wheat from the chaff” since 2011. The Thresher Test was the product of a bottom-up collaborative effort involving an ad hoc team of experts led, in part, by RETC.
