“We see a decoupling between what modules are expected to survive based on previous industry knowledge, and what they’re actually able to survive in testing,” says Colin Sillerud. Image: CFV Labs.
Over the past five years, solar panel design has evolved, with larger modules, thinner frames and different glass types becoming more commonplace. However, a representative from an independent third-party PV test and research lab suggests that this had led to a weakening of mechanical stability in modules.
“We’ve seen a dramatic rise in the number of projects in the field, that we have been asked to work on, where they have had mechanical failures, meaning module glass breaking, at unexpected, or concerning stages in the project’s life; sometimes as early as before the plant has even been commissioned,” Colin Sillerud, vice president of engineering at Albuquerque-based test lab CFV Labs, tells PV Tech Premium.
