PV Module Reliability Workshop at NREL
CFV Solar Test Lab employees attended the annual PV Module Reliability Workshop sponsored by the National Renewable Energy Lab (NREL) in Colorado this week. Many of the top manufacturers, developers, and scientists from around the globe were in attendance to discuss issues related to PV module and system reliability. The CFV poster presentation “Module Deflection Profiles for MLT” authored by Larry Pratt, Nick Riedel, Greg Peacock and Michael Yamasaki won first prize in its category “General Standards”. The poster summarized an internal CFV study done to show that the force applied by its mechanical load stand that uses discrete hydraulic pistons is roughly equivalent to other methods (like sand bags or air bags) that use a continuous applied force across the module surface. The results of the study resulted in the rewriting of a portion of the new IEC standard for Mechanical Load Testing.
