Photovoltaic module soiling studies, May 1978-October 1980

Description: The retention of particulate contamination on the surface of flat-plate photovoltaic devices is adversely affecting electrical performance of outdoor-exposed modules. The results of an experimental study being performed by the Jet Propulsion Laboratory's Low-Cost Solar Array Project to characterize and understand the effects of outdoor contaminants on sensitive optical surfaces of flat-plate photovoltaic modules and cover materials are described. Comparative electrical and optical performa… more

Bias-humidity testing of solar-cell modules

Description: The feasibility of implementing bias-humidity development testing to determine if field-like failure modes would result is demonstrated. Variables resulting in degradation were separated so causative variables could be identified. The studies were done on silicon solar cell modules from different manufacturers. Following each of the ten-day bias-humidity tests, the modules were examined, photographed, and tested. Limited bias-related changes were observed. (LEW)
