Faster, Better, Cheaper: An Institutional View
The focus in solar system exploration has shifted to a faster, better, cheaper approach featuring focused, technically sophisticated, fast track missions.
Environmental testing of flat plate solar cell modules
Commercially available flat-plate solar cell modules have been subjected to a variety of environmental tests designed to simulate service conditions. Among the tests are those simulating heat and rain, wind-driven rains, humidity and freezing, humidity and heat, humidity with a voltage bias, salt fog, hail impact, and fungus infestation. Tests for optical surface soiling and the combined effects of temperature, humidity and UV irradiation are under development. A correlation has been demonstrated between degradation caused by the qualification tests and such observed field effects as power loss.
