Low angle solar performance
Has my one seen data on performance by specific panel or general PV type for different incidence angles of solar radiation? All I can find so far is generic info. Jim

"Test results show nearly identical relative light transmission plots for all five test modules with glass superstrate regardless of the type of PV cell technology. (This project tested monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium gallium selenide). This indicates that the reflective losses are governed almost exclusively by the air-glass interface of the PV modules.
The relative light transmission plots obtained using the IEC 61853-2 model were in good agreement with the plots obtained using the theoretical air-glass interface models and the empirical model developed by Sandia National Laboratories for the glass superstrate PV modules.
The standard states that “for the flat glass superstrate modules, the AOI test does not need to be performed, rather, the data of a flat glass air interface can be used.”The results obtained in the current study validate this statement."
