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

I find that hard to believe. Do you have a source for that?
Panel efficiency is around 14%. This test reduced reflection by 75% while increasing efficiency by only 3%. In the overall picture, reflection is a minor issue.

Well in reading solar studies and standards, it seems that as the sun angle moves away from perpendicular, the dominant loss of efficiency in typical solar cells is reflection from the top glass surface rather than the technology used.
