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

Exactly. But the numbers above are pure light reflection losses *before* applying the cosine power reduction for angle to solar production. These losses are before any light hits the photovoltaic cells (when mounted under smooth glass as is typical).
Many have probably noticed this effect looking through a window from the side with much more light, say out at night, or looking into a house on a sunny day. Looking straight it is pretty easy to see in. Looking nearly parallel down the length of the glass, you see the reflection instead.
