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

Don't forget that low angle sun is when it is in atmospherics up to say 15 degrees altitude, so even if your panel is great at low angle stuff, it doesn't matter because the light is going through haze etc.
That is why they usually define the solar day as from mid-morning to mid afternoon.
You can do a bit more if you can squeeze out every little bit, but it doesn't come to many AHs out of your whole day.
Another example is with my "tracking" contraptions. It isn't worth the bother of tracking all day. Three moves a day gets almost as many AH due to the panels being able to get fairly good input off angle between moves.
