That sure is funny-looking.
Lat + 24 degrees? Just the knee jerk response.
I did not put a lot of faith in tracking before.
Now, after many years of watching the sky, I do.
Today is a good example. Bright clear blue sky. Until about an hour or 3 after sun rise. Cloudy all day. Now, with 2 hours until sun set, bright blue sky.
Today would make most PV power whem the power should be dropping off.
The vast majority of todays solar power, here, would have come from South of an East/West line.
I need to test a thing or 2, so I have been watching. Even if I can't do it when it it is a good time.
I am in the snow belt. Here, winter is much worse. It happens very often, sometimes for weeks on end. Can go many days without a shadow, but the night stars are bright. I have much less faith in the carts and calculations than a did a few years ago (for here), and I believe tracking could make some major improvements over the calculated solar insolation for PVs.
