Tilting Solar Panel
I did a little experiment. I have a new poly 100 watt panel. Before installing I tilted the panel to face directly into the sun. 19.6 volts. I tilted it the same angle, but away from the s...

I also did some measurements. This was in May at 49N latitude, using a 130w panel where I was able to take all-day AH hauls over three days with the same perfect sun conditions.
Tilted up and also aimed during the day- 90AH
Tilted up fixed aim South- 70AH
Flat- 56AH
A second panel lying flat would be 56 x 2 = 112AH, more than the single panel tilted and aimed getting 90AH.
It is situational what to do about that. When we went there for a few years seasonal off-grid all summer with the 5er, I chose single 255w panel ground- mounted in a tilted, twirler contraption. With the MH, and not seasonal anymore, but still off-grid a lot, I chose more panels flat on the roof.
