I have a 2S 2P setup on my camper with 4x100w panels and a 110Ah LiFePo4 battery. I use the camper a lot in the winter when yield from the solar is low, especially since the panel are flat on the roof. I am thinking about making adjustable angle brackets for the panels, but i think I can only use them on two without casting a shadow on 3&4. Is this worth it, or will the two horizontal panels pull down the extra available from the two at an angle? If there is a benefit, how would it be best to connect them? i.e. 1 pair in series or one from each parallel set.
