I'll be mounting 4-6 100W panels on the roof of my RV. The RV roof is somewhat curved, and space and shade (A/C shadow) limitations prevent long consistent arrays.
This is a 12v battery system with a 150v max input MPPT controller - so pretty much all options are on the table.
So given that the panels will likely be of varying orientation and varying inclination, would you recommend running them all in parallel? I was somewhat arbitrarily thinking of running them in 2-3 panel sets of 24-36v... but that was mostly due to wiring size simplification (2 8AWG runs from the roof). But if there was a significant benefit, I could wire them up with each panel in parallel. I would cost me another $60 in fuses.... while an extra 100W panel costs about $125.
Tradeoffs... Just curious if anyone had any opinions. Solar's tough on the interwebs... lots of conflicting opinions.
