So I've read all about the merits of series vs. parallel set up, but I'm wondering if anyone has practical experience on the effects of shade on my trailer set up. I am in Minnesota and will be frequenting a lot of shady spots in state park campgrounds. I'm running four 200 Watt panels, so I don't really want to deal with the added wiring requirements of 4 panels in parallel, but I'm also worried about the effect of shade if I go 4 in series. So I'm thinking of splitting the difference and doing 2S2P. Anyone have practical experience on what sort of inefficiences I'm looking at if I run all in series? I know we're only adding inefficiency when some panels are shaded and some are in sun, which maybe makes this not worth a concern of doing anything in parallel. So any practical experience or wisdom is welcome. Since I am in Minnesota I've already sort of overdesigned the amount of panels needed, accounting for not being in an ideal spot for solar.
