Thanks, but I have studied this and have already made the decision that I will be wiring in parallel, and I will use substantial gauge wire from the roof combiner box to the solar controller. Parallel wiring because we camp in Forest Service campgrounds and state park campgrounds, and very often during the day, parts of the roof will be shaded, and parts will not. By wiring in parallel, if one or more solar panels has it's output cut drastically by shading, and other solar panels are still in full sun, I will still get a decent amount of amps.
You are still better off running in series. If your panels have bypass diodes(most do) the effect of shading only affects the panel that is shaded.
I think the best bet is to get “enough controller” and a spacious enough combiner box to be able to wire it either way to see what really works best. At some point that’s what my plan is.
