If you’re doing 4 panels on the roof, probably be best to go S/P. Making 2 pairs in serial, and wiring the series arrays in parallel. This limits the voltage of the array to the voltage of a single series pair. And the amperage will be the amperage sum of two panels. If you buy CIGS with two sided tape, they cannot be removed. CIGS are also available with grommets instead of tape. If you want to be able to remove the CIGS, you’ll need to use the RV with Tito method. But FYI, when I sold my Micro Minnie, I got back every penny of what I spent on the CIGS. Buyer knew what they were, and wanted them. Mounting to corrugated plastic is the way to go, I think. I’m looking to place an order for a pop-up truck camper very soon. My plan is to use RV with Tito method to mount 400w of fiberglass flex panels on the roof, and have a 200w Ecoflow bifacial portable. Both sets of panels connected to my Ecoflow powerstation, so no Victron needed.
