The reality (do the math yourself) is that even with solar panels at 100% solar-conversion efficiency it isn't feasible -- for practical purposes -- to fully power a trawler only with a solar platform that is sized within the hull's boundary. It doesn't compute. Solar is best as a supplemental charging system for the boat's batteries.
