This is a work in progress. The roof of the trailer has a center stiffener that limits the width available to install a
solar panel. A 21” just won’t fit. What does fit are the inexpensive Harbor Freight
solar panels. I know that they are suboptimal compared to the newer panels, but they fit.
I bought the 45 watt set when our power was out at home for several weeks after a hurricane. They work good enough to charge the
battery. I’m thinking of upgrading to the 100 watt system (same panel form factor) if we keep the trailer (lusting for a slightly larger one with a shower and toilet).
My mounting system was quick and dirty. It involves 12 holes in the roof. We were about to leave on an extended trip time was limited. I plan to redo the mount, and glass over the holes.
