I have played around with 90w of moveable solar panels and got good efficiency but always worried about them sprouting legs. This kept my enclosed trailer batteries topped off if the the trailer was disconnected from the camper which just powered the interior lights and water transfer pump.
The new camper will have 480w of fixed solar. I expect about half that output due to where I live and camp. I'm more of an electric consumer than Frank, so I expect to to have top off more often with the generator even if I am connected to a large battery array.
