I can't say anything to the power efficiency of solar cells, but I can see how they could be useful for when you're not flying. "Free" energy for when you're ready to fly if you don't fly the plan daily, but instead just fly on the weekends or such. In the middle of nowhere without fuel or electric hookup? Wait a few days and at leas the plane will have energy to fly out of there. I'm not saying that will be the case, but an interesting aspect of solar panels on wings.

You'd be much better off to simply have a few panels on a rack that you put out next to the plane. Being forced to haul around the extra weight of the panels on the top of the wings would be counterproductive, and if you really wanted the panels with you one day, you could pack them up and take them with you.
