my MH has a solar charging system, however, my solar panel was stolen one year while I had it parked at the Atlanta Race track. But I did oder one from Grand View Trailer Sales, but I just can't remember the wattage, maybe a 100 watts.
Tarter, if you get this figured out, please let me know. I would like to know this answer as well. Although, I'm looking for probably more than moderate use.
