Vern,
That sounds like a project I would like to do. I have thought of mounting 8
SolarWorld 345 watt panels, I do not want to make this MH look like a
camper, Maybe I do not need that much energy. Trying to make the panels
lids for a storage unit on top. I would like to see more details about your
installation.
