Here's something that caught my eye- flexible roof panels. Each one is 15 inches wide and 16 feet long. They have an adhesive back, intended for mounting on hard surfaces like a trailer roof. Each roll produces 124 watts, so eight of these will make about as much wattage as a small portable generator. These flexible panels are not as efficient as glass panels, but they are cheaper. Here's a link to a vendor's description on E-Bay:

These are 24V.................
