First, here's a quick recap of my solar-electric VW bus conversion.

With the advent of thin, semi-flexible solar panels weighing in at just 6 pounds per 150 watts, the weight limitation of solar panels on vehicles has been lifted. For the weight of a well-fed man, a solar-powered vehicle enthusiast can include a level two charger on board. That’s over 6,000 watts of charging power. On my electric VW bus, that’s a full 100 miles of range in 5 hours of direct solar exposure. (Tracking the sun at all would give the opportunity to grab significantly more miles per day.)

That’s wonderful, but there is a catch: surface area. 5 kilowatts of solar panels would require five 1,000-watt arrays, one on each side of the van, plus the center. Obviously, now with a 15-foot width and some extremely floppy panels, we would have a problem. But what if we fold the panels in? We can then stop, unfold, and charge while we have lunch or enjoy a river swim.

Better yet, with all this unfolded surface area, we have a large shade roof. If I set it up as it is in my mind: a Solar-Electric Transforming Tiny House! It’s an off-grid mobile tiny home with all the electricity you need to heat, cool, light and then drive! In other words, we have a photovoltaic electric-vehicle RV, or "PV EV RV"!
