I think you can get 15W/sqft and my Volt is not very efficient I often need 16KW if I take it easy but even at 8kw you would need 533sq feet of solar panels 23ft by 23ft. So... not a great deal but with a 32KWh battery pack you could charge it with a 23x23 panel on your roof in 4 hours. That sounds like a better deal and very manageable.

The Dolphin is a very cleaver vehicle. I wish I had some land to work on an Ultravan.
