If you scaled down and accepted kevel one charging you could use 550 5 inch cells. 2000 watts. Have a 8 x 12 foot tear drop trailer. It might push you 15 mph on level ground or charge you in 21 hours. Many variations for shape, power and speed. I would have eyelets on each corner to tie it down in high winds. The whole DIY build would be plywood on a light weight trailer.
When you're aiming for efficiency, I think a trailer is a liability. It would be better to shape the vehicle itself to have as much roof area as possible, and use as little energy as possible. Essentially what you see in cars like Stella, or the solar raycers.
The vehicle can also be specialized for your particular situation. How far do you drive in a day? Maybe you can size the PV panels and batteries so it can work for you with little or no grid charging. Maybe the PV panels can unfold when parked, to significantly increase their area.
