Smaller Charging Setup

One weekend morning, I saw a short mention of some 'roll-up' solar panels that were being tested for charging EV's that were on camping trips. I believe this was being done somewhere in Australia. I haven't seen anything else about it since then.

Now I personally don't drive my car a lot and have a level 2 setup in my garage, which is more than adequate for my needs. I was wondering if ANYBODY out there makes any kind of unit that would have only one or two solar panels and a smaller battery with the proper electronics to use just for charging your car? That way you could be completely independent of the grid. I live in an area where we have a lot of sunshine.

I have seen some setups similar to this idea, but they only provide 12 volts. Maybe there are others that do have an 120 volt output, but I just haven't seen them. I am NOT looking to put the whole solar panel thing on most of my roof, for my own personal reasons. Has anybody here seen what I am talking about?
 
“One or two solar panels”, even full-sized ~ 3 foot x 5 foot roof sized panels, are going to generate about 300-800 watts in ideal conditions. That’s about 1-2 miles per hour, probably less after the DC-AC-DC conversion that would be required to feed it to the car. A charging Tesla consumes about 250-300 watts while charging just to power the computers and charging circuitry, before any juice at all goes into the battery.

Then as you point out you’d need a somewhat substantial inverter or microinverters to get to 120 or 240v AC, and then some coupled battery storage.

This just isn’t an economical prospect. The cost of such a system in relation to the benefit would make for an extremely small potential market.
