Would some additional solar panels on such lightweight EVs roof and bodywork be worth the added expense?

Yes, but you need to oversize your array by a factor of 3!
For every 3 watts in you would get 1 watt into your EV!
You would definitely need an efficient battery chemistry to do this efficiently.
