After looking at the design of solar vehicles for a few years I have found it is a numbers game. If you look at the battery frame and all parts of the S model it's designed to come in at around 4600 pounds. What if we reduced the battery to 25 to 30 kw. Used smaller tires and wheels. Lower body with a 3kw solar panel. If you could get the weight down to 1700-2000 pounds you would still have a range of 300 to 400 miles. To get the range needed for the S model they used more batteries. What if the mind set was to make a light efficient vehicle instead? To fit the the solar panels it would have to have a 20 foot long roof with a width of 7 feet. This might be a good size for a small RV. In any case there are aluminum RV's that are just a little bigger that weigh 3000 pounds. At that weight we are looking at 100 miles range. So getting weight down is essential. I think it could be done with a lightened Tesla skateboard. I'd be surprised if someone doesn't just do it with a wrecked S. Just spit balling. Still focused(mostly) on the solar trike project.
