A most sensible idea, first one I see in EV context! The US and Australia are very different but for other places in the west I think fully electric driven for 100 km is to much. The combustion engine would grow along with the weight that grows along with the battery weight. Making the engine and fuel tank larger and would make them and the frame heavier which in turn would ask for a larger battery which asks for more hp again and so the circle continues. The lower limit seems safety which depends on the other clunkers [allowed] on the road. Solar seems a good way to add weight and strengthen the structure. Another sound idea is to swap the battery or parts of it. The bigger it is the harder that puzzle gets. I want to see swap while moving tech.
