At first glance that may look like a flat plate, but the edges are rolled, there is an overall crown and a reflex curved aft. It's like a Morelli shape that swallowed a solar panel.
The necessary wheel penetrations on the bottom aren't any problem, but a tandem two-seater cockpit canopy would be. People want their view of the countryside, can't sling them underneath.
Needs better solar panels, like ones that absorb infrared that is re-radiated from the road or even after dark:

Here's another one, capturing the blue part of the spectrum through re-radiation in a hydrogel:
This New 'Green' Antenna Could Double Solar Panel Efficiency
So — blue absorbing panels on the top, and infrared absorbing panels on the bottom.
