Think the person you responded to meant for the solar panels to be above the parking lot, not the parking lot surface. IIRC, Google has quite a far solar panels in their parking lots, where they not only generate electricity but also provide shade for the cars parked there. I've also seen a couple of rather massive solar panels in central Atlanta near CNN. I was told they were installed by Ted Turner because he has a penthouse nearby. No idea how much power they generate but it does provide some nice shade.
There was a different comment recommending parking lots, and i summed up all my thoughts in the comment above. To me it sounds like France could use some shade as well as some clean energy. Calling it quits is just not an option given the crazy heat waves of recent in Europe, and we should hold onto to anything that improves what we have right now even if by 1%.
