I'm an American, and it seems like a great use of land to me. This sort of a policy is particularly sensible in areas where it's hot, and there are extensive parking lots next to places that are mostly active during the day.
Instead of just having a heat island, you generate power to run AC in the associated buildings, and you also get shade for the parked cars.
There's a reason centrally planned economies are abject failures. People are incapable of anticipating all of the cascading effects of a "sensible" policy
I recently was at the Vegas airport, and what struck me was the parking lot.
It was the same parking lot I saw many years ago. But this time, instead of feeling sorry for the owners of the cars that were obviously getting cooked up, that whole are was shaded in bajillion solar panels.
It seemed like such an obvious win-win for everyone, I expect it to catch on fairly quickly.
