In a city the best place to put them first is roof tops. Rooftop solar has minimal structural requirements relative to parking lot canopies.

I think this might be partially an indirect tax on parking lots inside a dense city. It raises the cost of using land for parking, but does so in a way that provides shade and clean energy at the same time.

Ground level solar in a big city doesn't make much sense, they'll be getting a lot of shade- which significantly reduces the power generated. They've made new panels that are better with partial shade, but it's still crazy.

Most parking lots in big cities are not surrounded by high-rises.

		Well also when they are they are small parking lots. This regulation specifically is for big public parking lots. Also the "surrounded by high rises" locations are more likely to be built as parking garages in the first place.

		Low rise or high rise, (near) ground level (sub)urban PVs are going to run hotter because of the heat island and disrupted breeze, so panel efficiency and lifespan will take a non-zero hit too

High rises are expensive to build. The reason they are built in the first place is that land is even more expensive, and expensive land militates for parking garages rather than open parking lots.

Why do you assume they haven't been doing that already?
