I think parking lots are the ideal place for large scale solar. They have already destroyed the local environment, and anything shading black asphalt will be an improvement for local temperature.
Other plusses are that they are close to electric demand (business, homes, and EVs), and people prefer to park in shade.
The downside is there's no existing structure to install the panels, so that's more steel used to mount the panels.

There are numerous examples of that around where we live, in the foothills of the mountains north of Phoenix, where there are also lots of recent modern construction projects. One nice installation at a school a few minutes away has the panels on structures providing shade, all over blacktop, as you thought of.
