Somewhat. OP also mentions generating energy from the pavement, which I don't think will ever be reasonable.

Solar car park covers are a great idea. Easier access than roofs, don't need to be water proof. Good cooling airflow underneath. Tend to be close to cities where power is easier to transport.

Solar parking lot covers are the best ROI solar installations I can imagine.

Surprised Telsa isn't doing this with their SuperCharger stations
