I think you misunderstood the parent, they said "solar covered sidewalks" that shade pedestrians, so roofs.

Solar roofs on car parks seem good to me; better than using pasture land converted to solar farms which I'm seeing more and more in UK.

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

Yeah solar roofs on car parks is pretty good because the shade aspect is just a bonus.
