    So like any ceiling with HVAC, etc?

    Yes, but HVAC systems rarely have to cover an entire parking lot. There’s a lot of attendant infrastructure that comes with it. Compare that to dedicated rural solar fields, where you don’t have to worry about people wandering in and around the panels. Its not a deal-breaker, but it does raise the unit price.
