More steel and hence more co2 needed to support panels of solar carparks compared with rooftop or solar farms. Panels are higher, supports further appart and hold higher area.

Also extra costs of working in existing carpark - traffic control, cutting concrete for trenches etc

But you have benifits above the direct cost of electricity. Shade/ rain protection for customers.
