Covering large parking lots with solar panels is an idea that goes back decades but in America at least it’s an idea that has never really taken off.
What is the reason for that? Is it due to the overall cost or is there something else that keeps Walmart, Target, Costco, Sams Club, Malls, etc. from covering their parking lots with these panels and selling the power?

Supports are nothing compared to the electrical infrastructure needed to actually use the solar power. Adding solar to a commercial 3 phase switchgear is a massive headache.
