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?

    Another way to look at it: It used to be 20-25 years, so 10 is probably the best it’s ever been for ROI.

    Depending on the State power prices and tax incentives/rebates and your power consumption there are those that are getting 6-8 year ROI.
