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?

They’re usually rated 20-25, but I think I read recently that some are still producing useful power after that.

Read an article on an early adopter that had over 30 year panels. They reported it was still producing around 70% of its original rated power.
