We Should Put Solar Panels Above Parking Lots
Why Putting Solar Canopies on Parking Lots Is a Smart Green Move
A typical Walmart supercenter, for instance, has a five-acre parking lot, and it’s a wasteland, especially if you have to sweat your way across it under an asphalt-bubbling sun. Put a canopy over it, though, and it could support a three-megawatt solar array… the canopy would [also] shade customers… If Walmart did that at all 3,571 of its U.S. super centers, the total capacity would be 11.1 gigawatts of solar power — roughly equivalent to a dozen large coal-fired power plants.
It is more expensive to build the solar arrays and infrastructure above existing parking lots (compared to an empty field) but it is a great use to space. We should be encouraging such development.
