I think it’s just way more expensive than you’d want. The schools here in California do it, and the steel superstructure is huge. Having done some steel moment frames for housing—let’s just say the cost isn’t in the panels. The moment arm for wind loads etc is not in your favor. My guess is you’re paying the cost of >10-20 panels to get 1 installed. Let’s call it a 15x cost multiplier. Even rooftop solar, which has a way worse multiplier (~4x) than power stations (2x?) can be hard to justify for some. You’re much better off covering the roof of the Walmart in panels than the parking lot. Which is why that is the case. Yeah it’s a better use of land, it keeps the cars shaded, but no one seems to have figured how to do it economically. Even in Southern California where it’s very sunny, and power is very expensive. I just don’t think it’s anywhere close to being economical. And in other markets the economics are almost certainly worse. |

Mass-production is the key to economies of scale. Government policies can play a huge role in steering us towards goals like that.
Why is America so rich? Because of car-industry. And why is car-industry so prominent? Because of the interstate highway system.
