Solar is not coming to a government parking lot near you unless these hurdles are addressed. In the very least, not "all" government parkinglots.
It actually annoyed me a bit because my childhood elementary school is in my neighborhood of houses. And they constructed large metal structures in the parking lot and installed the solar. It's basically massive metal commercial metalwork, in a residential neighborhood. A bit weird.
What it usually doesn't have is 6x6" metal columns going up 20' into the air, and then diagonal metal roofing with solar panels on it.
Go ahead and try to get a permit to install a metal carport in front of your house in a normal town. I don't think you'll get it because it looks ridiculous in residential. But somehow they okd industrial metal solar installations in my neighborhood.
Definitely weird and not at all something we expect other people to live with.
And a substation might be required, so I guess bring it on. Solar panels in a parking lot could be done anywhere. Why install them in the parking lot in a quaint residential neighborhood? Why not just put them near city hall or any land the city owns but isn't in residential?
I get it, but I don't think it was really necessary or any more useful than solar on tons of other locations. The city is going to pay for x amount of electricity one way or another. They could have stick that solar in the bus terminal parking lot in the commercial side of town.
