You need a lift to maintain them and a crane to install them. What happens when someone drives into them? Do you have space for the infrastructure to hook them up to the grid?

You kinda answered your own questions there. You get a lift and a crane. Presumably whatever local company installed them would also repair them.

They don't have to be hooked up to the grid necessarily of they directly charge the cars parked underneath

[–] zxqwas@lemmy.world 4 points 2 weeks ago (2 children)

They only generate value when there are enough cars parked that need charging. How do you make sure that utilization is high?

Solar panels are expensive buy and install. They are good when they are used to their full potential. But installing them anywhere just cause it's a flat surface is not a good idea.

Covert parking lots to fields & sparingly cover them with solar panels?

This would work well in old mall parking lots -

[–] thorhop@sopuli.xyz 4 points 2 weeks ago

Because with how many parking lots there are in the US it would crash the cost of electricity by sending supply to the moon.

Can't have that. Oligarch lobbyism go brrr.

Or, or, hear me out. Deprioritize cars. Build public transportation/car free spaces/walkable cities, reduce/eliminate parking lots. Require smaller more fuel efficient vehicles. Build solar panels on rooftops/windowpanes. Plant and protect trees and other native plants.

cost. it's significantly more expensive to cover parking lots and roofs than fields, because somebody has to climb a ladder to install it.

also many places are already covering the parking lots. which is mostly as a marketing gag i suspect, or to produce the electricity themselves that they feed to the cars instead of having to buy it over the grid. which might be cheaper if the grid has high profit margins.

And roofs. And roads. And maybe roadroofs.

[–] mycodesucks@lemmy.world 3 points 2 weeks ago

Because if you put a roof over the lot trucks can't keep getting perpetually bigger and more expensive.

[–] zxqwas@lemmy.world 2 points 2 weeks ago

Those cost money. Installation cost go up and maintenance cost every year goes up because you need that equipment.

If you have any sense you put them where they are cheap to put first. Not where there is any free space.
