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.

That crane and lift sounds expensive and cumbersome. I'll just put the panels on ground mounts and buy more solar instead.

[–] rbos@lemmy.ca 1 points 2 months ago

That's totally a decent option. Unless you want the space under it for cars or something, of course.

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 months ago (1 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.

[–] Pirasp@lemmy.world 1 points 2 months ago (1 children)

Factories and other places like that could easily size the solar plant to their normal needs. Sure, doesn't make sense to build every parking space like that, but some could definitely benefit

[–] zxqwas@lemmy.world 1 points 2 months ago

Put it on the factory roof and you don't have to worry about someone driving into them. Could be safer to maintain and inspect to depening on roof design.

Does it move? No.

Is there an are nearby where you can put them? No (unless you count on the roof of the adjacent building)

Answer: Sure
