It’s better for them to ne on the grid instead of each having their own panel and battery. It’s more efficient material-vise, and they would still need to be connected to the grid.
I’d still have them on roofing. Might just be easy to deal with a council and expand the system across a town or city. On homes people tend to have to buy the panels themselves (£8-20k for a system), then they individually have to negotiate with their energy supplier - who can deny them the option of connecting to grid.

I’d put panels on all roofs, though.
