Simple calculation. If you pack solar panels on the giant flat roofs of shopping malls (and maybe add them as shade covers on the giant parking places AND add some big storage batteries, you can offer FREE charging for all EVs, cover most of the power usage of the complete shopping mall and on good days even sell electricity to the grid. Same for airports. What's not to like? cc @isotopp
@jwildeboer I would love to buy a fridge that has 1-0 control input informing about surplus from PV. We already have this for wallboxes. I know I can use a smart socket. But that is not the same. I have to control it from somewhere and when I cut the power I lose the light in the fridge.
