If we are serious about making cheap, reliable solar energy available to all, we would do well to follow France, by mandating solar canopies on ALL existing parking lots larger than 75 spaces within 5 years. Add on-site BESS +Vehicle-2-Grid chargers and you've very rapidly deployed a robust, widely distributed matrix of reliable micro grids generating, storing & re-distributing cheap renewable energy right where most of us live & work. No new utility transmission, interconnection, site acquisition, or other site improvement spending required. We have already made generous IRA investment incentives for this purpose available to wealthy owners of large leased residential & commercial properties with big parking lots. Just make them use it, like France. This policy would fix the glaring mismatch between the self interest of wealthy leased property owners and their tenants, who pay the utility bills. The benefits are obvious to all the owners of new health care facilities in my county, because they've already covered 80% of their parking with solar canopies. They get it.
