I don’t think any meaningful storage makes sense for a home, but for a grid-attached solar plant. The surface area is large but I think the cap ex (and naturally the op ex) are naturally much lower.
Even if the solar plant doesn’t generate enough in the middle of summer when demand is high, its grid connection means the batteries could be charging from surplus wind at night.
Not that this addresses my time-volume issue, just saying it’s not worth considering from the single home perspective except in unusual cases.
I'm hoping for HVDC both across both large spans of longitude and lattitude, that would be a game changer. There is plentiful solar, all we need to do is to be able to transport it across the planet to wherever the sun currently isn't shining.
'A mere matter of engineering'. But we do have that capability.
