Naive question: if we expanded a lot of residential and light commercial solar heavily enough, could the excess capacity no longer needed from the grid in the daytime be efficiently transmitted to where it’s needed?
Somewhere I saw someones study that said it's better to build solar and batteries than solar and transmission lines. I think wind is maybe more of an issue since wind and people don't line up geographically as much as solar and people.
I saw somewhere the opposite: that it’s better to build solar and transmission lines. So idk what the truth is.
