You are assuming some weird scenario where we build out local solar, with none of the other components in place. Obviously, anywhere that local solar would be installed would be accompanied with bi-direction meters, micro-inveters, and possibly even local storage.

As for grid vs. local, decisions would be made based on cost, land availability, the grid itself. This will take years and more innovation. You keep glossing over that point where I say this is not a today thing, but something that could happen over decades. Please explain how you k ow what technology will be available 1-2 decades from now?

I am just a web developer, and my point about the company I work at, is not that I am some electricitiy expert, but that I hear the challenges brought up frequently in conversation and company meetings. These are main issues being worked on as we speak, but it is a slow-moving process. And again, solar is only 3-4% of electricity, so all the other stuff that is needed, will be worked on as we scale.
