How big a solar battery do I need to store *all* my home's electricity?
shkspr.mobi
I have a modest set of solar panels on an entirely ordinary house in suburban London. On average they generate about 3,800kWh per year. We also use about 3,800kWh of electricity each year. Obviously, we can't use all the power produced over summer and we need to buy power in winter. So here's my question: How big a battery would we need in order to be completely self-sufficient? Background …

Neat breakdown with data + some code.

    Ok, to be polite, you were just mistaken in portraying a 1 mwh battery as a reasonable idea. It is just so absurdly stupid that motives for the proposal need to be looked at. I accept your admission of stupid instead of evil.

      I’m sorry you didn’t read my article. If you had, you would have seen me say…

      Remember, this is just a bit of fun. There’s no practical way to build domestic batteries with this capacity using the technology of 2025.

      And

      Is this sensible? Probably not, no.

      And

      remember, this is an exercise in wishful thinking.

      At no point did I say it was a reasonable idea. I went out of my way to demonstrate how impractical it was.

      I accept your admission that you didn’t read my post means you are stupid rather than evil etc.

        But there are sensible paths to going off grid. Why you would write about an impractical fantasy path was my puzzlement.
