Green Energy

That much would pretty much cover my usage in winter, summer I would be exporting the vast majority of it.

Which I probably should do, my provider gives not awful export rates. So might be worth just going pure solar for now and look at batteries later if export rates fall. IIRC it is like 60% or so what you would pay to buy energy you get for selling it. So if my panels make more than I use and I can shift a good amount of usage to daytime, free energy for a few decades after it's paid for the install.
