It's an interesting thought exercise, but the quick short term solution would be a 5kWh buffer battery just for the evenings to save buying at peak times.
I started that way before going fully off-grid to avoid subsidising the fossil fuel industry here. Plus ~70% of my bill was fixed charges, and they wouldnt pay for excess solar generation above what I used.
I think this sort of mega home battery bomb could be avoided through legislation by offering free grid connections. So I 'pay-in' 10kWh today, and maybe my account is credited with '5kWh' for later use. I'm sure we would see a much bigger uptake of home solar with such a scheme.
