> Why connect to the grid if you are self-sufficient?

I think that starts to bleed into the "pre paid meter" vs contract argument.

but practically the difference between total self sufficiency and 90% is willingness to fork out cash.

I currently have a 13kwhr battery, which covers my domestic power needs for 75% of the year. (we'll start to draw on the grid in the next few weeks.) but in the dead of winter it'll only cover 20-50% of my daily need (excluding the car)

but for car power, thats a different beast. Even though I don't commute by car, with the charging at home, I now use around the same amount of power as the uk average house. (even with solar and storage. pre electic car era. )
