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 …
It’s also important to check whether solar overcacity is worthwhile in the UsA. Her3 it is not( anymore).
I’ll say generally speaking in most places it isn’t, however, once you go solar, you may increase your electricity usage as you move away from carbon based energy. Before solar we had natural gas furnace heating and two gasoline cars. Now we have two EVs and a cold climate heat pump with zero natural gas and zero gasoline consumption. So I wanted the larger solar capacity to cover the increases in electricity we knew we’d have.
Its worked out pretty well. We have fairly large electricity bills ($400ish) in Jan and Feb, a small bill in March, and usually a tiny bill (under $10) in April. Then no bills for the rest of the year. Also keep in mind that is TOTAL energy costs, no gas or gasoline bought anymore.
Yes , I can see how that impacts the process. indeed checking the rules and doing some prior info digging is essential.

nicely done.
