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 …
We have a national grid that is shared by all power companies, and is open to all. Power companies just buy and sell power on the grid based on a spot pricing system. Because of this, we have very easy movement between power companies, and have dozens to choose from, leading to a lot of competition. Mine is a tiny company that specialises in solar, having sell to grid rates well above most companies.
The company that did our solar install had their top recommended companies, they worked out the best for us, and organised getting set up with them. Was I pretty nice experience to have everything taken care of like that!
4 years ago it was 18c per kwh. Which was nice.
Yours is very good. and selling back to the grid would be nice! Making me jealous lol.
I’m feeling very lucky now!
