These posts are timely.
We have a 4kw panel and a 2.7kw pythontech battery.
We buy power from Octopus: they are very flexible, i'm significantly in debt to them, so far their position is "it should even out in the spring". Octopus customers remain in total control of their direct debit, both when and how much per month.

Earlier this week I had a conversation with a technical representative from the Renewable Heat Partnership.Long story short the advice was to increase the battery capacity to 4 x 2.7kw = 10.8kw, which is enough to run the house for 24 hours in winter
and a couple or 3 days when the PV panels are working. The batteries would be charged from off peak power and/or the PV panels. Our gas boiler is getting old, though it still works well. To go to an air source heat pump would involve a nett outlay of £10k, so we should aim to keep the gas as long as possible and might consider a new gas boiler in 2024, rather than a heat pump, but if grant support goes up to, £10k then er should jump. There is noise about increasing the grant as heat pump uptake isn't enough to meet Government targets..... so watch and wait.

A refreshing, factual conversation by someone who wasn't selling anything.
