I recently helped an old school friend - now living in Chelmsford - plan his energy needs during a big renovation development on his house and, just like I told him, if you're looking at renewables then it makes the most sense to look at a "whole house" solution.Thanks all.
I've looked at our usage and it seems we are running at around 3kW PA at the moment.
We fully LED'd up as of 3 years ago as I replaced bulbs as they went and replaced original bathroom / kitchen fittings at the end of life and have a fairly modern house (20 years old).
It sounds like batteries and taking advantage of cheaper energy could be the way to go if the maths works.
I guess in the future, when electric boilers take over from gas when they are phased out, electricity demand could well be higher and solar panels will make more sense.
In the end we got him fitted a 12kw Mitsi Ecodan air source heat pump (told him to wait for the new Vaillant which is amazing but time constraints stopped that) with 4kw of solar and 5.1kw of battery storage. Capex was circa £18k but he'll receive just around £11k plus inflation back via the RHI. I also got him on a grid trading tariff but that's still quite new so we'll see how that pans out.
