YEA GODS that is expensive
we have not got ours yet but it is a lot less than that
and I am not sure our panels will charge even that!
Personally I would suggest a system where you can get a couple of smaller batteries and see how it goes
but with the ability to lob anotehr one or two in when you get a better idea of what you can charge

Remember, we have a 10.4Kw system. It will certainly charge that easily for at least 3 seasons.Yesterday, we produced 32.3Kwh, and used 13.2 - and yesterday was relatively low production, it was actually cloudy here for most of the day - and the 13 was only so high because we put the immersion heater on to use it up.

Right so another question for the more experienced.
As we no longer have a tank in the attic or an immersion heater (we changed to a Combi about eight years back) does it make the changing to Solar less cost effective. I.E. we will still be firing up the gas boiler when we want water.
Or does that just mean that any electricity produced will just power other appliances for longer before running out and switching to supplier electricity?

132kw/h used in day - thats a lot lol

That depends on whether you are generating more than you use for most days. If you are, then yes, it will be a little less cost effective. But if you are still taking some from the grid most days, then it doesn't make much difference.
How did you guys find your installers? I am interested in a system for an East West roof, with hot water diverter and maybe batteries, although thinking of switching to an EV can in the next few years so presume by then the car can be used as a giant battery. I just don't know where to start in getting accurate predictions and finding now cowboy installers.

We took out a trial subscription to Which?, read their articles on Solar, and then contacted a few of their "trusted" installers for quotes.

If you generate more than you can use then the excess can be sent to the grid for other people to use
Which is nice and moral and all that and reduces the overall need to making electric from fossil fuels (by a little bit)
Luckily there is a Smart Export Guarantee which allow you to register with some of the energy companies and they will pay you for the excess. The rates are a lot less than you pay for electric you get FROM the grid but it is something
Currently I think Octopus pays the most but it varies so you need to check
Not much else you can do if your not using all your leccy ? Other than switch it off ? Seems daft not export it if you can ? Anyways looking around my street I’ll need to knock on doors . I reckon depending panel sizes . There is a chance of at least 16 panels on mine
If your considering batteries in the future make sure you look at hybrid inverters or you'll need to change it later
Yeh i will get a full quote for everything…..the decide which option to take. We may even take a further lump sum from her nhs pension to top up the financial package we have available
we are also going to get new windows and doors fitted at the fromt of the house, the back was done before i bought it 7yrs ago.
