Sorry don't want to come across as crass but what's the ballpark figure for getting that all installed? You talking high 4 figures or 5 figures? I take it it's a 10 year ish payback?
It cost me orginally 17k but with vat cut 16k but 8k of that is the battery (to be installed yet) so 8k Ish for 12 panel set up
With battery 8 year payback as I'm high usage
