Well so far it’s saved money off our electricity bill. Anything that we don’t use goes back to the grid and then offsets our gas usage. To me it’s worth having. Bearing in mind I haven’t paid for the installation at all, as it came with our property. So far with the tariff we’re on, and taking into consideration the difference in weather we usually send back to the grid £35 to £50 a electricity a month.
Thanks for the lengthy reply even if j wanted to, I'm not I'd be allowed to do it on a new build
