Well I think I have a winner, I have another company coming at 08:30 so unless they can do something 'extra' I have a mind to go with this quote.
4kw Solar Panel System (10 panels)
5.2kw Giv Energy Battery
Giv Energy Inverter
£9,746 there is an option to go to 450W panels for an extra £50 each
All the ones who have used Google Earth say they can supply 12 panels, all those who have visited say 9 or 10 panels, I still think it's expensive, that the installation costs are too high & I hate having trades in/on my house it's a trust issue I know.
I'm sure I could do it, but this way hope it gets done 100% right
is it a hybrid inverter?? or dont you want grid back-up??
