Some one I know has been offered a solar panel deal
The information I have been given is that the panel installation would normally cost 10k
At that rate it would pay for itself in ten years due to a combination of electricity not paid for and inconme from the excess going into the grid they say
They are offering the panels for 250ukp and say that they make their money by taking the money from the excess going into the grid
My current electric bill is about 80ukp per month
How big would the panels need to be to generate in excess of this usage?
I cannot see how this could ever work so can some one please explain
Regards
