Just had a young chap at door to see if interest as we are south facing, wouldnt normally give door salesmen time of day but he was lovely and polite and a bit dishy and today im a bored housewife. Anyway me and dh have talked about it in past and am wondering whats to consider. These were free so they like hire your roof space for 25 yr and what you dont use gets fed back into grid and they get money like that, we just get free leccy in daytime. Does anyone here have them and have a better system where they get free panels/ leccy and some moeny back? or are they just a waste of space and hassle?
