Calendargirl
We had our solar panels professionally installed nearly 7 years ago. Cost us £5500. Have had about £4500 back in FIT payments so far.
The money was earning peanuts in the bank/building society.
The fitters said our roof was ideal, south facing, not shaded from trees, neighbours roofs etc.
The payments were lower than if we had had it done years earlier, but the installation costs had gone down in the meantime, so evened out I suppose.
Same here Calendargirl, ours were installed April 2014, cost £5,500 & we’ve received £6,100 FIT payments to date. We’d got a quote a couple of years earlier but it was extortionate & we didn’t want to commit too much of our savings.
I’m careful to run my washing machine, tumble dryer, dishwasher etc at the sunniest time of day, and never run them together. Must admit that our electric bills have really benefitted and are much lower than they used to be (&compared to family bills) in terms of kWh billed.
Mind you, we’ve changed most of our lightbulbs for LED or low energy now & changed the ageing 250w security light which seemed to be on half the night, so I bet that’s helping!
