The subsidy given by the UK government drops dramatically at the end of the year. With new panels getting smaller all the time and more efficient I have decided not to bother for now. Existing panels are large and have a finite life.
I have decided to wait, especially as our electricity bill is already very low because we use LED and economy lights widely. I think the government should be doing far more to encourage the take-up of energy saving measures. This is surely a "win-win" approach?
