to its current share of generated capacity in the UK. i think were well on the way. serching the internet you can find fitted 4kw systems for A5200 which is a bargain even before the FIT. 2 years ago it was A14k add to that this weeks inflation busting energy price rises and you get a 1 way street, with a lot of solar panels on it!! given a few more years and solar will be the gold rush that property was in the last decade with a bust only coming when the price of power plummets. i for 1 look forward to this bust.
