They quote £6,500 but is that for a panel or for an installation. Even if the latter, on their own figures, it'll take ten to twenty years to recover your investment.
Solar panels is certainly a major investment, but should pay back in a much shorter time than that.
We had ours put in a couple of years ago and their (conservative) estimate was that it would take 8-9 years to cover the cost. And I do think decent companies are careful not to over-claim - indeed we are generating about 10% more than they'd estimated.
And of course these estimates did not factor in the huge spike in electricity costs - so this will reduce time to break even further.
We have quite a few other people in our road with panels and about 9 years to recoup costs seems to be the norm, although it does depend on you having appropriate roof space that points in the right direction
