'Free' solar panels are not a great deal, says Which?

They found that householders could save as much as £10,500 over the next 25 years by buying their own solar pv panels (to generate electricity) instead of signing up to a scheme offering 'free' solar panels.
Even in the sunniest corner of England, 'rent-a-roofers' would only save a maximum of £412 a year off their electricity bill, whereas the company supplying the solar panels would get £1,313 from the government's feed-in tariff incentive scheme.
Which? experts found that if consumers took out a (Which? Best Rate) loan to cover the installation cost, they would still be thousands of pounds better off in the long run. It has a great little illustration showing savings you could make depending on which area of the country you live in.
This finding from Which? comes to the same result as our own calculations on the rent-a-roof scheme. Our concern is that unless householders are big daytime electricity users they won't even see much reduction in their electricity bill.
