A probe by consumer organisation Which? caught 10 out of 14 installers overstating potential savings from the systems, which cost an average of £5,500 and use energy from the sun's rays to provide hot water.
The organisation said most of the firms involved in its investigation were "true cowboys".
Last year, the Office of Fair Trading (OFT) received 1,000 complaints about the solar panel industry – equivalent to one for every 100 UK homes fitted with the systems.
Which? said two firms, Everest and Ideal Solar Energy, used "dodgy sales tactics" and "hugely overstated" the potential benefits of installing a solar thermal system. An independent expert calculated such a system would cut about 10 per cent from the Which? household's annual gas bill, but Ideal Solar Energy quoted savings of 50 per cent, while Everest quoted a 43 per cent cut. Everest also claimed the home owner would save £35,000 over 20 years, a suggestion Which described as "a massive exaggeration".

Sounds like a rip off at best. İn the US İ believe the system would be less than 5500 in dollars.
