Homeowners are increasingly turning to solar panels to secure cheap electricity and make a profit, according to Eco Environments.
David Hunt, sales and marketing director at the company, said: "Most people are looking at it now domestically because they are going to get two or three per cent on an ISA or out of the bank account, but with the solar they can get 15 per cent.
"There are reduced energy costs and the return on investment; that is what is driving the domestic market," he pointed out.
For many people, the financial incentives to fitting photovoltaic panels to homes outweigh the environmental benefits, particularly as energy suppliers continue to hike their prices.
Most customers "like the fact that there are green benefits, but they are doing it because their energy prices are going in one direction very quickly", Mr Hunt added.
His comments came after housing minister Grant Shapps announced that green homes do not have to be 'eco-bling'.
