New solar shingles said to have 10-to-12-year payback

The Dow Powerhouse Solar Shingle is placed just as a normal roofing shingle would be. Installation of these solar shingles would cost the homeowner an additional $10,000, though the price of the products is expected to fall. The shingles can save 30 percent to 40 percent on utilities costs, and the roof will pay for itself in 10 to 12 years.
