Install a Solar Photovoltaic Roof to Generate Free Electricity
Terri Suess and Cheryl Long discuss how you can save money and reduce pollution when you install a solar photovoltaic roof.
Who would ever know this roof is a solar electric power plant?

Uni-Solar's breakthrough solar electric roofing comes in rolls or shingles and can be applied directly over plywood. A thin layer of amorphous silicon generates the electricity. The silicon is applied to a stainless steel foil and then coated with a flexible, weatherproof polymer.
Even a south-facing porch can provide homemade electricity.
