Solar Roofing

One drawback to solar-generated electricity is the unwieldy panels, which look out of place on a traditional home. Now you can harness the sun's power right through roof shingles, thanks to a technology called thin-film triple-junction amorphous silicon. These space-age solar cells are shaped like conventional shingles and can be installed just like regular shingles, then wired into your home's electric system. Wilson says they're not as efficient as freestanding solar panels, but depending on weather conditions, they can generate virtually all the power for your home. In August, when the shingles are cranking out more electricity than you need, the current gets fed into the power grid, running your meter backward and thereby reducing your electric bill -- which makes up for rainy days, when output is reduced. Solar shingles cost $40 to $50 a square foot installed, versus about $8 for regular shingles, but you may only need them on the south side of the house. And many states are now offering generous subsidies. To learn more, visit eere.energy.gov.
