Website lets homeowners instantly determine the solar potential of their rooftops

Solar power, meet online shopping. By simply typing in an address on Geostellar's website, property owners can view an instant analysis of the financial savings and carbon offsets they can expect by making the switch to solar power. The site even lets them compare system designs and pricing estimates from local installers and schedule an installation from home. Think of it as a Google Maps-meets-Expedia platform for renewable energy.
