Sramana Mitra: Deal Radar 2009: Sungevity

Sungevity uses the Internet to offer its customers an easy and affordable way to buy and install solar rooftop panels. Customers only need to provide their address and some information about their current electricity usage and bill. In less than a day, with the use of satellite data, Sungevity studies the possibilities and comes back with a quote, telling them what their electricity savings over the next few years would be and how much of their electricity bill can be converted to solar energy, and showing illustrations of what their roof would look like with the solar panels on it.
