MOUNTAIN VIEW (CBS SF) – Google researchers say a lot of people have been asking the company’s algorithm how many solar panels would fit on the roof, how much energy they could produce and which contractor should be hired to get them installed.

Google will even provide an estimate on how much you could save over a 20-year lease and give you some options for installation. The feature is currently only available in a handful of markets, including the Bay Area and Fresno. Check out this link to see how much potential Project Sunroof thinks you have.
