Google has introduced Project Sunroof, an online tool that will help homeowners to find out if their roof is good enough for solar energy installation.

Project Sunroof uses high-resolution aerial mapping and computing resources to help homeowners calculate the roof’s solar energy potential without having to engage into any sort of complicated process.

According to Google, it wants to make installation of solar panels easy and understandable to public.

Project Sunroof analyses the solar energy potential through 3D modeling of the roof.

The tool uses Google’s database of aerial imagery and maps, shadows cast by nearby structures and trees, sun positions over the course of a year, along with historical cloud and temperature patterns in order to find out if the roof is suitable for solar panel.

The online tool is now available in the area around San Francisco, Fresno in California and around Boston, Massachusetts and users in these regions can enter their address to figure out the solar energy potential.

According to Google, Project Sunroof is capable of helping users generate close to 100% of their electricity use, based on roof size, the amount of sun hitting the roof, and the electricity bill.

It also uses the present solar industry pricing data to run the numbers on leasing, taking a loan, or buying solar panels for the house to help customers make the right choice.

Google engineer Carl Elkin said: "Google has always been a big believer in zero-carbon energy, and solar power has been a central part of that vision — from accelerating the growth of rooftop solar, to helping finance the largest solar farm in Africa, to building one of America’s biggest campus solar arrays here in Mountain View."
