Google Sunroof project, will help you find out how well the solar panels will work on your roof. The company launched the project in August, but at that time it only covered the house in Boston, and a few selected areas of California.
Now, Google is expanding coverage Sunroof, to select metro areas in several additional regions.
The project now covers a number of areas in California, Massachusetts, Arizona, New York, New Jersey, Nevada, Connecticut, Colorado and North Carolina.
Once the user enters the address, it will be able to know how many hours of useful sunlight it can be expected to select the number of panels and how much it could save by installing solar panels.
Google says it uses a special database that helps him evaluate the orientation of the roof, the height of nearby trees and other buildings, as well as the local weather conditions to see how well the solar panels will work on the roof.
If the user decides to install solar panels, Project Sunroof also show a list of local companies that provide these services.
