Google now offers a new online service that is able to calculate how much money you will save using solar power, the company has developed a program through Google Maps that combines satellite imagery and the latest technology. It works by using the same resolution aerial photos that Google Earth uses, it then creates a 3D model of your roof and estimates how much money you would save in 20 years with the use of solar panels by calculating the size of the roof and how much natural sunlight has access to the panels.

"People search Google all the time to learn about solar, but it would be much more helpful if they could learn whether their particular roof is a good fit." Says Google's Joel Conkling. Learn more and watch the video below.
