Google Project Sunroof is a new tool that lets you calculate your home’s solar power potential. Now you can compare what you are paying currently with your utility versus installing solar panels on your home and you can compare the cost.
Project Sunroof, a tool that calculates your home’s solar power potential using the same high-resolution aerial photos Google Earth uses to map the planet. After creating a 3-D model of your roof, the service estimates how much sun will hit those solar panels during the year and how much money the panels could save you over the next two decades.
Project Sunroof also simulates the shadows that typically cover your home on any given day and it tracks local weather patterns.The service relies on public utility rates in your area.
