Google Project Sunroof Launched to Calculate Solar Panels


Google has been influencing in go green campaign by contributing through their Google Green projects. Google Green initiative a lot, they had cut down their carbon emissions, their servers had been using 50% less energy and they invest $2 billion in the renewable energy. The latest Google Green project that recently launched is Google Project Sunroof. Google Project Sunroof has been launched on last August 17th 2015, allowed people to calculate their solar use and needs.

Recently the electric aircraft powered by Solar Cells had been launched by Airbus a month ago. It proves that solar cells is the solution for energy saving nowadays. The use of Solar energy by reducing the green house gases are the main focus worldwide.

Google Project Sunroof works with Google Earth, Google Maps, and other data gathered from the various databases. Google Project Sunroof is the Solar Power calculator, which calculates the Solar Power observed in the building and customizes the results for the user, how much area needs to be covered with the required Kilo Watt (KW) of power, how much that user could save by the implementation of Solar cells, and how much current electricity bill amount with the cost to implement the Solar Cells. In a simple word, Google Project Sunroof aims to help calculate the best solar plan for user.

As the price of installing solar has gotten less expensive, more homeowners are turning to it as a possible option for decreasing their energy bill. By then, a lot of people start to searching for how much actually saving cost that they made if using solar system for their house, and how much it cost to install the solar panel. That is when the idea of Google Project Sunroof has started. Carl Elkin, Engineering Lead for Google Project Sunroof posted on Google Green blog post :

“A typical solar home can save hundreds or even thousands of dollars per year on their electricity bill.  But, as a volunteer with the Boston-based solar program Solarize Massachusetts and a solar homeowner myself, I’ve always been surprised at how many people I encounter who think that “my roof isn’t sunny enough for solar,” or “solar is just too expensive.” Certainly many of them are missing out on a chance to save money and be green.”

Users can have the Solar Cells for a lease from a vendor and they can also purchase them. Google also provides the vendors of Solar Cells for the people to get started. So, when compared to the monthly electricity bill, the calculations by the Sunroof tool will show the lease amount for the Solar Cells with the savings. Google also provides options for the vendors to become affiliates.

The project Sunroof makes it easier for the people to start up with the vendors by providing their details. When the details are provided, the request for the Solar Cells layout will be sent to the vendor and they will contact the users regarding the Solar Cells installation.


Users need to fill this form, to share the details to the vendor.

Google Project Sunroof is Google’s effort to make solar power simple and understandable. Simply by entering address into Google Project Sunroof’s website, Google can show how much usable sunlight that can be get per year, which parts of house get the most sun, how much room for solar panels, and most importantly, how much money would save by switching into solar panel.

Currently Google Project Sunroof only able to use only in the US cities of Boston, San Francisco and Fresno. Google says that they are taking measures to make this available all over USA and world-wide. However, as the Google Project Sunroof is not available in every country yet, people who are living outside Boston, San Francisco and Fresno can provide their email and zip-code. Once the Google Project Sunroof is available in their area, they will be notified.

When the user search for the address on the Sunroof website, Google will automatically shows the area by several colors. Yellow shades means the area exposed to the sunlight, magenta color indicating the Shadow (shades). It takes into the nearby trees and buildings in plotting the 3D-model to represent the sunlight and the shades.

Don’t worry, Google Project Sunroof doesn’t give the address to anybody else unless the user ask for it. Google Project Sunroof will only send information that user has been provide to solar providers that they selected.
