Project Sunroof

Project Sunroof is a solar power initiative started by Google engineer Carl Elkin.[2] The initiative's stated purpose is "mapping the planet's solar potential, one roof at a time."[1]

Project Sunroof primarily works to encourage the private adoption of solar energy by providing a set of tools to facilitate the purchase and installation of solar panels. Using data from Google Maps to calculate shadows from nearby structures and trees and taking into account historical weather and temperature patterns, the Project Sunroof website calculates how much money a user can expect to save yearly by making use of solar power.[1] In addition, the Project Sunroof website also provides a list of local solar power retailers capable of installing solar panels in that area.[2]


Project Sunroof was created by Google engineer Carl Elkin as a 20% time project. While initially launching only in the cities of Boston, San Francisco, and Fresno, the project is planned eventually to expand nationally or even globally, depending upon the project's success in its launch areas.[3] Google has previously invested in projects with solar energy provider, SolarCity.[4]

Solar power in Louisiana

Solar power in Louisiana is ranked 34th for installed solar PV capacity as of 2017 by the Solar Energy Industry Association. The state's "solar friendliness" according to Solar Power Rocks has fallen to 50th place for 2018 as the state credit program ends and other policy factors hamper market development. Taxpayers still benefit from federal incentive programs such as the 30 percent tax credit, which applies to business and residential solar photovoltaic and thermal energy systems of any size.

From January 1, 2008 to June 19, 2015, Louisiana offered a 50 per cent tax credit up to $12,500 for the installation of solar system for purchased systems, as well as a smaller credit for leased solar systems, which increased the affordability of solar PV and water heating. The state's legislature abruptly ended the credit program without providing full funding for eligible claimants, and a multi-year effort to resolve the funding shortfall ended successfully with signed legislation in 2017.

Google's Project Sunroof estimates Louisiana to have over 20GW of rooftop solar potential, of which New Orleans is estimated to have over 90% of its roofs capable of solar energy production.

New Orleans' largest solar array is the 1MW array installed by Blattner Energy at the Entergy Patterson facility in New Orleans East. The largest solar project in the state of Louisiana is currently the 1.2MW rooftop solar system at the Mall of Louisiana, completed in 2017 by Solar Alternatives and Strata Solar.
