SolarCity has signed to develop four rooftop solar projects, totaling 6.9MW, at Air Force family housing in four states. The constructions are about to be completed and will start producing clean electricity for the communities.

The four rooftop installations are all for residential communities managed by Balfour Beatty Communities at Travis Air Force Base (AFB). The projects, which are completely designed and built by SolarCity, include the 3.5MW Luke AFB project in Arizona, the 1.4MW Tyndall AFB project in Florida, the 1.1MW Sheppard AFB project in Texas, and the under 1MW Travis AFB project in California. SolarCity will manage all the systems in the future.

“These types of partnerships leverage private and community resources to produce a win-win scenario that mutually benefits all partners,” commented Congressman John Garamendi of California. “This project will save taxpayer money, help build long-term sustainability into the base, and is strategically smart for our military, our environment, and our nation.”

These installations responses to and takes part in U.S.’s SolarStrong initiative, which creates jobs across the nation by constructing solar projects to improve the life quality of people as well as the development of solar power. SolarStrong initiative also encourages solar developers to hire veteran to build solar projects.

The four installations comprise over 26,000 solar panels and will produce enough power for more than 2,000 housing units.

Furthermore, the completion will bring Balfour Beatty Communities’s solar portfolio to 40MW. All of the projects are for military.
