San Francisco Passes Law Requiring Solar Panels on New Buildings.

San Francisco Board of Supervisors member Scott Wiener released a statement yesterday (April 19, 2016) saying that the board has approved a law that will require newly constructed buildings to have solar panels installed on 15 percent of roof area. The effort will support the city’s goal to be powered completely by renewable energy by 2021.


The installation can include either solar PV or solar thermal panels and builds on an existing law that requires builders to ensure that at least 15 percent of roof space on new buildings be “solar ready.”

This renewable energy ordinance makes San Francisco the first major city in the country to require solar panels be installed on new construction.
