AC Transit

The Alameda-Contra Costa Transit District (AC Transit) public works project involved a 510 kilowatt (kW) roof-mounted solar photovoltaic (PV) system on the transit district’s maintenance building in Oakland, California The AC Transit serves the diverse community by operating out of four yards located in Richmond, Emeryville, Oakland and Hayward. The Oakland-based maintenance yard houses a PV system for the transit district designed and built by Cupertino Electric. The solar energy system will help reduce the transit district’s operational costs by utilizing alternative energy and a non-penetrating module/racking system. Cupertino Electric assisted with the solar energy engineering of this project.

The electricity that's generated by the photovoltaic system is significant enough to offset the electricity used to create the hydrogen that powers the transit system’s hydrogen-powered buses that run throughout the East Bay.
