Alvarado Elementary School Solar Array
Location: 625 Douglass Street
Size: 50 kW
The 180-panel system is the SFPUC’s first school installation. The array will provide up to 20-to-30 percent of the school’s electricity needs, producing 62,500 kW hours of electricity, the equivalent of removing about 24,270 pounds of carbon dioxide or 4,500 gallons of gasoline from the environment annually. Installations are planned for additional schools both to reduce the City's carbon footprint and to educate students on the importance of environment stewardship.

MUNI Woods Motor Coach Facility Solar Photovoltaic (PV)
Location: 1095 Indiana Street
Size: 107 kW
This 336 module solar array is the SFPUC’s first installation on a MUNI facility. The modules are installed on a customized solar racking system, which can be seen from HWY 280 if you look closely enough (viewing recommended for passengers only, not drivers). The generated clean, renewable energy is fed into a SatCon inverter before it enters the grid. The MUNI Woods Motor Coach Facility performs light and heavy maintenance on MUNI’s bus fleet

Muni Solar

Chinatown Health Center Solar Photovoltaic (PV)
Location: 1490 Mason Street
Size: 24.5 kW
With excellent sun exposure and approximately 77 modules installed, the Chinatown Public Health Center Solar Array is the SFPUC’s second installation on a Department of Public Health facility. These ultra-efficient, SunPower modules are installed on a customized, non-penetrating racking system. The rooftop array is situated four floors above the Broadway Tunnel and offers stunning views of San Francisco’s Downtown and piers.

Sunset Reservoir Solar Array
Location: Sunset Reservoir
Size: 5 Megawatts
The Sunset Reservoir Solar Array is San Francisco's largest solar installation. With a generating capacity of up to 5 megawatts, the Sunset Solar Array was the largest, urban, municipal solar array in California when completed. The Sunset Reservoir Solar array more than tripled the amount of municipal solar generating capacity in San Francisco.

San Francisco International Airport (SFO) Solar Photovoltaic (PV)
Location: Terminal 3
Size: 456 kW
SFO is San Francisco Water, Power and Sewer’s largest retail customer and Terminal 3 houses a large single-roof solar PV project. The Power Divisions solved the challenge of designing a module layout for the circular roof by using a unique mounting system that allows a full 90 degree “tilt up,” which eases future inspections and cleaning. Visitors to SFO can easily view this entire installation from the Air Train.

Chinatown Public Library (PV)
Location: 1135 Powell Street
Size: 10 kW
The solar photovoltatic (PV) system is installed on the roof of this historic building located in the heart of San Francis’s Chinatown. It is an important example of success in providing clean, reliable solar power while not compromising the integrity of a significant cultural landmark. The metering system reports on the performance of the installation and provides library patrons the opportunity to learn about solar power.

City Distribution Division Photovoltaic (PV)
Location: 1990 Newcomb Ave.
Size: 134 kW
The City Distribution Division installation uses lightweight, high-efficiency crystalline PV cells embedded on the roofing membrane. The resulting module provides power output comparable to regular modules, while satisfying the very limited maximum weight allowance on the roof.

Solar at CDD

North Point Solar Photovoltaic (PV)
Location: 111 Bay Street
Size: 241 kW
Adjacent to Pier 39, two separate building roofs were used to provide supplemental solar PV power to this important agency facility. This building complex serves the residents of San Francisco during wet weather by treating wastewater and storm water. The equipment was designed to resist corrosion from the salt air and other harsh environmental factors.
