Solar Installations

We are responsible for the installation, maintenance and operation of the City’s eleven municipal solar installations. In total, these energy facilities can generate up to 7.2 megawatts of energy. Currently, we are actively planning and preparing for the installation of additional solar sites in San Francisco.

 

Sunset Reservoir Solar Array
Location: Sunset Reservoir
Date on Line: November, 2010
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
Date on Line: March 12, 2008
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.

City Distribution Division Photovoltaic (PV)
Location: 1990 Newcomb Ave.
Date on Line: December 27, 2007
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.

Pier 96 Photovoltaic (PV)
Location: Pier 96
Date on Line: January 2, 2007
Size: 245 kW
This solar PV installation provides clean, green power to the water recycling works at the Norcal recycling facility. During construction, strict safety measures were employed to protect workers on the extremely steep roof. Module performance has been improved by it location, which extends out over the San Francisco Bay.

North Point Solar Photovoltaic (PV)
Location: 111 Bay Street
Date on Line: December 27, 2007
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.

Maxine Hall Neighborhood Medical Center (PV)
Location: 1301 pierce Street
Date On Line: December 4, 2007
Size: 32 kW
San Francisco Water, Power and Sewer installed a small, but important solar array on an important Medical Center and Clinic in the Western Addition neighborhood. A computer screen in the lobby provides Medical Center patients a real-time readout on the installation’s performance.

Moscone Convention Center (PV)
Location: 747 Howard Street
Date On Line: March 15, 2004
Size: 676 kW
This installation represents San Francisco Water, Power and Sewer’s first and largest “combined roof’ project to date, consisting of over 5,400 modules. The DC power generated from the PV arrays located on the Esplanade Ballroom and South Lobby roofs are converted to clean, green AC power using three 255 kW inverters.

Southeast Water Pollution Control Plant (PV)
Location: 750 Phelps Street
Date On Line: October 6, 2005
Size: 255 kW
This installation is situated on the roofs of two wastewater treatment buildings. Clean electric power is generated 365 days per year on site, efficiently and reliably, supplementing other electrical power at this large plant, which treats 70 millions gallons per day of San Francisco’s wastewater.

Chinatown Public Library (PV)
Location: 1135 Powell Street
Date on Line: January 8, 2008
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.

Chinatown Health Center Solar Photovoltaic (PV)
Location: 1490 Mason Street
Date on Line: December 15, 2011
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.

MUNI Woods Motor Coach Facility Solar Photovoltaic (PV)
Location: 1095 Indiana Street
Date on Line: December 15, 2011
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
