The Alameda Free Library Is Solar-powered!

Thanks to funding under the American Recovery and Reinvestment Act of 2009 and a significant rebate from Alameda Municipal Power, the Alameda Free Library is solar-powered!

The solar photovoltaic system on the roof of the Main Library offsets nearly 55 tons greenhouse emissions or as much as that from 12 passenger cars every year. This is in addition to the prestigious Leadership in Energy and Environmental Design (LEED) Silver Certification the Library has already been awarded. The 67-kilowatt, direct-current system generates over 90,000 kilowatt-hours of electricity every year, enough to power roughly 20 typical Alameda households, or up to one quarter of the Library’s annual energy use. 

Typically, solar photovoltaic systems perform best in the summer, offsetting lower winter output, to arrive at the annual expected output.  System performance is affected by a number of factors, most notably sun intensity and ambient temperature. The modules on the Library’s roof are oriented as close to south as possible for best performance and are tilted to maximize summer production.

Thanks to the American Recovery and Reinvestment Act...

Alameda, like many cities, was awarded funds for this project under the American Recovery and Reinvestment Act of 2009. These funds were administered by the US Department of Energy.  ARRA 2009 funds provided $414,000 to the project, creating local jobs and investing in community services with long-term benefits.

...and Alameda Municipal Power

Alameda Municipal Power provided $150,000 toward the project, through its Solar Rebate Program. AMP’s support of solar initiatives results in cleaner power, a reduction in costs to the City, and lower energy costs for its customers.

Sun Light & Power

The Alameda project marks the fourth public library in California where solar integrator Sun Light & Power has installed or is installing solar modules to reduce operating costs and greenhouse gas emissions, provide community leadership and education, and meet new government energy regulations.
