SolarResilient: A New Tool for Resilient Solar+Storage Design

Thursday, August 3, 2017 @ 2:00 PM - 3:00 PM

Through a U.S. Department of Energy SunShot Initiative grant, the City and County of San Francisco has developed a publicly available online tool for sizing solar PV and battery storage systems designed to deliver onsite power during an extended grid outage. is a first-of-its-kind tool that enables building and energy managers, architects, and sustainability and energy professionals to optimize solar and battery storage sizing to serve as a clean, reliable source of backup power for critical loads.

The tool allows building owners and city departments to develop preliminary solar and storage equipment sizing estimates before embarking on more detailed studies. can also be used on a portfolio of buildings so that optimum scenarios can be incorporated into a city or county’s energy resilience strategy. The tool is freely available for public use and allows for system design in any location across the United States.

In this webinar, Jessica Tse (San Francisco Department of the Environment) and Russell Carr (Arup) introduced the project and provided a live demonstration of the tool’s capabilities.
