This web tool helps building owners evaluate the economics of grid-connected solar photovoltaics (PV) and battery storage at commercial sites. It identifies the optimal PV system size and battery dispatch strategy to minimize the life cycle cost of energy at a specific site. The web tool also estimates the amount of time a PV and battery system can sustain the site's critical load during a grid outage. The REopt Lite web tool was developed with funding from the U.S. Department of Energys (DOEs) Federal Energy Management Program (FEMP), the DOE Solar Energy Technologies Office, and the nonprofit Clean Energy Groups Resilient Power Project, with support from The Kresge Foundation.
