In general, schools make excellent resilient shelters, as they are centrally located, can accommodate many people, and typically have large, flat roofs and open spaces where PV panels can be installed.

SunSmart Emergency Shelters Program

Multiple Locations, Florida

Beginning in 2012, in an effort coordinated by University of Central Florida’s (UCF’s) Florida Solar Energy Center in collaboration with the Florida Office of Energy, Florida’s SunSmart E-Shelter Program has equipped more than 100 public schools with small PV systems and batteries, which are sufficient to keep lights and electrical outlets operating during a grid-disrupting natural disaster.  This enables these schools to serve as self-powered places of refuge for communities across the state, providing emergency shelter for 100-500 people per site.

Schools often make excellent emergency shelters, as they are centrally located and can accommodate many people. Also, schools typically have large, flat roofs and open spaces where PV panels can be installed, in fact many schools across the nation already have solar installed. In the case of the Florida program, the state designated selected schools as hurricane shelters, with interior spaces retrofitted as hardened “enhanced hurricane protection areas.” In order to provide a safe haven during extended power outages, a pre-determined set of critical loads, like lighting and outlets for charging and communications, were designated to be supported by resilient power solar+storage systems.

Schools also make an excellent site for renewable energy generation because of the opportunity to integrate these systems into the curriculum, as is being done in this Florida program. Through the SunSmart E-Shelter Program, more than 350 teachers have received professional development in incorporating the science of solar PV into their classrooms. More than 50,000 students have been introduced to solar PV as a result, using a STEM (science, technology, engineering, and math) curriculum that was also developed through the SunSmart E-Shelters program. Each school was provided with a kit of materials for lab tests and a website to view their school’s solar PV output. The curriculum is designed to teach students how solar PV works, how to prepare for disasters, and the relationship between energy and the environment.

Each shelter is supported by a small solar+storage system – a typical system consists of a 10kW solar PV array, with a 48kW battery – that are relatively inexpensive to deploy: installed costs range from $74,000 to $90,000 per school. Because the program is funded through the American Recovery and Reinvestment Act, which designated stimulus funds to be invested in infrastructure, education, and renewable energy, all components are required to be U.S.-made. The state was able to negotiate a volume discount by using a single installer for the entire state. Schools received the systems at no cost, and program staff calculated that the systems would save each school around $1,500-$1,600 per year in electricity costs.
