Executive Summary Federal agencies, such as the Department of Defense and Department of Homeland Security, as well as numerous private entities are actively pursuing the installation of solar technologies to help reduce fossil fuel energy use and associated emissions, meet sustainability goals, and create more robust or reliable operations. One potential approach identified for siting solar technologies is the installation of solar energy technologies at airports and airfields, which present a significant opportunity for hosting solar technologies due to large amounts of open land. In particular, solar photovoltaics (PV) have a low profile and the potential to have low to no impact on flight operations. This report focuses largely on the Federal Aviation Administration’s (FAA’s) policies toward siting solar technologies at airports. The FAA’s policies cover fixed-axis, flat-plate solar technologies, including solar PV and solar thermal hot water systems. These policies apply to federally obligated airports. Private airports and land adjacent to airports are not covered under these policies, though the FAA encourages stakeholders of such lands who are interested in siting solar systems on those lands follow the FAA’s policies. The FAA’s policies outline how an airport sponsor can gain approval from FAA to amend an airport layout plan to add a solar system. The FAA also offers design resources to help to minimize glint and glare impacts. With proper advanced planning and siting considerations, solar technologies can successfully be installed at airports with minimal or no impacts. This paper concludes with examples of solar installations at airports and highlights a case study where successful systems were installed at the Denver International Airport in Denver, Colorado. v This report is available at no cost from the National Renewable Energy Laboratory (NREL) at www.nrel.gov/publications.
