Energy access and reliability are high priorities at the U.S. Army bases in Afghanistan. Using photovoltaic (PV) arrays can help diversify the systems that supply energy to a given area increasing energy safety, security, reliability and sustainability—and thus improving energy surety. PV systems, which convert incoming solar radiation into usable electric power, may be a wise choice for bases in the Middle East because the solar resource is relatively constant and abundant. Solar resource refers to the amount of solar radiation a given location on earth’s surface receives. The solar resource for two locations were investigated in this study using site-specific weather data combined with satellite generated data produced by NASA’s Prediction of Worldwide Energy Resource project. This research compares the cost effectiveness and potential energy production of a PV system for 1,500 sq. ft housing units at two locations in Afghanistan with varying weather conditions.
