The San Xavier District of the Tohono O’odham Nation (District) developed grid-tied solar photovoltaic (PV) systems for two tribal buildings: the San Xavier District Administration Building and Education Center. For the Administration Building, an approximately 182-kilowatt (kW) solar PV system is projected to produce roughly 310,000 kilowatt-hours (kWh) per year and displace about 80% of the energy use of the building. For the Education Center, an approximately 73.5-kw system is projected to produce roughly 130,000 kWh per year and displace about 95% of the building’s energy use. The anticipated 25-year cost savings from the combined 255-kW systems are estimated to be approximately $1,750,000 and $820,000 for the Administration Building and the Education Center, respectively.
