This report documents the specification, design, installation, and acceptance of a 5-kilowatt-peak, grid-connected, photovoltaic power system for the Holman Guest House at Fort Huachuca, AZ. This system, designed and installed at a cost of 112,000, was funded by the Department of Energys Federal Photovoltaic Utilization Program. The system operates in parallel with the local utility grid without battery storage. The photovoltaic PV array, consisting of 196 roof-mounted panels, generates direct current at about 210 V. The array output is converted to alternating current by a three-phase, line-commutated inverter developed specifically for the application. The inverter output, estimated at about 11,000 kWh per year, meets a portion of the Guest Houses electrical demands. Tests performed at the time of the systems acceptance have demonstrated its ability to deliver the rated power output. The U.S. Army Construction Engineering Research Laboratory is now conducting a 1-year evaluation to determine the systemss long-term performance and to learn more about the feasibility of applying grid-connected PV systems to fixed military facilities.
