Microgrid modular design for tribal healthcare facilities: Kayenta Health Center PV system case study

This paper describes an experimental process and detailed information related to an 100KW PV system case study at the Kayenta Health Center, which is located in the Navajo Nation. Information about the solar irradiance on site, the PV system performance, the power quality at the facility, and observation of the related equipment is gathered. Experimental data validate the theoretical data available for the zone, the facility, the systems and the equipment. Detailed study of existing PV system at the Navajo nation combined with modeling and simulation will discover additional information, tools, process and methodology for the future implementation of the microgrid in other tribal health care facilities. Observation and results demonstrate that the actual implementation of the microgrid at Kayenta Health Center enhance the power quality, result in optimum power system design, produce energy savings and reduce environmental pollution.
