Abstract: 

This thesis describes the optimal operation and economic analysis of rural electrification of Atouf village by electric network, diesel generator and photovoltaic system, and also the design and testing of an 11.7 kWp PV system and summarizes its performance results after the first 6 months of operation. This system functions as a stand-alone power system used to supply electricity for Atouf village. The system is comprised of the following components. An array consist of PV modules produced from polycrystalline solar cell of 130W, making up a total peak power of 11.7 kW. In addition, there is one inverter of 7.2 kW, and an energy storage system of 120 kWh. After the first 6 months of system operation from December 2007 to May 2008, it was found that all the components and the overall system had worked efficiently. In total, the system had generated during this period about 7596 kWh, average solar radiation in this period about 4.67kWh/m2- day, daily input solar energy of the total system surface was 390.5kWh, and the average electricity production per day was 46.11kW. From the economical view point, photovoltaic energy system differ from conventional energy systems in that they have high initial cost and low operating costs. This study shows that the unit cost of the PV system is 2.69 NIS/kWh which is less than that of the diesel generator systems in Atouf village.
