Abstract:   (2228 Views)

For decreasing the amount of air pollution and green gas emission and saving fossil fuels resource, one of the ways is extending renewable energy utilization. Hence, this yields to growth and development of Photovoltaic systems. Nowadays due to increasing electrical energy requirements and ability to privately providing required energy, the use of solar energy and its electrical power creativity by means of PV systems expanded. In this study an electricity network independent system designed to provide electricity for a house around Karaj at a certain season of the year. The energy demand for this house is 4320 Watt-hours. For providing this amount of energy, 830 watt photovoltaic array, a 1500-watt inverter, a charge controller with a capacity of 40 amp and 24 volt battery with 600 amp hour capacity is needed. The cost needed for this project estimated about 103700000 Rials. PVsyst software used to calculate system losses and finally environmental impact of system compared with conventional systems.
