Off Grid Photovoltaic System Design Considering Reliability and Cost Indicators (Case Study: Kermanshah, Iran)

Abstract

Daily sunshine duration is one of the factors influencing the size of solar panels in a photovoltaic system. When the system is designed and the number of system components is calculated, the average of sunshine hours is usually used. However, sunshine hours are less than average and we are faced to shortage and surplus of electricity in the winter and summer, respectively. In this paper due to sunshine hours in 12 months and their average, 13 plans are provided for the photovoltaic system design. Because of a reliability indicator of access to electricity and economic indicators, we choose a suitable scheme.
