Design and Simulation of Small Power Stand Alone Solar Photovoltaic Energy System for Residential unit

Abstract: The aim of this study is to design a solar off-grid PV system to supply the required electricity for a residential unit. The solar PV system is simulated with the case of maximum solar radiation on a sunny day. The results show that the average daily load requirement of the selected residential unit is 36 kWh/day. This load requirement can be met by using an array of 44 solar panels. During the day time, the PV system supplies the desired 12.4 kWh of energy. During the night time, a battery storage system of 23.6 kWh (48V, 350 Ah) is used to meet the night load. Keywords: Solar PV panel, stand alone system (Off-Grid), MPPT Controller, Isolated Places .
