Design and Analysis of Off Grid Solar System for DC Load of a House in Pakistan

Abstract

Solar energy is the cleanest and most developed form of renewable energy. In order to be completely independent of the grid source we need to have off grid solar system. In this paper we have designed an off grid DC solar system using homer pro. We have used 8 batteries, 36 PV modules to make a DC system that would be sufficient enough to provide the requirement of home with load of 7.81 kWh/day. Steady state as well as dynamic system modelling is included in the paper. Presented results will help further in the design of small scaled off grid solar systems. Designed off-grid system will be independent of the national grid for the power supply and will lead to indigenousness.
