Design, Simulation and Economic Analysis of Solar Photovoltaic Systems for Households and Businesses in Mogadishu

The number of people in Mogadishu who use electricity has significantly increased during the past few years. most of Mogadishu’s energy comes from fossil fuels which is nonrenewable energy sources. The use of solar energy to power our day-to-day life has great untapped potential. According to researchers, The amount of sunlight that reaches the surface of the Earth in an hour and a half is enough to meet the world's yearly energy requirements. The purpose of this study is to design, simulate and evaluate solar photovoltaic system for residential and business in Mogadishu using PVsyst software and the load estimation for the two cases based on the average primary load profile of each category. Case one, for the residential household we designed an off-grid PV system that generates 3163 kwh/year. and its performance is 71.8% which is good, Also, we compared the costs of Off-Grid and the utility grid for 15 years, the result shows that Off-Grid has a cost savings of 5263 dollars. Case two, for the business we designed (JUST) compos 3 a Grid-Connected PV system that generates 104Mw.h/year, and its performance was 79.6% which is good. Also, we compared the costs of Grid-Connected and the Utility Grid for 15years and the result shows that the Grid-Connected has a saving cost of 656593 dollars.
