Design and Performance Evaluation of Wind-Solar PV Energy System for Kola Village at Birnin Kebbi, Nigeria

Abstract

This paper presents the results from a designed and simulated wind - solar PV hybrid energy system for residential power requirements of Kola village in Birnin Kebbi, Nigeria. The components designed comprised of wind energy conversion and solar photovoltaic (PV) subsystems, storage batteries and charge controller. 20kW PV array and 10kW wind turbines were integrated in a hybrid arrangement with a battery bank of 12V/200Ah and an average daily energy consumption of 4100 Wh. The Hybrid Optimization Model for Electric Renewables (HOMER) software as well as wind and solar resources data from the Nigeria Meteorological Agency (NIMET) were utilized for the analysis. The total generated power (141,162kWh/yr) meets the load requirement of the location. The wind energy resource contributed 75.25% electrical energy to the system while the solar PV resource (24.25%). The simulated most cost effective system configuration was found to have a total Net Present Cost (NPC) of $236,415 and a levelised Cost of Energy (COEL) of 0.413 $/kWh.
