Techno-Economic Analysis of Photo-voltaic and Diesel Hybrid System For Off-Grid Filling Station Operation in Nigeria

The development in Photo-voltaic technology globally is rapidly increasing as PV cell is a major component in renewable energy system. This paper focuses on the generation and supply of electricity using hybrid photovoltaic diesel for filling station operation. This study is geared towards covering the existing gap in relation to failure of public electricity supply by the grid to meet the energy demands for the operation of a filling station. This paper presents a techno-economic analysis in deploying a PV-Diesel hybrid system for filling station operation in Nigeria. The model filling station is located in the Ikeja metropolis of Lagos State Nigeria, (Longitude 3.3364, Latitude 6.5944 and Altitude 71M). The results obtained shows the PV cell of the energy system is sized at 25KWp, a diesel generator rated at 30KW, and a hybrid inverter rated at 20KW. The energy system also has a battery storage system of 1483AH derived from 32units of 180AH lithium-ion battery, connected in 8 strings of 4 in each battery pack. The total energy demand for the annual operation of the filling station is 17002 KWh / yr and the excess is stored up in the battery storage system. The Levelised cost of energy (LCOE) is 0.37USD/KWh.
