ABSTRACT
This study details the design and comprehensive economic analysis of a standalone photovoltaic inverter system tailored for selected load centres within the Faculty of Engineering, University of Benin. It addresses the necessity for a cleaner and cheaper power source amid rising costs, proposing a resilient renewable energy alternative. Methodology began with a load survey to quantify consumption patterns and peak demand. Components were sized using mathematical equations. Optimization was conducted using the Hybrid Optimization of Multiple Energy Resources Pro software. Lifecycle cost was compared against the utility grid energy cost. Simulation and economic assessment confirmed the viability and financial advantage of the designed system. The levelized cost of energy was calculated to be N143.47 per kilowatt-hour, demonstrating significant cost benefit when compared to utility grid supply rate of N209.5 per kilowatt-hour. This result shows that the photovoltaic solution is cheaper and more sustainable over the 25-year project lifetime. With a payback period of 13.4 years, the study concludes the proposed system represents a financially stable and economically competitive investment.
