Abstract

Grid-connected photovoltaic (PV) systems offer a promising solution for enhancing electricity supply
in rural communities with poor or unreliable grid infrastructure. This study presents a techno-economic
assessment of a grid-connected solar PV system for Asarara community in Kebbi State, Nigeria. The
community load demand was estimated based on residential and commercial consumption patterns, and
solar resource data were obtained from standard meteorological databases. The PV system was then
modeled, simulated, and optimized using HOMER Pro software by evaluating different system
configurations under technical and economic constraints, while performance validation was conducted
using PVsyst through energy yield and system efficiency analysis. Simulation results indicate an annual
PV generation of 865,224 kWh with a net present cost (NPC) of ₦109 million and a levelized cost of
energy (LCOE) of ₦10.02/kWh. The system achieved an internal rate of return (IRR) of 19.3%,
confirming its economic viability. PVsyst validation shows consistent energy yield and high solar
utilization efficiency. The results demonstrate that grid-connected PV systems can significantly improve
electricity reliability, reduce dependence on fossil fuel generation, and provide cost-effective energy for
rural communities in Nigeria.
