Investigating the influence of solar irradiance variability on the output power of photovoltaic (PV) systems in Akure, Nigeria

Abstract

This research investigates the influence of solar irradiance variability on the output power of photovoltaic (PV) systems in Akure. Given the region's high solar energy potential, understanding how fluctuations in solar irradiance affect PV performance is critical for optimizing solar energy systems. The study involves comprehensive data collection on temperature, solar irradiance, and PV output power, followed by a detailed statistical analysis to quantify the relationship between these variables. Findings reveal a strong positive correlation between solar irradiance and PV output power, indicating that higher irradiance levels significantly enhance power output. The research also highlights the mitigating effect of high irradiance on temperature-induced efficiency losses. Practical implications include recommendations for optimal panel positioning, regular maintenance, and the use of advanced technologies to maximize irradiance exposure and improve system performance. Further research is suggested to explore regional and seasonal variations in irradiance across Nigeria. This study underscores the importance of leveraging Nigeria’s solar potential to enhance PV system efficiency and reliability, contributing to the country's sustainable energy goals.
