Abstract: In this work, we designed, built and tested a mini station for measuring solar irradiation, temperature and air humidity at the Higher Institute of Technology (IST), Mamou. For this purpose, we designed a device far from any shading, consisting a 2m in three-piece of mast topped by a squaresh tube bar to which the pyranometer, temperature and humidity sensor are attached, a metal box serving as a shelter for the irradiation and temperature dataloggers, the photovoltaic system equipment and a 20Wp solar panel to supply the system with energy. A grounding device protected the entire system. After parameterization and direct measurements during the test period from August 12 to 20, 2024, seven hundred and forty-two (742) lines of data were recorded and plotted for analysis. The following results were obtained: A coverage rate of 100% and around 75h of sunshine. However, the days 13, 14, 16, 19 and 20 were very sunny, with a maximum value of 1224W/m², a minimum of 1W/m² and an average of 142W/m². Minimum and maximum temperatures were 18°C and 31.7°C respectively, with an average of 11.17°C. For humidity, the maximum (99.9%) was recorded almost every morning and evening during the same period, the minimum 7.4% (August 15 at 3:48 P.M) with an average of 95.34%.

Abstract: Nigeria, as a developing country, faces persistent challenges with epileptic power supply, particularly in rural communities. This study investigates the technical feasibility and performance of integrating solar energy into Nigeria’s national grid to enhance electricity supply, using Umuezerokam community in Imo State as a case study. The objective is to assess the solar energy potential and system performance of a 750 kW grid-tied photovoltaic (PV) system through advanced simulation using the Solargis-pvPlanner tool. Key performance indicators, including Global Tilted Irradiation (GTI) averaging 140–160 kWh/m²/month, specific PV output ranging from 99.2 to 125 kWh/kWp, and a Performance Ratio (PR) averaging 80.7%, were analyzed based on site-specific solar and meteorological data. The results reveal that Umuezerokam experiences an annual average solar irradiance of approximately 4.6 kWh/m²/day, making it highly suitable for solar electricity generation. Simulation outcomes show that the proposed solar PV system can produce about 1.019 GWh annually, meeting the estimated energy needs of over 300 households and improving daily electricity supply from an average of 5–6 hours to about 11 hours. The study concludes that solar energy integration into the national grid is technically feasible and capable of significantly enhancing electricity supply in rural Nigeria. Furthermore, adopting such solutions would contribute to Nigeria's sustainable development goals by promoting the use of renewable energy. These findings provide critical insights for policymakers, investors, and local authorities seeking to address energy poverty through clean energy technologies.
