Abstract: In the context of the energy transition and Senegal’s objective to increase the share of renewable energy to 20%, this study investigates the reliability of an off-grid photovoltaic (PV) power plant located in the village of Badiari, Sédhiou region, in the south of the country. Over a three-month period (June to August), corresponding to the rainy season, the 5 kWp production system was continuously monitored using an intelligent SMA inverter, enabling minute-by-minute data collection. The analysis reveals a clear mismatch between the system’s generation capacity and the users’ energy demand. The lead-acid batteries (1,000 Ah) undergo recurrent deep discharges, occasionally reaching critical levels (21 % state of charge), significantly shortening their operational lifespan. Simultaneously, the backup generator, intended to mitigate these deep discharges, is seldom activated. Frequent overvoltage events, shutdowns due to extreme temperatures (up to 80 °C at the heat sink), and islanding phenomena highlight both system imbalance and structural vulnerability. Reliability metrics were quantified, with a Mean Time Between Failures (MTBF) of 10,907 minutes and a Mean Time To Repair (MTTR) of 43 minutes in June, compared to 8,671 minutes and 329 minutes, respectively, in August. These values underscore the irregularity of energy supply. The findings emphasize the need to reconsider the sizing and maintenance strategies of rural solar installations. Recommended measures include increasing battery bank capacity (up to 2,500 Ah), introducing power limiters for consumers, and improving the thermal management of the technical room (ventilation, insulation). Implementing these strategies is expected to enhance local energy autonomy and improve the long-term sustainability of solar infrastructures.

Abstract: Monocrystalline and polycrystalline silicon-based modules are commonly used in Burkina Faso, particularly in the city of Koudougou, to generate electricity. However, climatic parameters affect the performance of these modules. It is therefore necessary to conduct a comparative study between polycrystalline and monocrystalline silicon-based photovoltaic solar modules. The objective of this work is therefore to determine the module best suited to the city of Koudougou's climatic context. In this study, climatic parameters such as sunshine and temperature were considered. Thus, based on the mathematical model of a photovoltaic module, a simulation was carried out in the MATLAB/Simulink environment an experimental study of the two types of modules was conducted. The results obtained after the simulations and experiments were compared. Analysis of the results for the two module technologies shows that during the period of the day when the temperature is high, the polycrystalline silicon-based module performs better than the monocrystalline silicon-based module. However, during periods when the temperature is lower, the monocrystalline module performs better than the polycrystalline module. Considering the average daily power output for October 2024, it appears that the monocrystalline silicon-based module performs better than the polycrystalline silicon-based module. In general, monocrystalline modules offer better technical performance than polycrystalline modules in the climate of the city of Koudougou.
