چکیده

In the quest for sustainable energy solutions, this study analyses the hybrid solar photovoltaic (PV)-diesel generator system’s feasibility for reliable electricity supply to a mini-mart in Ajase-Ipo, Nigeria. Utilizing HOMER software, the system was modelled and optimized with a focus on both technical and economic factors. The optimal configuration comprises a 10.2 kW solar PV system, 8 batteries, a 6-kW converter, and a 10-kW diesel generator, meeting the annual energy demand of 29,200 kWh. The system’s technical performance is highlighted by a capacity utilization factor of 17.9% and a performance ratio of 82.16%, demonstrating the efficiency of the solar PV system. However, heavy reliance on diesel fuel, with an annual consumption of 5,632 litres, leads to a high levelized cost of energy (LCOE) of 306.16 per kWh. This underscores the need for strategies to reduce diesel dependency and improve long-term economic viability through improved solar capture and optimized battery storage. The system also demonstrates significant environmental benefits, with CO2 emissions reduced by 8,614 kg annually, alongside reductions in other harmful pollutants such as CO, SO2, and NOx. These findings reinforce the potential of renewable energy to provide a more sustainable, cost-effective, and environmentally friendly solution for electricity generation in similar contexts.
