Performance Evaluation of Hybrid Solar Photovoltaic/Biogas Systems Connected to the Grid: Case Study of a Rural Community in Argentina

This study models and evaluates a hybrid energy system for the Pujato Norte community, integrating photovoltaic solar, a biogas generator, and grid connection. Using HOMER Pro software, the project assessed economic feasibility, operational aspects, and maintenance costs over a 25-year projection, targeting a minimum 50% renewable energy contribution. Results indicate an optimal configuration comprising a 501 kW photovoltaic plant and a 50 kW biomass generator, capable of meeting the average daily load of 4,109 kWh. While the estimated initial investment is USD 997,029 and the resulting energy cost of USD 0.1738/kWh exceeds current grid rates, the system delivers a significant environmental benefit: a 41% reduction in carbon dioxide emissions, equivalent to 297,554.86 kg CO annually. This substantial decrease underscores the hybrid system's potential to provide a more sustainable, long-term energy alternative by mitigating the environmental impact of local power generation.
