The performance of photovoltaic (PV) modules is critically influenced by environmental factors, with soiling standing out as a significant challenge. This study investigates the impact of soiling, particularly the presence of microorganisms, on the efficiency of PV modules installed near wine production sites, especially during the grape harvest season. Through a detailed case study analysis of a solar power plant in eastern France, this research quantifies the performance degradation caused by biofilm formation and organic residues from wine production activities. Our findings reveal that the accumulation of these contaminants leads to a measurable decrease in energy yield, highlighting the necessity for regular cleaning and maintenance protocols. By exploring the specific types of contaminants and their seasonal variations, this paper provides actionable recommendations for mitigating soiling effects and optimizing the performance of solar PV installations in vineyard regions.
