This paper investigates energy losses in large-scale photovoltaic (PV) generators caused by wind patterns. Contrary to smaller-scale observations where wind-enhanced cooling improved efficiency, this study shows that increased wind speed in a real-world setting can lead to notable energy losses. These losses are reflected in mismatch losses (MML) directly linked to variations in module operating voltage due to uneven temperature distribution across the PV panels. Temperature differences result from variable heat transfer influenced by wind incidence, affecting module operating temperatures and voltages, ultimately increasing MML by up to 0.28%. The findings highlight the importance of considering wind patterns in long-term energy estimations and PV plant lifespan.
