Abstract

Three-dimensional computational fluid dynamics (CFD) simulations were performed on parallel-arranged vertical bifacial PV panel structures to investigate wind pressure distributions and wind load characteristics according to lateral panel position and row arrangement. The outermost panel exhibited a maximum local negative pressure of -1252 Pa on the rear surface. However, the intermediate panel produced the largest total wind load, reaching 10,198 N, approximately 8% higher than that of the outermost panel, due to a wider distribution of rear-surface negative pressure. In contrast, the locally high suction on the outermost panel was confined to a limited area. Wind loads on downstream panels were significantly smaller, ranging from -501 to 414 N based on mean pressure, indicating a negligible influence on structural design. These results confirm the necessity of distinguishing between upstream and downstream rows in wind load evaluation and demonstrate the similarity of mean wind loads within the upstream row.
