When wind interacts with a solar panel, it generates pressure both on the windward side, where the wind hits, and suction on the leeward side. This dynamic creates a complex set of forces that can affect the panel's stability and overall performance, particularly in high-wind. . The wind load characteristics on both sides of the photovoltaic panels were obtained, and the vortex structure characteristics were analyzed using the Q criterion. The tilt angles are 15° and 30° and the wind incidence is at an angle of 0–180° (in increments of 15°). With the rapid growth of solar installations, ASCE 7-16 introduced dedicated provisions for solar panels, and ASCE 7-22 expanded these. . he solar photovoltaic panel structure. In this article, we will be discussing how to calculate the snow and wind loads on ground-mounted solar panels using ASCE 7-16.
