When the wind speed and direction change, the front and back surfaces of the photovoltaic panels will experience different wind loads. Currently, the wind load characteristics of solar photovoltaic panels under extreme weather conditions have not been systematically uncovered.
Kopp et al. performed a wind tunnel study on roof-mounted solar arrays with two panel inclination angles. Two main mechanisms for the aerodynamic loads were obtained: (1) the panels’ turbulence; (2) pressure equalization. The array created turbulence at high inclination angles, which raised the net wind loads.
Stathopoulos et al (2014) studied wind effect on solar panels mounted on the roofs of 7 m and 16 m high buildings, and it was found that height of building has little effects on wind load of panels.
1. Introduction Roof mounted photovoltaic (PV) panel systems are widely used in modern society. The natural flow of wind effectively reduces the elevated temperature and the direction of wind flow plays a very prominent role in heat evacuation for PV panel systems (Agrawal et al 2021).
Banks et al. investigated the uplift wind loads on the roofs of wide, rectangular, low-rise, flat-roofed buildings using tilted flat PV panels in an atmospheric boundary-layer wind tunnel. The findings showed a significant difference in wind load between the corner vortices and the cases without them.
Radu et al. investigated the steady-state wind load characteristics affecting two rectangular flat panel solar collectors of varying sizes through experiments in boundary-layer wind tunnels. Because of the building’s and the first row of collectors’ sheltering qualities, the wind loads on the solar collectors significantly decreased.

How Rooftop Solar Works: Components, Conversion, and Benefits
Solar panels, also known as photovoltaic cells, are the main components of a rooftop solar system. These panels are responsible for converting sunlight into electricity through the photovoltaic effect. The size of the solar panel determines the amount of electricity it can generate. In an off-grid system, the solar panels are connected to a battery bank to store …
