Does wind load affect solar panels?

Choi et al. confirmed the effect of wind load on the solar panel array of a floating PV system through an indoor model experiment. Experiments have shown that the first and last rows of panels have the highest drag and lift coefficients because they are the first to encounter the wind [ 6 ].

How does wind load affect PV panel support?

2. Influencing Factors of Wind Load of PV Panel Support 2.1. Panel Inclination Angle The angle β between the PV panel and the horizontal plane is called the panel inclination (Figure 3). Because of the PV panel’s varying inclination angle, a PV power generation system’s wind load varies, impacting the system’s power generation efficiency. Figure 3.

How does wind load affect PV power generation?

A wind load accelerates the cooling of PV panels, thereby reducing the cell’s temperature and increasing the power generation efficiency for PV power generation. However, the PV panel generates wind-induced vibration due to the wind load, which can damage the system (Figure 12).

How does wind pressure affect PV modules?

Wind pressure distribution on PV modules.
