(1) Background: As environmental issues gain more attention, switching from conventional energy has become a recurring theme. This has led to the widespread development of photovoltaic (PV) power generation systems. PV supports, which support PV power generation systems, are extremely vulnerable to wind loads.
China generated 241.4 billion kWh of PV power in 2021 and 325.9 billion kWh in 2022, indicating an annual increase of 35%. However, wind damage to PV supports occurs from time to time, and the most significant load when designing PV supports is the wind load.
Flexible photovoltaic (PV) support is a flexible support system composed of PV panels, flexible prestressed cables and steel rods, and so on. Compared with fixed PV support, it has the advantages of high headroom, large span, low cost and flexible site, etc.
Making full use of the previous research results, the following are the main wind load issues associated with the three types of PV supports: (1) the factors affecting the wind loads of PV supports—the main factors are shown in Figure 2; (2) the wind-induced vibration of PV supports; (3) the value and calculation of the wind load of a PV support.
(3) Conclusions: According to the particularity of the PV support structure, the impact of different factors on the PV support''s wind load should be comprehensively considered, and a more
