“…Designs for a PV system often use wind loading standards, such as the American Society Civil Engineers (ASCE 7) [7,20], in order to calculate wind loads. However, wind loads can be larger than the ASCE 7 standard [21]. For PV panels floating directly on the surface of water, Trapani et al [3] showed that the system is subject to salt water corrosion and to the dynamics of tides, wind, and waves.…”

A solar photovoltaic system consists of tilted panels and is prone to extreme wind loads during hurricanes or typhoons. To ensure the proper functioning of the system, it is important to determine its aerodynamic characteristics. Offshore photovoltaic (PV) systems have been developed in recent years. Wind loads are associated with wind, wave climates, and tidal regimes. In this study, the orientation of a single panel is adjusted to different angles of tilt (10°–80°) and angles of incidence for wind (0°–180°) that are pertinent to offshore PV panels. The critical wind loads on a tilted panel are observed at lower angles of incidence for the wind, when the angle of tilt for the panel is greater than 30°.

Photovoltaic generation systems can automatically track the angle of sunlight. The system consists of four photovoltaic (PV) panels which can adjust pitch angle and azimuth angle according to the sunlight. The variation of the wind coefficient and wind load characteristics of the PV panels with the pitch angle and azimuth angle is obtained through the wind tunnel simulation based on FLUENT to determine the flow characteristics around the PV panels.

“…These extreme wind weather made solar panels are unable to maintain normal conditions [3]. PV panels in landscape format placed on commercial buildings or flat ground are typically arranged in arrays supported by elevated steel or aluminum frames at an angle between twenty and forty degrees [4]. This tilt allows photovoltaic panels to receive more radiation, but also makes photovoltaic panels more damaged in extreme wind conditions [5] [6].…”

The dual-carbon target has made solar photovoltaic panels widely used. But the normal operation of photovoltaic panels under extreme weather conditions is still an important issue to be solved. For large-area photovoltaic arrays, the effect of photovoltaic panels under extreme wind weather, such as typhoon, is becoming more obvious. To solve the above dilemma, this paper established the numerical simulation model of photovoltaic panels under turbulence field, and studied the displacement of the solar panels when the wind speed is over 25m/s. The results have shown that when the flow rate is 25m/s, the maximum relative pressure of the solar panel is about 70Pa, which appears on the upper right and left of the solar panel. The maximum displacement caused by the wind also appears on the same point of the solar panel, which even reached 1mm in solid surface. After this the economic analysis has also been done for PV operation and maintenance. The machine replacement rate data dropped from 5.6% to 1.7% after added the reinforced facilities. The LCOE for PV also reduced. These results can provide an important reference for the planning of solar panels and the effective operation under extreme weather conditions like typhoon in the future.
