Civil engineering photovoltaic power generation wind resistance

How is wind load evaluated in a PV power plant?

Wind load is evaluated as relatively low because only the projected area in the horizontal direction is considered in the design standard. Therefore, the wind load applied to all arrays of the PV power plant was evaluated through the CFD analysis.

How does wind pressure affect PV modules?

Wind pressure distribution on PV modules. When the wind is incident in the forward direction of the PV module, regardless of the wind speed, the pressure load on the PV module is the largest in the second row and decreases sharply from the third array, then increases gradually after passing through a certain array, and then decreases.

What is the wind load distribution of PV modules?

Based on the numerical analysis, the wind load distribution of PV modules can be characterized with respect to the inlet angle and wind speed. The numerical results show that the wind loads in the central arrays are dominant. 1. Introduction

Does wind load affect a floating PV system?

The load distribution caused by the wind load in the floating PV system was assessed using possible parametric studies with design parameters including wind speed, wind direction, and installation angle of PV modules. In this study, the design load was confirmed to install a floating PV power generation structure in salt-reclaimed land.

Why is a floating PV power plant more vulnerable to wind?

In addition, the wind pressure generated a large pressure only in the first PV panel and decreased toward the backward direction because the flow was stable. Therefore, it is judged that the floating PV power plant is structurally more vulnerable to the wind acting from the backward direction.

Which structural component is most important in photovoltaic module design?

For the case of the photovoltaic module array, it is observed that the wind loading over the leading panels is decisive for the design. According to the numerical results, the central support device is the most critical structural component. 1. Introduction Flow over inclined bluff bodies are of particular interest in wind engineering.
