6 FAQs about [Calculation rules for wind loads in photovoltaic power generation]

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 is wind load calculated in a PV structure?

The loads applied to the design of PV structures were described earlier. In the structural design of the PV structure, the wind load is assumed to be applied in the horizontal direction, and the basic assumption is that it is calculated by considering the projected area of the structure [ 11, 12 ].

Does wind load affect a solar PV system?

Using shear stress transport (SST) \ (k {-}\omega\) model, CFD predicted a PV system of a single ground-mounted type for wind load on the solar panels. Effects of wind on stand-alone photovoltaic (PV) systems installed on the ground under various wind directions were investigated. (Mohammad and Horia 2014).

Do ground clearance and row spacing affect PV wind loads?

By summarizing the existing results, it can be found that research on the effect of ground clearance and row spacing on PV wind loads is still very lacking, and the existing research only focuses on a single row of PV modules at a specific angle without considering the interference effect of PV arrays.

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

How does wind load affect PV modules?

This means that the wind load on the PV modules decreases rapidly after the first row of PV modules is flown, which is characteristic of a fluid flowing over a certain obstacle.
