The photovoltaic bracket was blown by the wind

The wind load is a vital load affecting PV supports, and the harm caused by wind-induced vibration due to wind loads is enormous. Aiming at the wind-induced vibration of flexible PV supports, a PV building integration technology [86, 87] was proposed to reduce the harm caused by wind vibration.

The wind load on the photovoltaic panel array is sensitive to wind speed, wind direction, turbulence intensity, and the parameters of the solar photovoltaic panel structure. Many researchers have carried out experimental and numerical simulation analyses on the wind load of photovoltaic panel arrays. Table 1.

Abstract: In order to study the mechanica properties of the fixed photovoltaic bracket and its failure under wind load, the full-scale photovoltaic bracket specimen was designed and the destructive test was carried out by means of static loading.

Boundary layer wind tunnel tests were performed to determine wind loads over ground mounted photovoltaic modules, considering two situations: stand-alone and forming an array of panels. Several wind directions and inclinations of the photovoltaic modules were taken into account in order to detect possible wind load combinations that may lead to .

Wind impinging on the first row of solar panels resulted in a separated flow and recirculating zone behind the panels. As the wind passed along the solar panel array, the wind speed gradually decreased because of the sheltering effect of the first row.

6 FAQs about [The photovoltaic bracket was blown by the wind]

How does wind load affect photovoltaic panels?

How does wind pressure affect a front-row photovoltaic panel?

Pressure distribution along the solar panel profile line. In addition to SP1 being subjected to the main wind load, the wind pressure attenuation of the rest of array a is obvious. Hence, the structure needs to focus on strengthening the structural strength of the front-row photovoltaic panels.

Does a guide plate affect the wind load on a solar panel?

However, they analyzed the effects of the guide plate in the single solar collector. Bitsuamlak et al. numerically analyzed the wind load on a solar panel array and observed the maximum wind load at an inlet angle of 180°. Thus, they proved that wind load on the 180° should be considered more importantly than other flow directions.

Why is wind load important for a Floating photovoltaic system?

The wind load is especially important for floating photovoltaic systems. Fig. 2, a floating photovoltaic system is above the sea or a lake. A floating body supports the solar panels by the buoyancy force, which is balanced with the weights of the solar panel and itself.

How does a photovoltaic array develop along the wind direction?

However, the flow of other arrays developed along the wind direction when the wind passed the SP2 to SP6 (Figs. 9 b–f). For array b, a fluctuating region similar to regular waves is formed as they flow through SP3, which is closely related to the equidistant staggered installation form of photovoltaic panels.

Can solar photovoltaic arrays balance wind load and buoyancy?

And a solar photovoltaic array layout that can balance wind load and buoyancy is proposed to achieve the purpose of preventing the floating structure from sinking or overturning. 3.1. Flow characteristics Fig. 9 shows the wind speed distributions at monitoring surface 1 for different layouts.
