Photovoltaic bracket vibrates in the wind

Does wind-induced vibration affect flexible PV supports?

Discussion 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.

Does wind load affect flexible photovoltaic support structure?

In this paper, we mainly consider the parametric analysis of the disturbance of the flexible photovoltaic (PV) support structure under two kinds of wind loads, namely, mean wind load and fluctuating… Photovoltaic (PV) system is an essential part in renewable energy development, which exhibits huge market demand.

Can a PV building integration technology reduce wind-induced vibration?

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. PV building integration (Figure 18) is a technology that integrates solar power generation products into buildings.

Do fixed PV supports have a wind-induced response?

While there is substantial research on the wind-induced response of fixed PV supports, encompassing rooftop and ground-mounted systems , , , .Numerical CFD simulations and experimental research have been conducted by several researchers , , , to investigate the wind field and wind-induced response of PV supports system.

Does wind vibration affect photovoltaic structural design?

Currently, the wind vibration coefficient commonly considered in traditional photovoltaic structural design has not been fully taking the factor into account, which may lead to safety hazards or design defects in such designs.

Where do wind-induced vibration responses occur in flexible PV arrays?

The tables indicate that the maximum wind-induced vibration responses in the flexible PV array group occur at the mid-span under both wind suction and wind-pressure conditions, with the responses gradually decreasing towards the edges under wind-pressure conditions. Table 7.
