6 FAQs about [Photovoltaic support wind resistance reinforcement measures]

How wind induced vibration response of flexible PV support structure?

Aeroelastic model wind tunnel tests The wind-induced vibration response of flexible PV support structure under different cases was studied by using aeroelastic model for wind tunnel test, including different tilt angles of PV modules, different initial force of cables, and different wind speeds.

What is the wind vibration coefficient of flexible PV support structure?

The wind vibration coefficients in different zones under the wind pressure or wind suction are mostly between 2.0 and 2.15. Compared with the experimental results, the current Chinese national standards are relatively conservative in the equivalent static wind loads of flexible PV support structure. 1. Introduction

Why is wind resistance important in PV power generation systems?

Therefore, wind resistance is essential for a safe, durable, and sustainable PV power generation system. There are three modes of support in PV power generation systems: fixed , flexible , and floating [4, 5]. Fixed PV supports are structures with the same rear position and angle.

What are the reinforcement strategies for flexible PV support structures?

This study proposes and evaluates several reinforcement strategies for flexible PV support structures. The baseline, unreinforced flexible PV support structure is designated as F. The first reinforcement strategy involves increasing the diameter of the prestressed cables to 17.8 mm and 21.6 mm, respectively.

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.

Are flexible PV support structures prone to vibrations under cross winds?

For aeroelastic model tests, it can be observed that the flexible PV support structure is prone to large vibrations under cross winds. The mean vertical displacement of the flexible PV support structure increases with the wind speed and tilt angle of the PV modules.
