How to solve the problem of photovoltaic bracket shaking

How safe are flexible PV brackets under extreme operating conditions?

Safety Analysis under Extreme Operating Conditions For flexible PV brackets, the allowable deflection value adopted in current engineering practice is 1/100 of the span length . To ensure the safety of PV modules under extreme static conditions, a detailed analysis of a series of extreme scenarios will be conducted.

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.

How to reduce wind load of PV support structure?

It is also necessary to reasonably increase the template gap and reduce the ground clearance in order to reduce the wind load of the PV support structure, enhance the wind resistance of the PV support structure, and improve the safety and reliability of the PV support structure. 2.7. Other Factors

What is the vibration avoidance strategy for hydropower?

The vibration avoidance strategy proposed in this study effectively avoids operating in the vibration zone for hydropower units (the vibration rates decrease from 7.6 %, 6.7 %, 6.3 % to 0 under three initial water levels respectively), which is at the cost of increasing the number of units involved in regulation.

Are cable-supported PV panels prone to vibrations when exposed to crosswinds?

The primary findings can be summarized as follows: cable-supported PV panels are susceptible to significant vibrations when exposed to crosswinds; leeward PV panels experience less vibration than windward panels, primarily due to the shielding effect.

What are the main wind load issues associated with PV supports?

Making full use of the previous research results, the following are the main wind load issues associated with the three types of PV supports: (1) the factors affecting the wind loads of PV supports—the main factors are shown in Figure 2; (2) the wind-induced vibration of PV supports; (3) the value and calculation of the wind load of a PV support.
