Technical Specifications for Photovoltaic Flexible Support

What is a flexible PV support structure?

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. These configurations are named F1-1 and F1-2 for ease of comparison.

Do flexible PV support structures have resonant frequencies?

Modal analysis reveals that the flexible PV support structures do not experience resonant frequencies that could amplify oscillations. The analysis also provides insights into the mode shapes of these structures. An analysis of the wind-induced vibration responses of the flexible PV support structures was conducted.

Why do we need flexible PV support systems?

The traditional rigid PV support systems face several issues and limitations, such as the requirement for large land areas, which constrain their deployment and development, especially in eastern regions . In response to these challenges, flexible PV support systems have rapidly developed.

What are the components of a flexible PV system?

The essential components of flexible PV systems include the tracker torque tube, a drive mechanism, and PV modules. They have greater efficiency than stationary arrays of PV modules because the system can adjust the angle of the PV modules to the sun.

What is a PV support structure?

Support structures are the foundation of PV modules and directly affect the operational safety and construction investment of PV power plants. A good PV support structure can significantly reduce construction and maintenance costs. In addition, PV modules are susceptible to turbulence and wind gusts, so wind load is the control load of PV modules.

What is flexible PV technology?

Flexible PV technologies require highly functional materials, compatible processes, and suitable equipment. The highlighting features of flexible PV devices are their low weight and foldability. Appropriate materials as substrates are essential to realize flexible PV devices with stable and excellent performance.
