6 FAQs about [Principle of flexible support for photovoltaic power station]
Why are flexible PV mounting systems important?
Traditional rigid photovoltaic (PV) support structures exhibit several limitations during operational deployment. Therefore, flexible PV mounting systems have been developed. These flexible PV supports, characterized by their heightened sensitivity to wind loading, necessitate a thorough analysis of their static and dynamic responses.
What is a flexible photovoltaic (PV) system?
Author to whom correspondence should be addressed. Photovoltaic (PV) system is an essential part in renewable energy development, which exhibits huge market demand. In comparison with traditional rigid-supported photovoltaic (PV) system, the flexible photovoltaic (PV) system structure is much more vulnerable to wind load.
What is flexible PV module support structure?
Under the circumstance, the span of the fixed PV supports is too small, which leads to the innovative use of flexible PV module support structure. The concept of flexible PV support structure was first introduced by Baumgartner [7, 8, 9] in which the PV panels were supported by cables (see Figure 1).
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.
Do flexible PV support structures deflection more sensitive to fluctuating wind loads?
This suggests that the deflection of the flexible PV support structure is more sensitive to fluctuating wind loads compared to the axial force. Considering the safety of flexible PV support structures, it is reasonable to use the displacement wind-vibration coefficient rather than the load wind-vibration coefficient.
Do flexible PV support structures amplify oscillations?
The research explores the critical wind speeds relative to varying spans and prestress levels within the system. 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.
