6 FAQs about [Photovoltaic flexible bracket failure case]
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 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.
What is a flexible PV mounting structure?
Flexible PV Mounting Structure Geometric Model The constructed flexible PV support model consists of six spans, each with a span of 2 m. The spans are connected by struts, with the support cables having a height of 4.75 m, directly supporting the PV panels. The wind-resistant cables are 4 m high and are connected to the lower ends of the struts.
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 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.
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.
