6 FAQs about [Inclined support on photovoltaic support column]
Does a tracking photovoltaic support system respond to wind-induced loads?
Recent research indicates that the dynamic characteristics of tracking photovoltaic support system, namely inertia, damping, and stiffness, significantly influence the tracking photovoltaic support system's ability to respond to wind-induced loads, affecting its stability, reliability, and overall performance , .
How stiff is a tracking photovoltaic support system?
Because the support structure of the tracking photovoltaic support system has a long extension length and the components are D-shaped hollow steel pipes, the overall stiffness of the structure was found to be low, and the first three natural frequencies were between 2.934 and 4.921.
What are the dynamic characteristics of photovoltaic support systems?
Key findings are as follows. Dynamic characteristics of tracking photovoltaic support systems obtained through field modal testing at various inclinations, revealing three torsional modes within the 2.9–5.0 Hz frequency range, accompanied by relatively small modal damping ratios ranging from 1.07 % to 2.99 %.
Does inclination affect the natural frequency of photovoltaic support systems?
Moreover, the variations in inclination of tracking photovoltaic support systems had minimal impact on their natural frequencies, as the increase in natural frequency magnitude across different inclinations remained below 1.5 %. Additionally, consistently low modal damping ratios were measured, ranging from 1.07 % to 2.99 %.
How many pillars does a photovoltaic support system have?
The tracking photovoltaic support system consisted of 10 pillars (including 1 drive pillar), one axis bar, 11 shaft rods, 52 photovoltaic panels, 54 photovoltaic support purlins, driving devices and 9 sliding bearings, and also includes the connection between the frame and its axis bar. Total length was 60.49 m, as shown in Fig. 8.
What is the tilt angle of a photovoltaic support system?
The comparison of the mode shapes of tracking photovoltaic support system measured by the FM and simulated by the FE (tilt angle = 30°). The modal test results indicated that the natural vibration frequencies of the structure remains relatively constant as the tilt angle increases.
