6 FAQs about [Photovoltaic bracket diagonal support length requirements]
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 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 %.
What are the dynamic characteristics of the tracking photovoltaic support system?
Through processing and analyzing the measured modal data of the tracking photovoltaic support system with Donghua software, the dynamic characteristic parameters of the tracking photovoltaic support system could be obtained, including frequencies, vibration modes and damping ratio.
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.
What is the modal damping ratio of a photovoltaic support system?
Additionally, consistently low modal damping ratios were measured, ranging from 1.07 % to 2.99 %. Secondly, modal analysis of the tracking photovoltaic support system was performed using ANSYS v2022 software, resulting in the determination of structural natural frequencies and mode shapes.
What is the damping ratio of a tracking photovoltaic support system?
Moreover, the measured damping ratios associated with each mode was low, amounting to no more than 3.0 %. Table 1. The measured natural frequency and damping ratio of a tracking photovoltaic support system at different tilt angles (Frequency /H z; Damping ratio /%). Fig. 5.
