4 Frequently Asked Questions about “Structural principle of flat single-axis photovoltaic support - RRR Renewable Projects (SA)”
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 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.
Does tilt angle affect the dynamic characteristics of the tracking photovoltaic support system?
However, the corresponding vibration mode-shapes obtained from both methods remain similar, indicating that the tilt angle is of small impact on the dynamic characteristics parameters of the tracking photovoltaic power generation bracket tracking photovoltaic support system.
