6 FAQs about [What is the photovoltaic support back rod]
How many rods are in a photovoltaic axis bar?
The axis bar is composed of 11 shaft rods. Photovoltaic panels are installed on the photovoltaic support purlins. The reciprocating rotation (tilt angle) of the axis bar allows the panel to receive direct sun. The structure is symmetrical with respect to the axis bar, and the axis bar provides a fixed axis for torsional deformation.
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 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.
Why is a photovoltaic support system prone to torsional vibrations?
Due to the lower natural frequencies and torsional stiffness, the system is susceptible to significant torsional vibrations induced by wind. Currently, most existing literature on tracking photovoltaic support systems mainly focuses on wind tunnel experiments and numerical simulations regarding wind pressure and pulsation characteristics.
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.
Do I need a grounding electrode for a PV array?
While a separate grounding electrode system is still permitted to be installed for a PV array, per 690.47 (B), it is no longer required to be bonded to the premises grounding electrode system. In PV systems with string inverters, the equipment grounding conductor from the array terminates to the inverter’s grounding bus bar.
