6 FAQs about [Photovoltaic support string structure]
What is a supporting cable structure for PV modules?
Czaloun (2018) proposed a supporting cable structure for PV modules, which reduces the foundation to only four columns and four fundaments. These systems have the advantages of light weight, strong bearing capacity, large span, low cost, less steel consumption and applicability to complex terrain.
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 a tracking photovoltaic support system have vibrational characteristics?
In this study, field instrumentation was used to assess the vibrational characteristics of a selected tracking photovoltaic support system. Using ANSYS software, a modal analysis and finite element model of the structure were developed and validated by comparing measured data with model predictions. Key findings are as follows.
What is a string box in a photovoltaic plant?
String Box. String Boxes represent one of the most important elements in a photovoltaic plant. They are grouping boxes of strings, designed to convey the electricity coming from the photovoltaic strings and direct it to the inverter which will convert the current from direct to alternating.
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.
