6 FAQs about [Photovoltaic support transmission equipment]

What are the different types of PV support systems?

At present, there are three main types of PV support systems: fixed mounted PV, flexible mounted PV, and float-over mounted PV systems. Fixed mounted PV systems are the traditional and most widely used PV system. They are usually mounted on the ground and building roofs.

What is cable-supported photovoltaic (PV)?

Cable-supported photovoltaic (PV) modules have been proposed to replace traditional beam-supported PV modules. The new system uses suspension cables to bear the loads of the PV modules and therefore has the characteristics of a long span, light weight, strong load capacity, and adaptability to complex terrains.

What is a PV support structure?

Support structures are the foundation of PV modules and directly affect the operational safety and construction investment of PV power plants. A good PV support structure can significantly reduce construction and maintenance costs. In addition, PV modules are susceptible to turbulence and wind gusts, so wind load is the control load of PV modules.

What is a tracking photovoltaic support system?

The tracking photovoltaic support system ( Fig. 1) is mainly composed of an axis bar, PV support purlins, pillars (including one driving pillar in the middle and nine other non-driving pillars), sliding bearings and a driving device. The axis bar is composed of 11 shaft rods. Photovoltaic panels are installed on the photovoltaic support purlins.

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 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 %.
