Solar photovoltaic support steel structure

What are solar support structures?

Solar support structures are an optimal solution for various applications such as parking garages, solar farms, carports, canopies, charging stations, ground mounts, and roof mounts at Nucor Buildings Group. Our projects range from highly architectural solar canopies to large institutional, commercial and utility scale solar installations.

Which material should be used for photovoltaic (PV) support structures?

When it comes to selecting the material for photovoltaic (PV) support structures, it generally adopts Q235B steel and aluminum alloy extrusion profile AL6005-T5. Each material has its advantages and considerations, and the choice depends on various factors. Let’s compare steel and aluminum for PV support structures:

Are ground mounting steel frames suitable for PV solar power plant projects?

In the photovoltaic (PV) solar power plant projects, PV solar panel (SP) support structure is one of the main elements and limited numerical studies exist on PVSP ground mounting steel frames to be a research gap that has not be addressed adequately in the literature.

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.

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 %.
