What are the functions of photovoltaic support?

The function of the photovoltaic support is to withstand 30 years of damage such as sunlight, corrosion, and strong winds.

There are many materials for brackets, carbon steel Q235 is generally used, and hot-dip galvanizing is used. The average thickness of galvanizing is 65 μm, and the basic thickness of the bracket can be equal to or greater than 2.5mm. It has excellent compression resistance, strong wind resistance, and corrosion resistance.

Introduction of solar battery holder accessories

We are no strangers to the photovoltaic bracket, which is a bracket specially used to support solar energy. We can see its complete form, but in fact, its interior is composed of multiple components, each with different functions. The following is an introduction to the photoelectric support accessories:

1. The member used to support the track is called a beam.

2. Guide rails are used to support photovoltaic power generation components.

3. Supports are used to enhance the stability of columns, beams, and guide rails.

4. The fixed bracket is used for the bracket whose inclination and direction cannot be adjusted.

5. Single-axis tracking frame: track with one axis as the center.

6. Dual-axis tracking frame: it is a device that tracks two axes at the center.

7. Column: It is a component connected to the foundation to support beams, shafts, and tracks.

8. Shaft: A part used to support the guide rail and adjust the inclination angle of the guide rail, suitable for installation on the tracking bracket.

9. Connecting rod: It is used for the mechanical transmission part between the frame and the frame and the power system to track the frame.

10. Accessories: In order to form a continuous bracket system, the connection between the straight part and the curved part, fix the straight part and the curved part or supplement the functions of the straight part and the curved part, and the parts have a straight connecting plate and a hinge connection Plates, turning joint plates, variable angle joint plates, partition walls, pressure plates, fasteners.

11. Bracket: A system used to support solar cell modules, which includes pillars, brackets, beams, shafts, guide rails, attachments, etc., all of which are made of metal materials.
