Get to know photovoltaic brackets

The photovoltaic bracket is relatively simple to understand, so I won’t describe it in too much detail.

Photovoltaic brackets are divided into fixed brackets and tracking brackets.

The fixed bracket is self-explanatory. Tracking the bracket requires the bracket to be like a sunflower, with the flowers (the front of the solar module) moving along with the sun.

Photovoltaic bracket requirements are also relatively high:

On the one hand, photovoltaic brackets need to be used in specific environments for a long time and have strong mechanical properties such as resistance to wind pressure, snow pressure, earthquake resistance, and corrosion resistance to ensure normal operation in various harsh environments such as sand, rain, snow, and earthquakes. , and the service life is generally required to reach more than 25 years.

On the other hand, photovoltaic brackets play an important role in the construction of photovoltaic power stations. The product quality and design and installation requirements of photovoltaic brackets must comply with the climate environment, building regulations, photovoltaic power design and other standards of the project site. Photovoltaic brackets carry the main power generation of photovoltaic power stations. The product quality, structural design, and layout of photovoltaic brackets directly affect the power generation efficiency, operation safety, and service life of photovoltaic power stations. Choosing suitable photovoltaic brackets and scientific and reasonable design and installation can not only reduce project costs and improve power generation efficiency, but also reduce later operation and maintenance costs.

The design requirements for the fixed bracket and tracking bracket are as follows:

(2) Craftsmanship and cost

The fixed bracket technology mainly includes: mechanical design, mechanical processing and outsourcing galvanizing. Tracking brackets require three more processes than fixed brackets: electronic control design, drive contact, and supporting assembly.

Raw material procurement and outsourcing galvanizing are the main cost components. The main raw material is steel; costs such as labor and equipment depreciation account for a relatively low proportion; as steel processed products, the transportation cost of photovoltaic brackets accounts for a relatively high cost.

In the tracking bracket, the purchase cost of the rotation deceleration device and the control box accounts for about 25% of the raw material cost of the tracking bracket.
