The essence of photovoltaic power plant design lies in its structural design, which is mainly reflected through photovoltaic brackets.

takePhotovoltaic bracketIt is not an exaggeration to compare it to the "skeleton" of a photovoltaic power station. An excellent support system not only concerns the operational safety and damage rate of components, but also directly affects construction investment. Choosing the appropriate support system can effectively improve the power generation efficiency of the power plant, while reducing engineering and construction costs. It can also significantly reduce maintenance costs in the later stage, thereby increasing the investment return throughout the entire lifecycle.

With the expected significant increase in China's centralized photovoltaic installed capacity in 2023, this trend means that the construction of large-scale centralized ground power stations will enter a climax, thereby promoting the widespread application of tracking support systems. The demand for photovoltaic brackets in the global market is also showing a sustained growth trend.

The service life of photovoltaic brackets is generally required to reach 25 years or more, while also meeting various standards of the project site.

Photovoltaic brackets are not only used for fixing and rotating photovoltaic modules, but also need to operate stably in specific environments for a long time. They must have excellent mechanical properties such as wind pressure resistance, snow pressure resistance, earthquake resistance, and corrosion resistance to ensure normal operation under adverse weather conditions.

According to whether the bracket includes an electronic control and driving system to achieve automatic tracking of solar motion, photovoltaic brackets can be divided into two types: fixed brackets and tracking brackets.

In order to achieve higher power generation efficiency, the inclination angle of the fixed bracket needs to be accurately calculated based on the local latitude and solar altitude. The fixed photovoltaic bracket calculates the optimal incident angle based on lighting resources to install photovoltaic modules and receive the maximum amount of solar radiation.

Fixed bracketAccording to the inclination angle setting, it can be further divided into the optimal inclination angle fixed type, inclined roof fixed type, and inclination angle adjustable fixed type.

During installation, it is necessary to combine the geographical environment and climatic conditions of the project location to fix the components at a specific angle to ensure maximum reception of solar radiation. Although the fixed bracket does not include an electronic control and drive system for automatically adjusting the tilt angle, some fixed adjustable bracket solutions have manual or remote adjustment functions, and can be adjusted manually or by an electric motor.

Tracking photovoltaic bracketBeing able to track the direction of the sun and rotate photovoltaic modules to maximize the reception of solar radiation.

Compared with fixed brackets, tracking brackets also involve electrical control design and drive design, so their upstream raw materials also include control boxes and rotary reducers.

Automatic tracking bracket is a more advanced technology that combines the bracket structure with integrated astronomical algorithms, angle sensors, and other control devices. This bracket can rotate with the sun, keeping the photovoltaic modules always perpendicular to the sunlight, thereby eliminating the cosine loss of the fixed power station.

The tracking system market mainly includes single axis tracking systems and dual axis tracking systems, among which single axis tracking systems are further divided into flat single axis and oblique single axis.

The tracking bracket has significant power generation gain advantages, but the cost is also correspondingly high. With the decrease in tracking system costs and the improvement in reliability, the market share of tracking brackets is expected to increase.
