Classification And Optimization Design of Zn-al-mg Photovoltaic Brackets

The classification and optimal design of photovoltaic supports is a key research area, with the main purpose of improving the power generation efficiency and reducing costs of photovoltaic systems. Currently, common forms of Zn-Al-Mg photovoltaic brackets include: fixed brackets, fixed and adjustable tilt brackets, tracking brackets, as well as flexible brackets and floating brackets used in special scenarios.

1. Fixed bracket

Fixed brackets are the most common form, and commonly used structural forms include double-column bracket system solutions and single-pile bracket system solutions. The advantages of fixed brackets are simple structure, less subsequent maintenance, and relatively low requirements for foundation accuracy. However, fixed racks have the lowest power generation capacity of all rack types.

2. Fixed adjustable pv panel brackets

The fixed adjustable pv panel brackets is a bracket that can be fine-tuned based on a fixed angle. Common types include slot-fixed, curved beam, jack, and push rod types. This form of bracket allows fine-tuning of the tilt angle according to the actual situation to obtain the best power generation performance.

3. Tracking bracket

The tracking bracket adjusts the tilt angle of the photovoltaic panel in real time according to changes in the solar altitude angle and azimuth angle. Common types include flat single-axis tracking brackets, oblique single-axis tracking brackets and dual-axis tracking brackets. Tracking brackets can maximize the use of solar radiation and improve power generation efficiency, but the system complexity and cost will be relatively high.

4. For the design optimization of fixed brackets, the main purpose is to reduce the amount of steel used to reduce costs while ensuring the safe operation of the bracket. Optimization design mainly considers the following aspects:

Spacing optimization: Select the appropriate bracket spacing by comparing and analyzing the amount of steel used in equally spaced and unequal spacing bracket structures. Smaller bracket spacing will lead to an increase in the purlin cross-section, thereby increasing the amount of steel used.

Optimization of material selection: Select appropriate materials and cross-sectional shapes to reduce the amount of steel used. Conduct a comparative analysis of multiple large and small bracket structures to determine the structure with a smaller amount of steel.

Design parameter optimization: Reduce the amount of steel used by adjusting the design parameters of the bracket, such as the distance between the north and south piles, the cross-sectional shape of the purlins, etc.

5. The classification and optimized design of photovoltaic brackets are very important to improve the power generation efficiency and reduce costs of photovoltaic systems. Different types of brackets have different applicable scenarios and advantages. Design optimization can effectively reduce the amount of steel used and achieve the goal of cost reduction and efficiency improvement. In specific projects, the most suitable bracket form should be selected according to the actual situation, and reasonable design optimization should be carried out.
