1. Structural mechanics analysis of photovoltaic bracket design

As an important structure for carrying photovoltaic components, the safety and stability of photovoltaic brackets directly affect the life and performance of the power generation system. Industrial and commercial photovoltaic systems are generally installed on a large scale, and the brackets need to withstand natural forces such as wind loads and snow loads. According to the "Design Specifications for Solar Photovoltaic Systems", the design needs to accurately calculate the greater wind pressure and snow weight to ensure that the bracket does not deform or collapse in extreme climates. For example, the average annual wind speed in Guangdong exceeds 6m/s, and the design wind pressure should consider a 30% safety margin. Using finite element analysis (FEA) technology to simulate the stress of the bracket can effectively prevent structural failure and improve durability. The material is made of high-strength galvanized steel or aluminum alloy, which has excellent corrosion resistance and is suitable for long-term outdoor use.

2. Selection of bracket materials and anti-corrosion technology

In industrial and commercial photovoltaic projects, the choice of bracket materials directly affects the durability and maintenance cost of the system. Common materials include galvanized steel, aluminum alloy and stainless steel. Data shows that galvanized steel brackets account for more than 70% of the market share because of their low cost and good mechanical properties. For different environments, effective anti-corrosion measures must be taken, such as hot-dip galvanizing, spraying polymer coatings, etc., to resist the erosion of rain, acid rain and industrial pollution. The hot and humid environment in the south is particularly demanding on material anti-corrosion, and the service life of untreated steel is often less than 10 years. Choosing a suitable anti-corrosion process can extend the life of the bracket to more than 15 years, significantly reducing long-term operation and maintenance costs.

3. Module installation method and angle optimization design

The photovoltaic bracket is not only a supporting structure, but also needs to ensure the best light receiving angle of the component to improve the power generation efficiency. Industrial and commercial rooftop and ground photovoltaic installations often adopt a fixed angle design, and the angle adjustment is usually based on the local latitude and seasonal sunshine changes. Studies have shown that if the installation angle of the fixed bracket is adjusted to within 5° deviation of the local latitude, the annual power generation efficiency can be increased by about 3%. In recent years, the adjustable tracking bracket has emerged, which can dynamically adjust the angle of the component according to the sun's trajectory, and the annual power generation can be increased by 5-15%, but the cost and maintenance complexity are relatively high. Reasonable selection of fixed or tracking brackets needs to be weighed in combination with budget and site conditions.

4. Rapid installation technology and modular design

Industrial and commercial photovoltaic projects are usually large-scale, and the construction period directly affects the project benefits. The use of modular design and rapid installation technology can significantly shorten the construction time and reduce labor costs. For example, the prefabricated bracket components adopt a plug-in design, which does not require welding and complex tools, and the on-site assembly speed is increased by more than 40%. Data shows that after a 1MW industrial and commercial photovoltaic power station uses a fast installation bracket, the total installation time is shortened from 30 days to 18 days. At the same time, the modular design facilitates transportation and storage, adapts to the flexible installation requirements of different sites, and improves construction efficiency and site safety.

5. Intelligent monitoring and maintenance management of brackets

With the development of smart energy, some advanced industrial and commercial photovoltaic projects have begun to introduce intelligent monitoring systems for brackets. Sensors are used to detect the stress, deformation and environmental conditions of the bracket structure in real time, and abnormalities are warned in time to avoid potential safety risks. For example, after a large photovoltaic station applied intelligent monitoring, the fault response time was increased to within 1 hour, and the maintenance efficiency was increased by 30%. Combined with big data analysis, maintenance plans can be optimized and operation and maintenance costs can be reduced. The application of intelligent management systems is becoming a key technical trend to improve the long-term stability and economy of industrial and commercial photovoltaic projects.

Practical suggestions: key points for efficient design and implementation of photovoltaic brackets

Conduct detailed structural mechanics analysis to ensure that the bracket can withstand the local greater wind and snow loads and ensure equipment safety.

Select high-quality anti-corrosion materials, especially in humid or industrial environments, to extend the service life of the bracket.

Reasonably determine the installation angle of the components, combine fixed angle and tracking technology to maximize power generation efficiency.

Adopt modular design and fast installation process to reduce construction period and cost and improve return on investment.

Introduce intelligent monitoring system to monitor the operation status of the bracket in real time and improve maintenance response speed and economy.
