Significant Cost Advantage: The structure of the fixed photovoltaic bracket system is relatively simple, without the need for complex drive systems and control systems to realize the angle tracking of components. This gives it obvious advantages in terms of material costs. Generally, only conventional materials such as aluminum alloy, carbon steel, and stainless steel are needed, and the amount of materials used is relatively small. At the same time, the simple structural design also greatly reduces the difficulty and cost of installation. During the installation process, fewer man-hours and professional equipment are required, and the installation work can be completed quickly, thus effectively reducing the overall construction cost of the project. For example, in some small distributed photovoltaic projects, the cost advantage of fixed photovoltaic bracket systems is particularly prominent, making the project's investment return rate higher and attracting many individual and corporate investors.

High Stability and Durability: Since there are no complex mechanical moving parts, the fixed photovoltaic bracket system is more stable and reliable during operation. When facing various natural environmental factors such as strong winds, heavy rains, and sandstorms, the fixed bracket can provide reliable support for photovoltaic modules with its solid structure and stable installation method, effectively reducing the risk of component damage due to external impact. Taking the photovoltaic power station built in coastal areas as an example, the fixed photovoltaic bracket system, after special wind-resistant design, can resist strong typhoons and ensure the normal operation of the photovoltaic power station under severe weather conditions. Moreover, its durability is also excellent. After long-term exposure to the sun, rain, wind, and snow, it can still maintain good performance, reducing the cost of later maintenance and replacement, and providing a strong guarantee for the long-term stable operation of the photovoltaic power station.

Easy Maintenance: The maintenance work of the fixed photovoltaic bracket system is relatively easy. The absence of moving parts means that there is no need to worry about component wear, failures, etc., and there is no need for complex regular debugging and calibration work. Daily maintenance mainly focuses on checking the bracket structure, such as checking for loose or corroded components, as well as cleaning and inspecting photovoltaic modules to ensure that the component surface is free of dust and debris, ensuring power generation efficiency. Under normal circumstances, only regular simple inspections and cleaning work are needed to maintain the normal operation of the fixed photovoltaic bracket system, which greatly reduces the difficulty and cost of operation and management. This is of great advantage for some photovoltaic power stations located in remote areas where maintenance personnel are difficult to reach, and can effectively ensure the continuous and stable power generation of the power station.

Distributed Photovoltaic Power Generation Projects: Fixed photovoltaic bracket systems are widely used in the field of distributed photovoltaic power generation. Whether it is the roof of industrial and commercial buildings in cities or the roofs of rural residents, fixed photovoltaic brackets can be well adapted. In industrial and commercial roof projects, due to the relatively large and flat roof area, the fixed photovoltaic bracket system can be flexibly arranged according to the orientation and structural characteristics of the roof, and photovoltaic modules can be installed efficiently. This provides a large amount of self-used electricity for enterprises, reduces their electricity costs, and the excess electricity can also be sold online to increase enterprise income. In rural residential roof projects, the simple installation and low maintenance characteristics of fixed photovoltaic bracket systems make them very suitable for the actual situation in rural areas. Farmers only need to install fixed photovoltaic brackets and photovoltaic modules on their own roofs to easily realize photovoltaic power generation, which not only meets household electricity needs but also obtains additional income through surplus electricity 上网，becoming an important means to develop clean energy and promote rural revitalization in rural areas.

Large-Scale Ground Photovoltaic Power Stations: Fixed photovoltaic bracket systems also play an important role in the construction of large-scale ground photovoltaic power stations. Especially in some areas with relatively flat terrain, abundant solar energy resources, and relatively low land costs, such as the northwest desert areas and the North China Plain in China, large-scale adoption of fixed photovoltaic bracket systems to build photovoltaic power stations has significant advantages. These areas have vast land resources, which can provide sufficient space for the large-scale laying of fixed photovoltaic bracket systems. Through reasonable planning and layout, the fixed photovoltaic bracket system can support a large number of photovoltaic modules, form large-scale photovoltaic power generation capacity, transmit a large amount of clean electricity to the power grid, strongly promote the green development of the local energy industry, and help achieve the national energy transformation goal.

Photovoltaic Applications in Special Environments: Fixed photovoltaic bracket systems also show good adaptability in some special environments. For example, in high-altitude areas, due to the thin air and high solar radiation intensity, but at the same time, the climate conditions are harsh with strong winds and low temperatures. The fixed photovoltaic bracket system, with its stable structure and simple design, can operate reliably in this environment and provide a guarantee for the local energy supply. In some coastal areas, although facing high humidity, strong salt spray, and other corrosive environments, fixed photovoltaic bracket systems made of corrosion-resistant materials, such as aluminum alloy brackets or carbon steel brackets with special anti-corrosion treatment, can effectively resist the erosion of seawater and sea wind, ensuring the long-term stable operation of the photovoltaic power station. In addition, in some remote island areas, the combination of fixed photovoltaic bracket systems and small energy storage equipment can provide independent and reliable power supply for island residents, solving the problem of difficult power supply in island areas.

Comparison of Power Generation Efficiency: Compared with tracking photovoltaic bracket systems, the power generation efficiency of fixed photovoltaic bracket systems is different to a certain extent. The tracking photovoltaic bracket system can track the sun's position in real-time and actively adjust the orientation of the components, so that the photovoltaic components always maintain a vertical or nearly vertical angle with the sunlight, thereby maximizing the use of solar radiation and increasing power generation. Research data shows that the power generation gain of tracking bracket systems is usually between 5% and 35%, among which the dual-axis tracking bracket has the best effect, with a power generation ratio of 130% to 135%. However, due to the fixed angle of the fixed photovoltaic bracket system, it cannot adjust in real-time according to the change of the sun's position. During some periods of the day, the angle between the photovoltaic module and the sunlight is not optimal, resulting in relatively low power generation efficiency. However, under certain conditions, the power generation efficiency of the fixed photovoltaic bracket system can also meet the actual needs. For example, in low-latitude areas, due to the relatively small change in the sun's altitude angle, the fixed photovoltaic bracket system can maintain good power generation performance most of the time by reasonably setting the installation angle, and the gap in power generation efficiency with the tracking bracket system is not obvious.

Cost Comparison: In terms of cost, the fixed photovoltaic bracket system has obvious advantages. As mentioned earlier, the fixed bracket system has a simple structure, low material and installation costs, and relatively low later maintenance costs. The tracking photovoltaic bracket system, on the other hand, needs to be equipped with drive systems, control systems, and complex mechanical structures to realize the tracking function, which greatly increases the cost of the bracket. At the same time, the installation and commissioning of the tracking bracket system require higher technical requirements and professional equipment, further increasing the installation cost. In addition, due to the complexity of the tracking bracket system, its later maintenance and failure rates are relatively high, and the maintenance cost also increases accordingly. According to relevant data statistics, the initial investment cost of the tracking bracket system is about 15% to 20% higher than that of the fixed bracket system. Therefore, in some projects sensitive to cost, especially small distributed photovoltaic projects, the fixed photovoltaic bracket system is the first choice due to its lower cost.

Differences in Applicable Scenarios: There are also certain differences in applicable scenarios between fixed photovoltaic bracket systems and tracking photovoltaic bracket systems. Fixed photovoltaic bracket systems are suitable for various terrain and environmental conditions, especially in areas with abundant land resources and relatively stable solar energy resources, as well as in distributed photovoltaic power generation projects with strict cost control. The tracking photovoltaic bracket system is more suitable for areas with abundant solar energy resources and high direct radiation ratio, such as desert areas, and large-scale ground photovoltaic power station projects with high requirements for power generation. In these areas, the tracking bracket system can give full play to its advantages in power generation efficiency, maximize photovoltaic power generation by tracking the sun in real-time, and thus improve the economic benefits of the project. In addition, the tracking bracket system also has certain application advantages in some projects with limited space but high requirements for power generation efficiency, which can achieve higher power generation in limited space by optimizing component layout and tracking strategies.

Material Innovation: To further improve the performance and durability of fixed photovoltaic bracket systems, material innovation has become an important development direction. In recent years, new materials have continuously emerged and been applied to fixed photovoltaic bracket systems. For example, high-strength aluminum alloy materials, with their advantages of light weight, high strength, and corrosion resistance, have gradually become one of the ideal materials for fixed photovoltaic brackets. Compared with traditional carbon steel materials, aluminum alloy brackets can not only reduce their own weight, reduce transportation and installation difficulties but also maintain good performance in harsh environments and prolong service life. In addition, some composite materials with special properties have also begun to be explored for application in fixed photovoltaic bracket systems. For example, carbon fiber composite materials, with excellent properties such as high strength, low density, and corrosion resistance, can significantly improve the bearing capacity and stability of the bracket, while reducing the weight of the bracket and lowering costs. With the continuous progress of materials science, more high-performance and low-cost new materials will be applied to fixed photovoltaic bracket systems in the future, promoting the continuous improvement of their technical level.

Structural Optimization Design: In terms of structural design, fixed photovoltaic bracket systems are also constantly being optimized and innovated. By using advanced computer-aided design (CAD) and finite element analysis (FEA) technologies, engineers can accurately simulate and optimize the bracket structure, minimizing material usage and reducing costs while ensuring the strength and stability of the bracket. For example, some new fixed photovoltaic brackets adopt a lightweight design concept. By optimizing the shape and size of the bracket and reasonably distributing materials, the weight of the bracket is effectively reduced without affecting its performance. At the same time, innovations and improvements have also been made in the connection methods and installation processes of the brackets. The adoption of new connection technologies, such as modular connection and quick installation connection, not only improves installation efficiency but also enhances the connection reliability of the bracket, reducing potential safety hazards caused by loose connections. In addition, some fixed photovoltaic bracket systems are also designed with adjustable structures, which can fine-tune the installation angle of photovoltaic modules within a certain range to adapt to changes in solar energy resources in different regions and seasons, further improving power generation efficiency.

Integration with Intelligent Technologies: With the wide application of intelligent technologies such as the Internet of Things, big data, and artificial intelligence in the energy field, fixed photovoltaic bracket systems have also begun to gradually integrate with intelligent technologies and develop in the direction of intelligence. By installing sensors in the fixed photovoltaic bracket system, real-time data on the operation of photovoltaic modules, such as temperature, light intensity, and power generation, can be collected and transmitted to the intelligent monitoring platform. Using big data analysis and artificial intelligence algorithms to analyze and process the collected data can timely detect potential problems in photovoltaic modules and bracket systems, and provide early warning information, so that operation and maintenance personnel can carry out maintenance and treatment in a timely manner, improving the operational reliability and stability of the photovoltaic power station. In addition, intelligent technologies can also intelligently control the fixed photovoltaic bracket system according to real-time solar energy resource conditions and power grid demand. For example, when the light intensity is weak or the power grid load is low, the intelligent control system can appropriately adjust the working state of the photovoltaic modules to reduce energy consumption and improve energy utilization efficiency. In the future, the integration of fixed photovoltaic bracket systems with intelligent technologies will be deeper, realizing more intelligent and efficient operation and management.
