In a photovoltaic power generation system, a fixed bracket is an important structure for supporting and fixing photovoltaic modules. Its stability and reliability are directly related to the operating efficiency and service life of the entire system. In order to ensure that photovoltaic modules can operate stably in various natural environments and external conditions, fixed brackets have been comprehensively optimized in terms of material selection, structural design, installation process, and wind and snow resistance, so that they can provide solid and reliable support for photovoltaic systems.First of all, the material selection of fixed brackets is the basis for ensuring the stable installation of the system. High-quality photovoltaic brackets usually use metal materials such as high-strength steel or aluminum alloy. These materials have good tensile strength and compressive resistance and can maintain structural integrity after long-term exposure to outdoor environments. In addition, the surface of the bracket is usually hot-dip galvanized or sprayed to enhance its anti-corrosion and anti-rust capabilities, thereby improving the durability of the overall structure. This combination of material and surface treatment allows the bracket to remain stable in the face of natural factors such as moisture, salt spray, and ultraviolet rays, and will not affect the installation firmness of the photovoltaic system due to material aging.Secondly, the structural design of the fixed bracket fully considers mechanical balance and force distribution. The overall configuration of the bracket has been scientifically calculated to ensure that it can effectively disperse the pressure from external loads such as wind and snow while bearing the weight of the photovoltaic modules. Reasonable force design not only improves the bearing capacity of the bracket, but also avoids deformation or fracture caused by local stress concentration. In addition, the connection parts of the bracket adopt high-strength bolts or welding processes to ensure that the connection between the components is tight and reliable, and will not loosen or fall off due to vibration or external force. This structural optimization allows the entire photovoltaic system to remain stable in the face of extreme weather.Furthermore, the installation method of the fixed bracket also plays a decisive role in the stability of the system. The bracket is usually fixed to the ground or roof by pre-buried anchor bolts, concrete foundations or ground piles to ensure a firm connection between it and the ground. Under different terrain and geological conditions, the installation method can be flexibly adjusted to meet the needs of different projects. For example, in a soft soil environment, the use of deep buried piles can enhance the stability of the bracket; on a rock or concrete roof, it can be fixed by pre-buried parts or expansion bolts. This installation strategy adapted to local conditions enables the bracket to adapt to a variety of complex environments and ensure the long-term stable operation of the photovoltaic system.It is worth noting that the fixed bracket also takes special consideration of wind and snow resistance during the design process. Photovoltaic brackets are exposed to the outdoors for a long time and must be able to withstand the pressure brought by wind and snow. Therefore, the windward side of the bracket usually adopts a low wind resistance design to reduce the impact of wind on the overall structure. At the same time, the height and inclination of the bracket are also reasonably planned to facilitate the natural sliding of snow and avoid structural burden caused by excessive snow. These design details not only improve the bracket's ability to resist wind and snow, but also provide a strong guarantee for the safe operation of the photovoltaic system.In addition, the installation angle and direction of the fixed bracket also affect the power generation efficiency and structural stability of the photovoltaic system. The inclination angle of the bracket is usually optimized according to the local solar radiation angle to improve the light absorption efficiency of the photovoltaic module. At the same time, a reasonable inclination design also helps drainage and dust prevention, reducing the impact of rainwater accumulation and dust coverage on power generation performance. The orientation of the bracket is adjusted according to the geographical environment and lighting conditions to ensure that the photovoltaic module is always in the best working condition. This design concept that takes into account both power generation efficiency and structural stability makes the fixed bracket not only a supporting structure for the photovoltaic system, but also an important part of improving the overall performance.Finally, the fixed bracket also shows good convenience in maintenance and repair. Due to its simple structure and high degree of component standardization, daily maintenance work is relatively easy, which is convenient for timely discovery and handling of potential problems. For example, whether the connection parts of the bracket are loose or the surface coating is peeling off can be repaired in time through regular inspections, thereby extending the service life of the bracket and ensuring the stable operation of the photovoltaic system. This easy-to-maintain feature makes the fixed bracket highly adaptable and practical in various photovoltaic projects.In summary, the fixed bracket provides a solid support guarantee for the photovoltaic system through the selection of high-strength materials, scientific structural design, stable installation method, optimization of wind and snow resistance, and easy maintenance. It not only ensures the stable installation of photovoltaic modules in various environments, but also lays the foundation for the long-term and efficient operation of the system. With the continuous development of photovoltaic technology, the design and performance of the fixed bracket will continue to be optimized to provide more reliable technical support for the application of clean energy.
