With the global pursuit of carbon neutrality goals, the photovoltaic (PV) industry has entered a stage of high-quality development. As a core component that improves the efficiency of PV power generation, the photovoltaic tracking system relies heavily on the performance and reliability of its key parts. High-precision forging technology, with its unique advantages in material utilization, structural strength and dimensional accuracy, has become an indispensable support for the manufacturing of key parts of PV tracking systems, injecting strong impetus into the upgrading of the PV industry.

Key parts of photovoltaic tracking systems, such as slewing bearings, drive shafts and connecting rods, are often in harsh working environments, bearing alternating loads, wind loads and temperature changes for a long time. This puts forward strict requirements on their mechanical properties and service life. High-precision forging technology realizes the precise forming of metal materials through advanced process control and professional die design. During the forging process, the metal structure is refined, internal defects such as porosity and shrinkage are eliminated, and the density and toughness of the parts are significantly improved. Compared with traditional casting or machining processes, high-precision forged parts have higher fatigue resistance and wear resistance, which can effectively reduce the failure rate of PV tracking systems and extend their service life.

In the production of slewing bearings, a key part of PV tracking systems, high-precision forging technology plays a crucial role. The slewing bearing is responsible for supporting the PV module and realizing the rotation and positioning of the tracking system. Its dimensional accuracy directly affects the tracking accuracy of the system and thus the power generation efficiency. Through high-precision forging, the inner and outer rings of the slewing bearing can be formed in one step, ensuring the coaxiality and parallelism of the parts. At the same time, the forged slewing bearing has a more uniform material structure, which enhances its load-bearing capacity and rotation flexibility, enabling the tracking system to respond more sensitively to changes in sunlight angle and improve the light-receiving efficiency of PV modules.

The application of high-precision forging technology also brings significant economic and environmental benefits to the photovoltaic industry. On the one hand, the high material utilization rate of precision forging reduces the waste of raw materials, lowers the production cost of key parts, and further promotes the cost reduction and efficiency increase of the entire PV industry chain. On the other hand, the long service life of high-precision forged parts reduces the frequency of maintenance and replacement of PV tracking systems, reducing the generation of construction waste and the energy consumption of subsequent maintenance, which is in line with the concept of green and low-carbon development.

Looking to the future, with the continuous advancement of the photovoltaic industry towards high power, high efficiency and intelligence, the demand for key parts of PV tracking systems will be further upgraded, and higher requirements will be put forward for high-precision forging technology. It is expected that through the continuous innovation and optimization of forging processes, equipment and materials, high-precision forging technology will play a more important role in improving the performance of PV tracking systems, promoting the healthy development of the photovoltaic industry, and helping to achieve global energy transformation and carbon neutrality goals.
