Solar tracking photovoltaic brackets
In the early days, most photovoltaic brackets were of fixed structure, designed simply and at low cost. As subsidies have been phased out, the market's demand for profitability and efficiency of power plants has increased, making tracking brackets increasingly important in the market.
Currently, the global market ratio of photovoltaic tracking brackets to fixed brackets is approximately 4:6. By 2025, this ratio is expected to reach 5:5, or even higher. Compared to fixed brackets, tracking brackets have higher requirements in both software and hardware.
Therefore, the following aspects need to be addressed:
Intelligent control system: The main difference between tracking brackets and fixed brackets lies in the unique tracking control system, which not only protects the tracking brackets but also tracks the sunlight based on the position of the sun. Additionally, it should optimize and adjust the tracking through self-learning based on different terrains, installation errors, weather, and seasons to ensure higher power generation.
Structural stability: Compared to fixed brackets, the tracking system has lower frequency and damping ratio, which requires higher stability in structural design.
Rapid maintenance: The tracking system is equipped with a drive mechanism, adopting a modular motor design that reduces maintenance costs and improves maintenance efficiency. It also utilizes a multi-point drive scheme and multi-point electric interlock protection to enhance fault monitoring capabilities. Maintenance can be performed by one person without special tools. Consequently, the system's frequency and damping ratio can be significantly improved, and its wind resistance is better enhanced.
