Tracking photovoltaic bracket

1. Types and characteristics
Tracking photovoltaic brackets are mainly divided into the following types:

Centralized tracking type:
Application scenario: Mainly used in large photovoltaic power stations.
Features: A single beam or longitudinal beam is used to support dozens of photovoltaic modules. The entire system only needs to set up a set of tracking devices, and automatic tracking is performed through the precisely calculated two-point and single-point tracking control technology. It has the characteristics of fast response and simple operation.
Dispersed tracking type:
Application scenario: Suitable for small and medium-sized photovoltaic power stations.
Features: There are two tracking modes: single-axis and dual-axis. The single-axis bracket has low wind resistance and is suitable for areas with high wind speed; the dual-axis bracket can track light sources in multiple directions to improve power generation efficiency. This type of bracket adopts a distributed control system, and completes the adjustment of each photovoltaic panel through the coordinated action of multiple controllers and actuators to ensure system stability and adapt to complex and changing environments.
Dual-axis tracking type:
Application scenario: Mainly used in areas with low light intensity such as high mountains and the Arctic and Antarctic regions.
Features: The dual-axis tracking technology can adapt to the layered progressive control strategy, track factors such as changes in the sun-earth angle and the influence of clouds, and has higher energy capture efficiency. At the same time, the bracket also uses high-precision positioning equipment such as GPS satellite positioning and tilt sensors to improve tracking accuracy and stability.

2. Price range
The price of tracking photovoltaic brackets varies depending on factors such as type, material, brand and customization requirements. According to the latest market data (as of June-July 2024), the price range is roughly as follows:

Single or small bracket: The price may range from a few yuan to a few hundred yuan, suitable for small-scale or experimental applications.
Medium-sized bracket system: The price may range from a few thousand yuan to tens of thousands of yuan, suitable for small and medium-sized photovoltaic power stations.
Large bracket system: The price may reach tens of thousands of yuan to hundreds of thousands of yuan, or even higher, suitable for large photovoltaic power stations or special demand scenarios.
Please note that the above prices are for reference only, and the specific prices need to be determined according to actual needs and market conditions.

3. Technical content and development trend
The realization of tracking photovoltaic bracket technology requires progress in multiple fields such as machinery, electronics, control and communication, and needs to fully consider multiple factors such as climate, terrain, wind force, wind direction, etc. With the continuous advancement of technology and the reduction of costs, the application of tracking photovoltaic brackets in the field of solar photovoltaic power generation will become more and more extensive. In the future, tracking photovoltaic brackets will pay more attention to the development of intelligence, automation and efficiency to further improve power generation efficiency and reduce costs.

4. Selection suggestions
When choosing a tracking photovoltaic bracket, it is recommended to consider the following aspects:

Application scenario: Choose a suitable bracket type according to the scale and terrain characteristics of the photovoltaic power station.
Performance parameters: Pay attention to key indicators such as the tracking accuracy, stability, and wind pressure resistance of the bracket.
Brand and after-sales service: Choose well-known brands and suppliers that provide high-quality after-sales service.
Cost-effectiveness: Choose products with high cost-effectiveness on the premise of meeting performance requirements.
