As the global demand for renewable energy continues to grow, solar photovoltaic power generation, as a clean and renewable form of energy, has received widespread attention and application. In the solar photovoltaic power generation system, photovoltaic brackets, as an important component, play the role of supporting and fixing photovoltaic components. The selection of photovoltaic brackets has become the focus of many families and businesses. Among the many types of photovoltaic brackets, fixed and tracking types are the most popular. This article will focus on the principles, characteristics and application fields of fixed photovoltaic brackets and tracking photovoltaic brackets, giving you an in-depth understanding of these two technological products and helping you make wise decisions when choosing.
- Fixed photovoltaic bracket
Fixed photovoltaic bracket is one of the most widely used types of photovoltaic brackets. It uses a fixed angle and position to fix the photovoltaic module on the ground or roof to fully receive solar radiation and realize photovoltaic power generation. Fixed photovoltaic bracket has the following characteristics:
1. High stability
The fixed photovoltaic bracket adopts a sturdy structural design and can remain stable under various climatic conditions. Whether it is a rainy summer or a cold winter, the fixed photovoltaic bracket can reliably support the photovoltaic module.
2. Low maintenance cost
Since the fixed photovoltaic bracket has no moving parts, the structure is simple, and the production and installation are relatively convenient, the maintenance cost is relatively low. You only need to regularly check and clean the photovoltaic module to ensure its normal operation.
3. Wide applicability
Fixed photovoltaic brackets do not require high site requirements and are suitable for various sites, including roofs, ground, hillsides, etc. Whether in cities or rural areas, fixed photovoltaic brackets can be flexibly applied.
4. Long life
Fixed photovoltaic brackets have a long service life, generally more than 30 years.
5. Advantages and disadvantages
Advantages: Due to simple structure, high stability and long life, the maintenance cost of fixed photovoltaic brackets is relatively low. At the same time, it has strong adaptability and is suitable for various site conditions, especially for areas with stable sites and low winds.
Disadvantages: Since fixed brackets cannot actively adjust the optimal light receiving angle of photovoltaic equipment, their power generation efficiency will be affected when the lighting conditions are not ideal. In addition, in areas with strong winds or severe cold, additional reinforcement measures may be required to ensure the stability of photovoltaic equipment.
- Tracking photovoltaic bracket
The tracking photovoltaic bracket is a bracket system that can automatically adjust the illumination angle of the photovoltaic equipment according to the position of the sun and the lighting conditions. By tracking the movement of the sun, the tracking photovoltaic bracket can maximize the energy output of the photovoltaic module. The tracking photovoltaic bracket has the following characteristics:
1. High energy output
The tracking photovoltaic bracket can adjust the angle of the photovoltaic module in real time according to the position of the sun, so that it is always facing the solar radiation, thereby maximizing the energy output. Compared with the fixed photovoltaic bracket, the tracking photovoltaic bracket can achieve higher power generation efficiency.
2. Intelligent control
The tracking photovoltaic bracket adopts an intelligent control system that can automatically track the movement trajectory of the sun. Through precise calculation and control, the tracking photovoltaic bracket can achieve the best angle adjustment and improve energy utilization efficiency.
3. Strong wind resistance
The tracking photovoltaic bracket is designed with wind resistance in mind and can remain stable under adverse climatic conditions. At the same time, the tracking photovoltaic bracket can also reduce the impact of wind on photovoltaic modules by adjusting the angle, thereby improving the safety of the system.
4. Strong adaptability
Different types of tracking photovoltaic brackets (such as single-axis, dual-axis, etc.) can be designed according to different climates, terrains and application requirements.
5. Advantages and disadvantages
Advantages: Compared with fixed photovoltaic brackets, the biggest advantage of tracking photovoltaic brackets is their high power generation efficiency. Since they can track the position of the sun in real time and automatically adjust the illumination angle of photovoltaic equipment, their power generation can be increased by about 20%. In addition, the tracking bracket is highly adaptable and can be customized according to different needs.
Disadvantages: Although the tracking photovoltaic bracket has high power generation efficiency, its system complexity is high, so the manufacturing cost and maintenance cost are high. At the same time, since it needs to track the position of the sun in real time, additional reinforcement measures may be required in areas with strong winds to ensure the stability of photovoltaic equipment.
- Application fields
Fixed photovoltaic brackets and tracking photovoltaic brackets play an important role in different application fields.
Fixed photovoltaic brackets are suitable for areas with low wind and stable geology, and can also be used in flat sites such as building roofs and parking lots. In flat sites, fixed photovoltaic brackets can provide stable support and are easy to install. Due to their stability and low maintenance costs, fixed photovoltaic brackets have become the first choice for large-scale photovoltaic power generation.
Tracking photovoltaic brackets are suitable for areas with strong winds and sufficient sunlight. They can improve power generation efficiency and maintain stability in areas with strong winds. They can also be used in application scenarios under complex terrain and special climatic conditions: such as application scenarios under special terrain and climatic conditions such as mountainous areas, deserts, and coastal areas. Tracking photovoltaic brackets are suitable for places with high energy output requirements, such as high-efficiency photovoltaic power stations, photovoltaic agriculture, etc. By tracking the movement of the sun, tracking photovoltaic brackets can maximize energy output and improve the economic benefits of the system.
