How adaptable is the tracking photovoltaic bracket under different climatic conditions?
Publish Time: 2025-01-29
The tracking photovoltaic bracket is a system that can automatically adjust the angle of the photovoltaic panel according to the position of the sun to maximize the efficiency of solar energy collection.
1. Temperature changes
High temperature conditions: In high temperature environments, the efficiency of photovoltaic cells will decrease. Tracking brackets can reduce the surface temperature of the panel and improve power generation efficiency by optimizing the angle. However, high temperatures will also put pressure on the bracket materials and drive systems, which may cause problems such as material expansion, lubricant evaporation, and motor overheating. Therefore, the bracket materials and drive systems need to have good high temperature resistance, and heat dissipation measures should be considered in the design.
Low temperature conditions: In low temperature environments, the efficiency of photovoltaic cells may increase, but extreme low temperatures may cause the bracket materials to become brittle, especially metal materials. In addition, low temperatures may cause the fluidity of the hydraulic system or lubricating oil to decrease, affecting the normal operation of the bracket. Therefore, the bracket material should have good low temperature resistance and use lubricants suitable for low temperature environments.
2. Precipitation and humidity
Rainfall and snow accumulation: In areas with more rain and snow, the bracket design needs to consider drainage and snow removal functions. Snow accumulation may cover the photovoltaic panels, affect the power generation efficiency, and may even cause the bracket structure to overload. Tracking systems should have automatic snow removal functions or be designed to withstand the weight of snow. In addition, the waterproof performance of the bracket is also very important, especially in the electrical connection and drive system.
Humidity and high humidity environment: High humidity environment may cause corrosion of metal parts and moisture in electrical components, affecting the reliability and life of the system. Therefore, the bracket material should have good anti-corrosion performance, and the electrical part should be strictly protected, such as using waterproof sealants and moisture-proof materials.
3. Wind conditions
Strong wind and high wind speed environment: Strong winds may generate huge wind loads on photovoltaic brackets, especially when the bracket is adjusted to the maximum windward angle. The design of the tracking bracket needs to consider the impact of wind loads to ensure that the structure will not be unstable or damaged under strong wind conditions. Usually, the bracket will adopt a more sturdy structural design or automatically adjust to the minimum windward angle under extreme wind conditions.
Sandy areas: In areas with strong winds, sand and dust may affect the power generation efficiency of photovoltaic panels, and wind and sand will also cause wear and tear on the mechanical parts and electrical systems of the bracket. The design of the tracking bracket should consider dust prevention measures, such as the use of sealing structures, regular cleaning mechanisms, etc.
4. Lighting conditions
High direct sunlight areas: In areas with abundant sunlight, tracking systems can significantly improve the efficiency of photovoltaic power generation. However, long periods of strong sunlight may cause the temperature of the photovoltaic panels to be too high, affecting the power generation efficiency. The tracking bracket should have a good heat dissipation design to ensure that the panel temperature remains within a reasonable range.
Cloudy and overcast environment: In cloudy or overcast conditions, the position of the sun changes rapidly, and the tracking system needs to respond quickly to adjust the panel angle. In addition, the shadow changes in cloudy weather may cause local shading effects, affecting the power generation efficiency. The tracking system should have a sensitive control system that can cope with rapid changes in the position of the sun.
5. Extreme climatic conditions
Sandstorm and desert areas: In areas with frequent sandstorms such as deserts, sand and dust may cause serious pollution to photovoltaic panels and brackets, affecting the power generation efficiency. Tracking brackets should have automatic cleaning functions or be designed to be easy to clean manually. In addition, the bracket material should have good corrosion resistance and wear resistance.
Typhoon and hurricane areas: In these extreme wind conditions, the bracket must have extremely high wind resistance. The design needs to consider the calculation of wind loads and adopt a reinforced structure. It may also be necessary to adjust the bracket to the minimum windward angle before the typhoon arrives to reduce the impact of wind.
6. Earthquakes and other natural disasters
Earthquake-prone areas: In earthquake-prone areas, photovoltaic brackets need to have good seismic resistance to prevent structural damage caused by earthquakes. The ground-fixed part of the bracket should be designed to be seismic-resistant to ensure that it will not collapse or deform severely when an earthquake occurs.
7. Maintenance and care
Maintenance requirements under different climatic conditions: The maintenance requirements of tracking photovoltaic brackets will also vary under different climatic conditions. For example, in humid areas, electrical components may need to be checked and replaced more frequently; in windy and sandy areas, photovoltaic panels and brackets may need to be cleaned more frequently. Therefore, the bracket design should consider easy maintenance and care to reduce long-term operating costs.
By comprehensively considering these factors, photovoltaic brackets can achieve efficient and stable solar energy collection under various climatic conditions and maximize power generation efficiency.
