When installing solar panels under different climatic conditions, the following key points should be noted:
First, high-temperature areas
Optimize the installation Angle
In summer, due to the large solar altitude Angle, appropriately adjusting the Angle of the solar panels to match the incident Angle of the sunlight can maximize the absorption of solar energy.
Ensure good heat dissipation:
In high-temperature environments, the heat dissipation issue of solar panels is particularly important. When installing, it is necessary to ensure that there is sufficient gap between the panels to facilitate air circulation and help the solar panels dissipate heat effectively.
Regularly cleaning the dust and dirt on the surface of solar panels is also a key to maintaining their heat dissipation performance.
Use high-quality materials:
In high-temperature areas, photovoltaic modules and accessories that are resistant to high temperatures and have stable performance should be selected to ensure long-term stable operation.
Safety protection measures:
During the installation process, staff members need to wear necessary protective equipment, such as safety helmets, gloves and sun-protective clothing, etc.
Make sure the installation site is far away from flammable items and have necessary fire-fighting equipment ready just in case.
Second, cold regions
Large-angle installation
In cold regions, it is recommended to adopt a larger installation Angle (such as above 40 degrees) to increase the daily average temperature of the components, reduce the area covered by snow, and thereby enhance the power generation efficiency.
Prevent snow accumulation and freezing:
When installing, the bottom of the solar panel should be kept a small distance from the ground to allow the snow to slide off and reduce the coverage of the solar panel by the snow.
Regularly clear the accumulated snow to prevent it from covering and freezing the components for a long time, which may affect the power generation.
Use cold-resistant materials:
In cold regions, photovoltaic modules and accessories with good cold resistance should be selected to ensure stable operation in low-temperature environments.
Safety of construction workers
Cold weather can have an impact on the health of construction workers. Construction workers need to wear warm enough clothing, such as cold-proof suits, warm gloves and anti-slip shoes, etc.
Arrange working hours reasonably to prevent construction workers from getting frostbite or fatigue due to working in extremely cold environments for a long time.
Third, humid areas
Select the appropriate installation Angle:
In humid areas, it is recommended to set the component inclination Angle between 25 and 30 degrees to reduce the pollution of rainwater and fog to the panels and lower the power generation efficiency.
Moisture-proof and mold-proof
Ensure that the installation environment is well-ventilated and avoid the components being in a damp environment for a long time.
Regularly check the sealing of the components and junction boxes to prevent water vapor from entering.
Regular maintenance
Regularly clean the dust and dirt on the surface of the components to maintain their cleanliness.
Check the connection of the junction box and cables to ensure reliable electrical connections.
Fourth, areas with strong winds
Reinforcement installation bracket
In areas with strong winds, it is necessary to set a relatively large installation Angle (such as above 40 degrees) to reduce the impact or shaking caused by the wind and extend the service life of the components.
Use wind-resistant materials:
Select photovoltaic modules and bracket materials with good wind resistance to ensure stable operation in strong wind environments.
Reasonable layout
During installation, the layout of the components should be reasonably planned to reduce the stress concentration caused by uneven wind pressure.
Fifth, General Precautions
Select the appropriate installation location:
Installation should be carried out in a place with abundant sunlight and no obstructions. Avoid installation in shaded areas such as trees and buildings.
Ensure the installation quality:
During the installation process, operations should be carried out strictly in accordance with the construction drawings and specifications to ensure the accuracy and reliability of the installation.
Use appropriate connecting bolts and nuts and tighten them to prevent loosening, which may lead to poor contact or open circuit.
Regular inspection and maintenance:
Regularly inspect and maintain the photovoltaic system, including the inspection and cleaning of components such as modules, brackets, inverters, and cables.
Timely identify and handle potential problems to ensure the long-term stable operation of photovoltaic systems.
Pay attention to lightning protection and grounding:
During installation, proper lightning protection and grounding measures should be taken to ensure the safe operation of the photovoltaic system.
In summary, when installing solar panels under different climatic conditions, it is necessary to select the appropriate installation Angle, materials and measures based on the local actual situation to ensure the long-term stable operation and efficient power generation of the photovoltaic system.
