The design and selection of solar panel mounting brackets in coastal areas must first consider the impact of typhoons. At the same time, it is also necessary to consider other natural factors such as humidity, severe salinization and corrosion, and high temperatures in the coastal areas.

To resist the damage of typhoons

The situation shown in the picture above can be inferred that the foundation of the mounting structure is too small. And the foundation is not effectively connected to the roof. Also, the height of the solar panel mounting systems is too high. The height of the two vertically placed modules is more than 4 meters, so the back side of the solar mounting brackets will subjected to a large wind pressure and easy to blow over.

To resist the damage of typhoons, first of all, a very strong solar panel fixing brackets is required. The general materials of solar panel racking system are aluminum alloy and carbon steel. Corigy can provide both type of those materials with different surface treatment. Theoretically, the maximum wind resistance of the solar mounting system solutions designed by Corigy can reach 216 km/h.

If it is installed on the roof, the foundation must be firm. The counterweight is generally a cement foundation. The cement foundation must fully consider the load of the building. At the same time, it must meet the requirements of wind load and snow load. Corigy's engineers team can help customers calculate the appropriate counterweight to avoid customers’ worries.

To resist the damage of moisture and salinization

Q235B steel or Aluminum Alloy materials have excellent corrosion resistance. For brackets in coastal areas we even use Q345B material.

In addition to the material, the thickness of the material and the thickness of the galvanized layer are also very important. Under normal circumstances, the thickness of the structure should not be less than 2.5 mm, the thickness of the galvanized layer should not be less than 65 microns. And the surface of the zinc layer should be evently, free of burrs, overburn, ash and scars and other defects. There must be no zinc tumors that affect the installation. The zinc layer of the thread should be smooth, and the bolt connection should be able to be screwed in. In addition, our new material, Al-Zn-Mg coating steel is becoming more and more popular as solar panel mounting structure in coastal areas.

To resist the damage of high temperatures

The temperature in coastal areas is generally higher, and the temperature has a great influence on photovoltaic modules。

Install the bracket a little higher, so that the bracket has a little bit away from the roof. So as to ensure ventilation and increase power generation. The installation location of the photovoltaic power station is also important. And it is necessary to consider the installation location, installation orientation, installation angle, load requirements, and arrangement and spacing.
