Quick Answer
Solar tracking mounts are constructed using a variety of materials, including aluminum and steel alloys, which provide strength and durability. These materials are often used for the structure's frame, while other components such as gears and motors may be made from plastics and other synthetic materials. The choice of material depends on factors like weight, corrosion resistance, and cost.
Material Selection for Solar Tracker Frames
Aluminum alloys are a popular choice for solar tracker frames due to their high strength-to-weight ratio, corrosion resistance, and affordability. They are often used in the production of extruded profiles, which can be easily cut and assembled to form the frame’s structure. For example, 6061-T6 aluminum alloy is commonly used in solar tracker construction due to its excellent mechanical properties and resistance to corrosion.
Gearing and Motor Components
The gears and motors used in solar tracking systems are typically made from plastics and other synthetic materials, such as nylon and polyester. These materials are chosen for their low friction coefficients, high wear resistance, and ability to withstand the harsh outdoor environment. For example, 3D printing technology can be used to create complex gear shapes and structures, which can improve the efficiency and accuracy of the tracking system.
Corrosion Protection and Coatings
To protect the solar tracker’s components from corrosion, manufacturers often apply coatings and finishes to the frame and other metal components. These coatings can include anodizing, powder coating, and galvanizing, which provide a durable barrier against environmental factors like rain, snow, and salt. By selecting the right materials and coatings, solar tracker manufacturers can ensure the longevity and reliability of their products.
