Varieties of Solar Mounting Systems

Aluminum Alloy Mounts

Aluminum alloy mounts are favored for their lightweight nature, aesthetic appeal, and durability, coupled with excellent corrosion resistance, making them ideal for applications with high load-bearing requirements such as rooftop installations. However, they have relatively lower load-bearing capacity, especially in terms of wind resistance and large-span applications, where they may not be as effective as steel. Additionally, aluminum alloy mounts are more expensive, with prices approximately three times that of steel.

Galvanized Steel Mounts

Galvanized steel mounts are widely used due to their stable performance, high load-bearing capacity, and ease of installation. They undergo a hot-dip galvanizing process, which provides excellent corrosion resistance and lower costs, making them suitable for large-scale projects. However, in high humidity or high salinity environments, their corrosion resistance is inferior, necessitating thicker galvanization layers and regular maintenance. Moreover, their recycling value is relatively low compared to other materials.

Stainless Steel Mounts

Stainless steel mounts are renowned for their extreme corrosion resistance and high strength, maintaining performance even in extreme environments, making them suitable for applications requiring substantial load-bearing capabilities. However, the high cost of stainless steel mounts may limit their use in cost-sensitive projects.

Non-metallic Mounts (e.g., Fiber Composite Materials)

Non-metallic mounts, such as fiber composite material mounts, are gaining attention for their light weight and good mechanical properties, capable of withstanding certain loads and facilitating ease of installation and transportation. As a relatively new material, their long-term performance and reliability require further validation through practical projects. Compared to traditional metal mounts, their cost-effectiveness is yet to be clearly defined.
