In solar plant construction, selecting the appropriate support structure is crucial. This article provides a detailed comparison of the single-layer cable suspension structure and the double-layer cable truss structure in flexible solar mounting system, outlining their characteristics, advantages, applicable conditions, and usage scenarios to help you choose the most suitable support system for your specific project.

Flexible Single-layer Cable Suspension Structure

The single-layer cable suspension structure consists mainly of a primary steel frame made up of beams and columns, along with diagonal cables and main cables. The cables run parallel to the PV module plane, forming a self-balancing system through tensioning equipment.

• Load-Bearing Characteristics: This structure is simple and has a single force-bearing mode. By tensioning the module-supporting cables, it gains stress stiffness, thus forming a stable self-balancing system.
• Advantages: Simple structure, low steel consumption, relatively low cost, strong adaptability to terrain, high pre-assembly capability, and significantly reduced construction time.
• Applicable Conditions: The typical span of a single-layer flexible cable mounting system ranges from 15m to 20m, with a maximum reach of 30m.
• Usage Scenarios: Suitable for relatively flat terrain with moderate span and height requirements.

Flexible Double-layer Cable Truss Structure

Building upon the single-layer cable suspension structure, the double-layer cable truss structure adds load-bearing cables and rigid struts, forming a more complex structural system.

• Load-Bearing Characteristics: As a semi-rigid structure, it has a clear force transmission mode. By tensioning the double-layer cables, it gains stress stiffness and forms an independent wind-resistant system, enhancing structural stability.
• Advantages: The double-layer structure allows for larger spans and greater stability, making it particularly suitable for use in high-wind environments. Although the initial investment may be higher, its superior wind resistance and long-term stability offer better cost-effectiveness.
• Applicable Conditions: The typical span of a double-layer flexible cable structure system ranges from 30m to 50m, with a maximum reach of 60m.
• Usage Scenarios: Suitable for complex terrains, high-wind conditions, and projects requiring large spans and high clearance.

When selecting between single-layer and double-layer flexible structures, it is essential to consider factors such as geographical and climatic conditions, the expected scale of the solar mounting system, and budget constraints.Single-layer structures are ideal for projects that do not require large-span structures. Double-layer structures are better suited for projects that demand high stability and strong wind resistance. Before making a final decision, conducting a detailed site evaluation and cost-benefit analysis is recommended to ensure that the chosen structure type meets your specific project requirements.
