What Is A PV Fixed Mounting Structure?

A fixed photovoltaic (PV) mounting structure is an essential component in solar panel systems, designed to hold solar arrays at a fixed angle to optimally receive sunlight. When designing these fixed PV mounting structures, key considerations include the local geographic, environmental, and climatic conditions to ensure the structure captures the maximum solar radiation. Once installed, the position of these structures typically does not require frequent adjustments.

Production Process

Mechanical Design

The mechanical design phase involves selecting suitable metal materials based on the terrain and climate conditions of the project site. The primary goal is to accurately design the structure of the PV mounting system to ensure it provides excellent stability. This ensures that the solar panel system can operate reliably for over 25 years, even in harsh environments. Well-designed PV mounting structures have robust wind and snow load resistance, as well as corrosion resistance. The design must balance product quality and cost-efficiency to meet customer needs effectively.

Mechanical Processing

The mechanical processing phase includes several key steps:

Column Processing:

Sawing: Cutting the workpiece according to the design specifications.

Punching: Creating holes in the workpiece as specified in the design.

Inspection: Checking the dimensions against design requirements.

Packaging: Packaging the processed parts according to standards.

Inventory: Storing the semifinished products in the inventory.

Main Beam Processing:

Welded Plate Connection: Ensuring smooth, continuous, and uniform weld seams.

Straightening: Feeding the head into the straightening roll and applying controlled force.

Forming: Using forming rollers to achieve the desired circular diameter.

High-Frequency Welding & Seam Trimming: Rapidly heating the steel strip edges with high-frequency current and extruding to weld.

Sizing: Compressing the rollers to achieve the required final dimensions.

Sawing and Drilling: Cutting and drilling holes as per design specifications.

Packaging and Inventory: Storing the processed parts in the inventory.

Purlin Processing:

Straightening: Using straightening machines to control the bending degree of steel coils.

Sawing and Welding: Cutting and welding the steel strip.

Punching: Using punch machines to create holes.

Roll Forming: Using a forming machine to shape the steel strip.

Hydraulic Shearing: Cutting the formed steel to size.

Packaging and Inventory: Automatic strapping and storing of semifinished products.

Welded Component Processing:

Sawing: Cutting the workpiece according to the required dimensions.

Stamping: Using a press and die to form the workpiece.

Cutting: Using cutting machines to achieve the desired size.

Laser and Plasma Cutting: Using high-density laser beams and high-temperature plasma arcs for cutting.

Inspection: Checking the welding machines and parts for proper setup.

Fixture Design: Designing welding fixtures for quality and efficiency.

Welding Programming: Programming the welding process based on component requirements.

Welding: Fixing components in welding fixtures and conducting welding.

Inspection: Inspecting the welded parts against design specifications.

Slag Removal: Cleaning the welded parts to remove slag.

Packaging and Inventory: Storing the processed parts in the inventory.

Galvanizing

The semifinished products from the mechanical processing stage undergo galvanizing to enhance their corrosion resistance.

Applications and Key Features of Fixed PV Mounting Structures

Fixed PV mounting structures are widely used in various solar power systems due to their simple construction and cost-effectiveness. They are particularly advantageous in the following scenarios:

Rooftop Solar Systems: These structures are ideal for rooftops with limited space and load capacity. Proper design allows efficient use of rooftop space, enhancing the power generation efficiency of the solar system.

Ground-Mounted Solar Plants: On open ground with strong foundation support and lower wind speeds, fixed mounting structures provide stability and safety. Optimized layout and design can increase both the efficiency and economic benefits of the solar power plant.

The widespread use of fixed PV mounting structures in the domestic solar market is due to their distinct advantages:

High Stability: Designed with robust structures, they maintain stability under various climatic conditions, ensuring the safe operation of solar panels.

Low Maintenance Cost: With no moving parts, these structures are simple and require minimal maintenance. Regular cleaning and inspection of solar panels are usually sufficient.

Easy Installation: The installation process is straightforward, requiring no complex calibration. Following the instructions or guidance from professionals enables quick and easy setup.

Wide Applicability: Suitable for various sites including rooftops, ground, and slopes, fixed mounting structures offer flexibility for urban and rural settings.

Long Lifespan: Typically, these structures have a lifespan exceeding 30 years, providing long-term reliability.

Conclusion

In conclusion, fixed PV mounting structures offer a reliable and cost-effective solution for maximizing solar energy capture. Their durability, ease of installation, and adaptability to various environments make them an attractive option for both residential and commercial solar projects. As the demand for solar energy continues to grow, investing in a fixed mounting system ensures long-term efficiency and sustainability, making it an excellent choice for potential buyers looking to harness the power of the sun effectively.
