An aluminum die casting photovoltaic bracket disc is a structural component used in solar mounting systems. It is typically installed as a connection or load-bearing node within a photovoltaic bracket assembly, helping to secure solar panels and maintain mechanical stability under various working conditions.

Basic Definition and Structure

In a photovoltaic mounting system, brackets are responsible for supporting solar modules and transferring loads to the foundation or roof structure. The bracket disc, manufactured through aluminum die casting, functions as a key connecting element between support arms, base plates, or adjustable joints.

The die casting process involves injecting molten aluminum alloy into a precision mold under high pressure. This method produces parts with consistent dimensions, detailed geometry, and good surface finish. As a result, the photovoltaic bracket disc can meet the dimensional tolerance and structural strength requirements of solar mounting applications.

Why Aluminum Die Casting Is Used

Aluminum alloys are widely applied in photovoltaic support systems due to their favorable strength-to-weight ratio and corrosion resistance. Compared with traditional steel components, aluminum die cast parts are lighter, which simplifies transportation and on-site installation.

Die casting also enables the integration of complex features—such as threaded holes, reinforcing ribs, and positioning slots—into a single component. This reduces the need for secondary machining and improves assembly efficiency. For large-scale solar projects, standardized die cast discs contribute to consistent quality control across batches.

Functional Role in Photovoltaic Systems

The photovoltaic bracket disc typically performs one or more of the following functions:

Load Distribution – It helps distribute wind, snow, and dead loads from the solar module to the supporting structure.

Connection and Alignment – It connects multiple bracket elements and ensures proper alignment during installation.

Adjustability Support – In adjustable mounting systems, the disc may serve as a pivot or rotation interface to optimize panel tilt angles.

Because photovoltaic installations are exposed to outdoor conditions for extended periods, the disc must maintain structural integrity over time. Surface treatments such as anodizing or powder coating are often applied to enhance durability and resistance to oxidation.

Application Scenarios

Aluminum die casting photovoltaic bracket discs are commonly used in:

Rooftop solar mounting systems

Ground-mounted solar farms

Carport photovoltaic structures

Industrial and commercial solar projects

Each application may require different specifications in terms of thickness, diameter, and load capacity. Therefore, customization based on project design drawings is common in manufacturing.

Conclusion

An aluminum die casting photovoltaic bracket disc is a precision structural part used in solar mounting systems to provide connection, support, and load transfer functions. Manufactured through high-pressure die casting, it offers dimensional consistency, structural reliability, and installation efficiency. As photovoltaic projects continue to expand in scale and complexity, such components play a critical role in ensuring stable and secure mounting system performance.
