AA-C40 Solar Rail Clamp – Aluminum PV Mounting Accessory

1. Product Overview

The AA-C40 Solar Rail Clamp is an aluminum mounting accessory developed for compatible photovoltaic rail mounting configurations.

Manufactured using AL6005-T5 aluminum alloy and SUS304 stainless steel fastening components, this product is designed to provide a mechanical clamping and fastening connection within a solar mounting assembly.

In a photovoltaic mounting system, rail clamps and connecting components play an important role in securing structural elements and maintaining the intended mounting configuration.

The AA-C40 features a compact metal clamping structure with a bolted fastening arrangement. Its design is intended for integration with compatible mounting components, subject to verification of the actual rail profile and connection dimensions.

As a solar mounting system manufacturer, ALV provides aluminum mounting accessories and customized photovoltaic structural solutions for international project customers.

2. AA-C40 Solar Rail Clamp Specifications

For accurate product selection, customers are encouraged to request the latest technical drawing, overall dimensions, material specifications, fastening details and compatible rail information.

3. Key Features of the Aluminum Solar Rail Clamp

AL6005-T5 Aluminum Alloy Construction

The main aluminum component of the AA-C40 is manufactured using AL6005-T5 aluminum alloy.

The 6005 alloy belongs to the 6xxx series of aluminum alloys, which are widely used in extruded structural components.

According to Hydro’s technical information, 6005 aluminum offers a useful combination of mechanical properties and extrusion characteristics. The T5 temper provides specified mechanical properties through artificial aging.

This makes the alloy a relevant material option for aluminum components used in photovoltaic mounting structures.

Hydro – Aluminum 6005 Alloy Properties.

Actual mechanical properties should be verified against the supplied material certificate and applicable product specifications.

SUS304 Stainless Steel Fasteners

The AA-C40 uses SUS304 stainless steel fastening components.

Stainless steel fasteners are commonly selected for outdoor mechanical assemblies because of their corrosion resistance and suitability for many general industrial environments.

For photovoltaic applications, the fastening components must be compatible with the aluminum mounting parts and the environmental conditions at the installation site.

Particular attention should be given to coastal projects and locations with high humidity or airborne salt.

Compact Mechanical Clamping Structure

The AA-C40 features a compact aluminum clamping body combined with a bolted fastening arrangement.

Its structure is intended to provide a mechanical connection between compatible mounting components.

For system designers and installers, selecting the correct clamp geometry is important. The contact surfaces, bolt arrangement and rail engagement must match the actual mounting configuration.

Before ordering, customers should provide the corresponding rail cross-section or assembly drawing so ALV can check compatibility.

Suitable for Photovoltaic Mounting Assemblies

Solar mounting systems contain multiple interconnected structural components, including rails, clamps, brackets, connectors and fasteners.

Each component must work with the overall mounting design to maintain mechanical stability.

The AA-C40 is offered as part of ALV’s photovoltaic mounting accessory range, supporting customers who require aluminum components and fastening solutions for solar mounting projects.

4. Material Compatibility and Corrosion Considerations

Photovoltaic mounting systems are generally exposed to outdoor conditions for extended periods.

Rain, humidity, temperature fluctuations, industrial pollution and airborne salt can influence the corrosion behavior of metal components.

When aluminum and stainless steel are used together, the complete assembly should be evaluated for galvanic corrosion risks.

The U.S. Department of Energy explains that dissimilar metals in electrical contact in the presence of moisture can experience galvanic corrosion.

This is particularly relevant to photovoltaic installations in coastal and marine environments.

For additional technical guidance, refer to:

U.S. Department of Energy – Managing and Mitigating Solar PV Corrosion.

Appropriate material selection, surface treatment, isolation measures and drainage design should be considered according to the installation environment.

5. Installation and Compatibility Considerations

Correct component selection is essential for the reliability of photovoltaic mounting structures.

Before installing the AA-C40 Solar Rail Clamp, the following points should be verified:

• Confirm the dimensions and cross-section of the mating rail.
• Check the clamp’s engagement and contact surfaces.
• Verify the bolt diameter, thread and effective fastening length.
• Confirm the compatibility of the aluminum and stainless steel components.
• Follow the approved installation instructions and specified tightening torque.
• Check that the completed connection meets the structural design requirements.

The tightening torque should not be assumed from another clamp model. It must be confirmed using the approved AA-C40 technical documentation.

For photovoltaic mounting system certification and electrical bonding requirements, refer to:

UL Solutions – PV Mounting Systems Certification.

UL 2703 covers photovoltaic mounting systems, mounting devices, clamping and retention devices, and grounding components. However, this does not mean that the AA-C40 itself is UL 2703 certified.

6. Applications in Solar Mounting Projects

The AA-C40 is intended for compatible photovoltaic mounting configurations where its clamp geometry and fastening arrangement match the system design.

Potential project discussions include:

• Residential rooftop solar mounting systems.
• Commercial and industrial photovoltaic installations.
• Ground-mounted solar structures.
• Aluminum rail mounting assemblies.
• Customized photovoltaic mounting solutions.

Final application suitability depends on the actual mounting arrangement, structural loads, rail dimensions, installation conditions and engineering approval.

For high-wind, heavy-snow or coastal projects, the complete mounting assembly should be evaluated according to the applicable project design standards.
