Solar panel mounting clamp

Product Details

Solar panel mounting clamps connect photovoltaic modules to aluminum mounting rails, providing mechanical fastening for rooftop and ground-mounted PV installations. Bristar manufactures aluminum mid clamps and end clamps using AL6005-T5 aluminum alloy, with SUS304 stainless steel bolts and fastening components available for outdoor applications.

The mid clamp secures two adjacent solar panels, while the end clamp fixes the outer edge of the module array. Different clamp heights and profiles are available to accommodate common photovoltaic module frame dimensions, including 30 mm, 35 mm, 40 mm and 45 mm.
The clamp assembly can be supplied separately or integrated with aluminum rails, roof brackets, bolts and other PV mounting accessories.

Technical Specifications & Materials

The following table provides the main technical configuration options. Final dimensions and mechanical specifications should be confirmed against the selected PV module and mounting rail.

Material Selection

AL6005-T5 aluminum alloy is used for its mechanical strength, relatively low weight and outdoor corrosion resistance. Anodized surfaces provide an additional protective oxide layer for exposed mounting components.

SUS304 stainless steel bolts and nuts are available for mechanical fastening. Material selection should consider the installation environment, exposure to moisture, coastal conditions and contact between dissimilar metals.
 

Quality Control & Testing Standards

Bristar maintains an independent quality inspection process covering incoming materials, machining operations, assembly and finished-product inspection.

Each production batch undergoes dimensional checks before entering the finished-goods warehouse. Inspection items include:

Clamp height, width and overall dimensions.

Bolt-hole position and machining accuracy.

Aluminum surface condition and anodizing quality.

Thread condition and fastener compatibility.

Contact between the clamp and module frame.

Assembly fit with the specified mounting rail.

Fastening performance and mechanical load verification.

Material certificates and third-party inspection arrangements can be provided according to project requirements.

For customers requiring additional verification, Bristar supports third-party inspections, material composition analysis, tensile testing and mechanical performance testing through agreed inspection procedures.

Relevant CE documentation and ISO 9001 quality management information can be supplied where applicable to the product and order.

Products that fail inspection are separated from approved stock and cannot enter the normal shipping process. Inspection records are retained for batch traceability.

This process helps reduce dimensional deviations, assembly problems and inconsistent product quality in large-volume PV mounting projects.

Packaging & International Shipping

Solar panel mounting clamps contain machined aluminum surfaces, threaded connections and fastening components that require proper protection during international transportation.

Bristar uses product-specific packaging arrangements based on clamp dimensions, order quantities and shipping methods.

Typical packaging measures include:

• Separate packing of different clamp specifications.
• Protective packaging to reduce surface scratches.
• Carton packing to prevent movement during handling.
• Moisture-resistant inner packaging where required.
• Clear product labels and quantity identification.
• Palletizing for bulk export orders when specified.

For container shipments, cartons and pallets are arranged according to container dimensions, cargo weight and loading requirements. Finished-product quantities are checked against packing lists before dispatch.

Customers can request packaging photographs, loading records and shipment documentation before container departure.

Our Core Advantages

1. Direct Factory Manufacturing

Bristar manages product manufacturing and export supply through its own production facility. Direct factory supply reduces additional trading links and allows customers to communicate with the production team about specifications, quantities and delivery arrangements.

2. Competitive Manufacturing Costs

In-house processing and coordinated production help control machining costs, material utilization and order handling expenses. Wholesale quotations are calculated according to material grade, dimensions, surface treatment and order quantity.

3. Multiple Production Lines

Parallel production arrangements support different clamp specifications and batch orders. This helps reduce dependence on a single production line and provides greater flexibility for repeat purchasing.

4. Custom Engineering Support

Customers can submit drawings, samples or module specifications for technical review. Custom dimensions, bolt configurations and rail interfaces can be evaluated before mass production.

5. Integrated PV Mounting Supply

In addition to clamps, Bristar manufactures aluminum rails, roof brackets, ground mounting components, solar carport structures and related accessories. Customers can source multiple mounting components through one manufacturing supplier.

Customer Factory Visit & Technical Discussion

Bristar welcomes customers from around the world to visit our factory, inspect production facilities and review manufacturing processes.
