Product Overview & OEM/ODM Capabilities
The Xiamen Bristar adjustable solar panel clamp is designed to secure framed PV modules ranging from 30mm to 35mm in height. By utilizing a dual-compatibility sliding mechanism, this single component functions as both a mid clamp and an end clamp across varying panel depths. This versatility reduces on-site inventory requirements and simplifies structural planning for EPC contractors.
As an established China factory, we provide extensive OEM/ODM manufacturing services. Our in-house engineering team delivers CAD modeling, finite element analysis (FEA), and custom extrusion die development to match specific mounting rail geometries. We accommodate requests for custom anodization thicknesses, specialized packaging, and custom bolt lengths to meet diverse project specifications.

Quality Control & Testing Standards
Our manufacturing facility employs strict quality assurance protocols to guarantee long-term mechanical reliability. Raw material batches of AL6005-T5 undergo optical emission spectrometry to verify aluminum-magnesium-silicon alloy proportions. Every production run is subjected to rigorous pull-out and shear-strength testing on our hydraulic tensile equipment to ensure clamp grip security under simulated wind loads.
Surface treatment quality is verified via 240-hour salt spray testing (ASTM B117) to confirm the integrity of the anodized layer against industrial atmospheric pollutants and coastal marine environments. In addition, fasteners undergo torque limits testing to prevent thread stripping during high-speed impact-driver installation on-site.
Typical Application Scenarios
The structural adaptability of our solar roof clamp makes it suitable for multiple array configurations:
1.Commercial rooftop PV plants: Secures commercial-grade 182mm and 210mm modules onto aluminum trapezoidal sheet roof rails.
2.Commercial rooftop PV plants: Secures commercial-grade 182mm and 210mm modules onto aluminum trapezoidal sheet roof rails.
3.Utility-scale solar farms: Provides rapid-mounting solutions on ground-mount aluminum racking structures to accelerate installation schedules.
FAQ
Q: How does the adjustable design of the mid and end clamp maintain structural integrity under wind loads of 60m/s?
A: The engineered interlocking groove system on the AL6005-T5 clamp body locks firmly with the rail under tension. Together with high-tensile SUS304 bolts torque-tightened to 15m, this design prevents panel slippage and frame distortion, matching AS/NZS 1170.2 standards up to 60m/s
Q: Does this solar roof clamp support direct grounding for electrical safety across different module frame anodization depths?
A: Yes. The integrated grounding pins pierce the anodized surface of both the 30mm and 35mm module frames during tightening. This creates a continuous, low-resistance electrical path back to the copper ground wire, complying with UL 467 safety standards for electrical bonding.
Q: What is the lead time and packaging configuration for wholesale container orders shipped from your China factory?
A: We deliver standard bulk orders within 10 to 15 days from our Xiamen facility. Clamps are pre-assembled and packed in high-density, double-corrugated export cartons (800 pieces per carton) and securely palletized to guarantee zero mechanical damage during maritime transit.
