Key Installation & Usage Precautions

- Confirm Panel Frame Thickness Before Installation: Verify the actual thickness of on-site solar panel frames in advance, select the corresponding adjustable gear of the end clamp, avoid excessive clamping gap leading to loose fixation, or excessive clamping force causing frame extrusion and hidden crack damage.

- Ensure Serrated Clamping Surface Fits Closely: During installation, keep the serrated anti-slip surface fully fitted with the solar panel edge frame, no offset or tilting, to give full play to the friction anti-slip performance and ensure stable edge locking effect.

- Standardize Locking Torque to Avoid Structural Damage: Control uniform and moderate tightening torque during construction. Excessive force will deform the clamp body or crush the aluminum frame; insufficient force will reduce wind resistance and cause component displacement in strong wind weather.

- Unified Horizontal Installation of Edge Clamps: All end clamps on the outer edge of the PV array shall be installed horizontally at the same level, avoiding height difference stress concentration, to ensure the overall uniform stress and consistent wind resistance of the entire solar array.

- Check Accessory Integrity Before Construction: Confirm that the matching bolts, gaskets and other accessories are complete and intact, no missing or damaged parts, to avoid virtual installation and affect the long-term stability of the system.

- Full Inspection After Batch Construction: After completing batch installation, conduct a comprehensive inspection of all end clamp locking status, check for looseness, offset and untightening problems, and eliminate potential safety hazards for long-term outdoor operation.
