Mid Clamps for Solar Panels are specialized connectors used to secure the middle of the long edges of two adjacent photovoltaic modules. The core design utilizes a central clamping method to evenly distribute the module load to the rails and allows for limited displacement of the modules during thermal expansion and contraction, effectively preventing glass micro-cracks caused by stress concentration.

Features of Mid Clamps Solar Panels
Structural Design
Mid-clamp solar panels feature an arc or beveled design to reduce pressure concentration on the photovoltaic modules and prevent glass breakage.
Anti-slip and Wear-resistant
The bottom of mid-clamp solar panels is equipped with anti-slip serrations or rubber pads to increase friction and enhance stability.
Easy Installation and Disassembly
They support quick installation and disassembly, reducing construction difficulty and time costs.
Technical Service Support
Selection and Compatibility: Provides compatibility confirmation with mainstream rails and modules (feedback within 24 hours).
Design Collaboration: Provides 3D models and node drawings of the product, and can provide layout suggestions based on your load data.
Installation Support: Provides installation guidance and standard torque data, and has a dedicated channel to respond to on-site issues within 2 hours.
Certification Documents: Provides complete material and test reports with the shipment, and can assist in preparing documents required for international certifications (such as UL/TÜV).
FAQ
Q: What is the function of the middle cushioning pad?
A: To avoid hard contact between the metal and the module frame, cushion vibrations, prevent scratches, and allow for slight displacement due to thermal expansion and contraction.
Q: Is it compatible with all brands of photovoltaic modules and rails?
A: Not necessarily. The groove size of the lower clamp must precisely match the rail cross-section (such as C-type/U-type). Before purchasing, you need to confirm its compatibility with the rail brand, model, and module frame thickness used in your project. Sample testing may be required.
