Product Overview
The SC-Solid Series Solid Mid Clamp is a critical component in solar mounting systems, specifically designed for securing and clamping photovoltaic modules. Featuring a solid, one-piece structure, it works in tandem with mounting rails to firmly fasten module frames, effectively resisting harsh environmental conditions such as strong winds and heavy snow loads. Renowned for its exceptional strength, corrosion resistance, and installation convenience, this product is a reliable choice for ensuring the long-term stability and performance of PV arrays.
Key Features & Advantages
High-Strength Solid Structure
Manufactured from high-strength aluminum alloy (e.g., 6005-T5) via precision extrusion and heat treatment, ensuring a robust construction with no weak points.
The solid design offers superior compressive and shear strength, effectively withstanding stresses from thermal expansion/contraction and external loads, preventing module movement or loosening even under strong winds.
Exceptional Corrosion Resistance
Made from corrosion-resistant aluminum alloy and finished with high-quality anodization.
The anodized layer significantly enhances weatherability, UV resistance, and chemical corrosion resistance, making it suitable for harsh environments like coastal areas, and ensuring a service life commensurate with the PV system.
Universal Compatibility & Flexibility
Its thoughtfully engineered profile accommodates the frame edges of most PV module brands and models on the market (typically compatible with 30-50mm frame heights).
Perfectly matches various standard C-shaped or U-shaped rails, offering great flexibility for system design.
Easy and Efficient Installation
No special tools required; easy fixation using standard hex head bolts or T-bolts.
The simple one-piece design reduces part count, minimizes installation complexity, and significantly improves efficiency, saving on labor costs.
Secure and Reliable Clamping Force
The large, flat contact surfaces with the module frame and rail provide a uniform and powerful clamping force.
Ensures firm module retention while avoiding potential damage to the module glass or frame caused by excessive point pressure.

Solid Mid Clamp, 40 x 40 mm
-
Place Modules: Position the PV modules on the installed rails.
-
Position Mid Clamp: Place the solid mid clamp between the frames of two adjacent modules, engaging it with the rail.
-
Insert Bolt: Insert the T-bolt or standard bolt through the rail slot and into the clamp's installation hole.
-
Finger Tighten: Hand-tighten the accompanying lock nut until the clamp contacts the module frames.
-
Final Torque: Using a torque wrench, tighten all mid clamps evenly to the specified torque value (e.g., 14 N·m).
Note: Always follow the complete installation manual provided by the supplier and use the correct installation torque to avoid module damage or installation failure.
