End Clamp for Solar Panels WattPower PV-KK/35-50/B — 35 mm

End clamp WattPower PV-KK/35-50/B — 35 mm is a mounting accessory designed to secure the outer edges of framed photovoltaic modules in rooftop and ground‑mounted solar arrays. The clamp fits module frame thicknesses within the specified range, applies consistent clamping pressure, and installs directly onto standard mounting rails. Its corrosion‑resistant finish and compact profile make it suitable for long‑term outdoor exposure and integration with typical residential and commercial PV racking systems.

Advantages

The WattPower end clamp offers precise edge retention with a low-profile design that minimizes shading and wind loads on the module edge. Manufactured for reliable mechanical contact, the clamp delivers consistent clamping force and stable positioning of the solar panel. Its surface treatment increases resistance to atmospheric corrosion, reducing maintenance needs in outdoor installations. Installation is straightforward: the component aligns to the rail and secures the panel without complex adjustments.

Suitable for

• Securing outer edges of framed photovoltaic modules on rooftop systems
• Ground-mounted solar arrays with compatible rail systems
• Residential and small commercial PV installations
• Retrofit projects where low-profile clamps are required

Key specifications

• Designed for module frame thickness compatible with a 35 mm clamping range
• Low-profile clamp head to reduce shading and wind exposure
• Corrosion-resistant surface treatment suitable for outdoor use
• Compatible with standard PV mounting rails for slide-in or bolt-on attachment
• Mechanical clamping that provides stable module fixation without penetrating the panel frame

How to use

Position the WattPower end clamp at the module edge on the mounting rail so the clamp jaw aligns with the panel frame. Engage the clamp with the rail slot and adjust the position to ensure even contact along the frame edge. Tighten the fastening screw or bolt to the manufacturer’s recommended torque to achieve secure clamping pressure while avoiding over‑compression of the frame. Verify module alignment and gap dimensions along the row before completing adjacent clamps. Perform torque checks after initial thermal cycling to confirm retention.

Usage recommendations

Use appropriate stainless or galvanised fasteners compatible with your rail system and follow local installation standards. Inspect clamps periodically for corrosion or loosening, especially after severe weather. Avoid overtightening to prevent damage to the module frame and follow the panel manufacturer’s guidance for permitted clamping points and torque limits.
