End Clamps

The End Clamps of Egret Solar , like the middle pressure block, needs to be compatible with the thickness of the component frame (usually 30-40mm), It can be Customized according to different engineering solutions,and it is made of anodized aluminum alloy material to avoid corrosion with the component frame and play an insulating role at the same time.

Key Features

end clamp solar fixes the frame of the outermost component of each row to the end of the rail to prevent it from slipping off. At the same time, pressing the edges of the components helps to reduce the invasion of wind, rain and dust from the sides.It is located at the edge of the array and directly bears the strongest wind lifting force (upward pulling force) and wind suction force,It is a key force-bearing point in the wind-resistant design and must have sufficient mechanical strength.

The difference between Solar clamp

The installation position of the end clamp for solar panels is at the beginning and end of the array, and only the outer frame of one module is fixed. Its core force mainly bears the strongest edge wind load from one side of the module, and at the same time plays the role of terminal fixation, resisting extreme wind pressure, and sealing the edge. The appearance is usually designed with one end closed or featuring an end cover.

The Mid Clamp is installed in the middle of the array and clamps the inner frames of two adjacent components simultaneously, bearing the force transmitted by the two adjacent components. It mainly resists the upward wind lifting force. Both ends of the Mid Clamp are open and are used to hold the panel.

Design Principles

The design of the product solves the key problems that are often encountered in practical engineering,The traditional end pressure block is prone to rotation and displacement when tightened, the Egret Solar designs of the end clamps for solar panel mounting three-angle bearing surface designed, developed and produced converts the rotational force generated by fastening into a vertical downward locking force through a unique contact surface, fundamentally solving this problem and making the installation more firm, The T-bolt design with anti-slip teeth The bolts can be clamped in the guide rail grooves for fixation, making one-handed operation possible and greatly enhancing the convenience of installation.

People also ask

Q: Why must it come from the same brand or compatible series as the guide rails and components? Can they be used randomly?

A: It is not recommended to mix them. Due to mechanical mismatch, the groove width and shape tolerance of profiles (guide rails) of different brands are different. The solar panel end clamps

or T-bolt may not be correctly inserted or locked, resulting in an unstable installation.

Q: During installation, the bolts keep spinning and can't be tightened. What should I do?

A: It might be caused by improper installation sequence or tools. First, make sure the bolt head is correctly inserted into the guide rail groove. Secondly, a torque wrench must be used and the tightening should be carried out in accordance with the torque value specified in the product manual (usually within the range of 16 to 20 Newton-meters). First, initially tighten it by hand, and then finally tighten it with a torque wrench.

Q: What are the special requirements for the selection of materials for products in snowy and cold regions?

A: It is recommended to use aluminum alloy as the main material. The surface is treated with anodize oxidation to provide a good protective layer and prevent corrosion.
