3. Product Features

1. Anodized Aluminum Construction

Manufactured from aluminum alloy with anodized surface treatment for excellent corrosion resistance, oxidation resistance, and long-term outdoor durability.

2. U-Shaped Structural Design

The U-shaped channel structure provides a secure and stable connection between compatible solar mounting rail sections.

3. Solar Rail Extension

Designed to connect two separate mounting rails into a continuous rail structure, making it suitable for longer photovoltaic module arrays.

4. Elongated Slotted Holes

The slotted-hole design provides installation adjustment space and makes bolt positioning easier during assembly.

5. Accurate Rail Alignment

The splice connector helps maintain proper alignment between adjacent solar mounting rails at the connection point.

6. Lightweight and Durable

Aluminum alloy construction reduces component weight while providing reliable performance for photovoltaic mounting applications.

7. Easy Installation

The simple structure and adjustable mounting holes help reduce installation time and improve on-site assembly efficiency.

8. Customizable Design

Connector dimensions, material thickness, hole sizes, hole spacing, and compatible rail profiles can be customized according to specific project requirements.

4.Product Function

The Solar PV U-Shaped Rail Splice Connector is mainly used to join two sections of aluminum solar mounting rails.

During installation, the connector is positioned at the joint between two compatible rail sections. Matching bolts and fastening components are installed through the elongated slots to secure the connector and rails together.

The U-shaped structure provides additional positioning and support at the rail joint, while the elongated holes allow minor adjustment before final tightening.

This connection method extends the overall rail length while maintaining a stable and properly aligned mounting structure.

5. Applications

The Anodized Aluminum Solar PV U-Shaped Rail Splice Connector is suitable for a wide range of photovoltaic mounting systems, including:

● Residential rooftop solar mounting systems

● Commercial and industrial rooftop PV systems

● Metal roof solar mounting systems

● Flat roof photovoltaic systems

● Ground-mounted solar PV systems

● Solar carport mounting systems

● Large-scale photovoltaic projects

● Solar mounting rail extension

● Photovoltaic rail connection

6.Installation Method

Position the two solar mounting rail sections end to end.
Place the U-shaped rail splice connector at the rail joint.
Align the connector with the fixing positions of both rails.
Insert the matching bolts through the elongated mounting holes.
Adjust the connector and rail positions to ensure proper alignment.
Install the matching nuts or fastening components.
Tighten all fasteners securely according to the mounting system requirements.
Check that both rail sections are firmly connected and properly aligned.

7.Advantages of Anodized Aluminum

Anodized aluminum is widely used in photovoltaic mounting systems because it combines lightweight construction with excellent corrosion resistance and long service life.

The anodizing process forms a protective oxide layer on the aluminum surface, helping improve resistance to moisture, oxidation, and outdoor environmental exposure.

This makes the U-shaped rail splice connector suitable for long-term use in solar photovoltaic mounting structures.
