A utility solar customer required anchors, profile parts and accessory hardware under a unified packing plan.

The stability and durability of a solar photovoltaic (PV) power generation system largely depend on the selection and installation of PV mounts and their accessories. PV mounting accessories, as the foundational components for connecting and supporting solar panels, are responsible for ensuring the safety and stability of the PV array while maximizing sunlight capture. Below is a detailed list of PV mounting accessories and their functions:

1. Main Mounting Components

C-channel/U-channel steel: Serving as the main frame of the mount, they have high load-bearing capacity and excellent mechanical properties, capable of adapting to various terrains and environmental conditions, providing the necessary support structure for the PV array.

2. Connectors

T-shaped angles: Widely used in centralized PV mounts and flat roof PV mount installations, they are used to connect different parts of the mount, ensuring the overall stability of the structure.

Angle brackets: Used to connect various parts of the PV mount, such as pillars and beams.

Connecting bolts, nuts, and washers: Ensure tight connections between all mount parts, preventing loosening due to vibration or wind, while also guaranteeing precise alignment during installation.

3. Rails and Beams

PV rails: Used to hold solar panels and ensure they receive sunlight at the optimal angle.

Beams: Support the rails and maintain the horizontal layout of the PV array.

4. Clamps and Fasteners

Mid clamps: Installed on both sides of the PV panels, securely fastening them to the rails, preventing sliding or movement.

End clamps: Located around the edges of the PV panels, providing lateral support to ensure the panels remain stable under wind pressure.

5. Fixing Accessories

Base: Used to anchor the entire PV mounting system to the ground or roof, ensuring a stable foundation.

Embedded parts: Pre-embedded in concrete foundations for later connection with the mount, providing strong anchoring.

Expansion bolts and anchors: Suitable for fixing on various substrates, such as concrete, steel structures, or wooden structures.

6. Other Auxiliary Accessories

Hooks: Used in specific types of PV mounting systems for hanging or securing components.

Thin-film clamps: Specifically designed for thin-film PV modules, providing specialized pressure distribution and securing methods.

7. Tracking System Accessories

Drive motors, transmission devices, and control systems: In tracking mount systems that follow the sun’s path, these accessories allow the PV array to move with the sun, maximizing sunlight utilization.

In summary, PV mounting accessories, as a complete system, work collaboratively to ensure the efficient operation and long-term stability of solar power plants. Selecting the appropriate PV mounting accessories and assembling them according to professional design and installation guidelines is critical for improving the economic efficiency of the power plant and extending its service life.
