W shaped aluminum ground solar mounting structure

Product Introduction

The W-Type Aluminum Ground Mounting System is specifically designed for large-scale ground power stations and industrial & commercial distributed projects. Its name derives from the stable "W"-shaped bionic structure formed at the connection between the post and the rail. This design achieves the perfect balance of lightweight construction and corrosion resistance while ensuring ultra-high load-bearing capacity. Highly pre-assembled, this system is suitable for sandy soil, gravel, hard soil, and concrete foundations, making it an ideal solution for complex terrains.

Why Choose the W-Type Structure?

Compared with traditional aluminum or steel mounting structures, the W-type design significantly improves structural strength while reducing material consumption. The closed or semi-closed cavity profile not only provides a clean appearance but also effectively reduces wind resistance and protects the back of PV modules from turbulent airflow caused by strong winds.

Key Advantages

1. Extreme Environmental Adaptability

Superior Wind Resistance: Passed rigorous wind tunnel tests; can withstand wind speeds up to 60 m/s (approx. 216 km/h) , equivalent to a Category 17 hurricane.

High Snow Load Capacity: Supports snow loads of up to 1.4 KN/m², ensuring stability in high-latitude, cold regions.

Excellent Corrosion Resistance: Made of AL6005-T5 aluminum alloy (anodized) and SUS304 stainless steel fasteners. Exceptional resistance to salt spray corrosion, especially suitable for coastal tidal flats and high-humidity areas.

2. Efficient Installation Experience

Highly Pre-assembled: Key connectors are pre-assembled with the rails at the factory. No complex cutting or welding is required on-site; simple tools are enough for fixing, saving approximately 50% of installation time.

Flexible Adjustability: Pre-set adjustment holes on the rails allow free tilt angle adjustment from 0° to 60°, maximizing irradiation absorption based on the project's latitude.

3. Universal Compatibility

Panel Agnostic: Compatible with all conventional framed modules and some frameless modules.

Bi-directional Layout: Supports both landscape and portrait panel orientations, allowing flexible array design for power stations.
