Types of Aluminum Mounting Structures for Solar Power Plants

Aluminum mounting structures used in solar power plants vary in design depending on the shape of the support legs. These structural differences directly affect the strength and application of each type. Understanding these variations allows EPCs, investors, and project owners to make informed decisions in collaboration with manufacturers and installers.

Common Aluminum Frame Types

W-Type Structure: High Strength and Stability

The W-type mounting structure features a dual-rail configuration extending from the legs to the vertical support beams, forming a “W” shape. This design includes multiple reinforcement points, making it one of the strongest types. It is frequently used in regions with high wind or snow loads.

N-Type Structure: Balanced Strength and Cost

This configuration consists of a horizontal rail between the vertical legs, resembling the letter “N.” While not as robust as the W-type, it offers sufficient strength for moderate environments and is widely adopted for its cost-efficiency.

A-Type Structure: Low-Height Solutions

The A-type features a diagonal rail extending from one leg to a beam, creating a triangular “A” profile. When installed on screw piles, this configuration results in relatively low panel height, which may affect clearance and shading. However, with a concrete foundation, the height can be adjusted appropriately.

This type is ideal for flat, open fields where minimal elevation is acceptable and concrete piers can be utilized.

Key Takeaways for Project Owners

• Design Choice Impacts Safety: Each frame type offers distinct mechanical strength and durability. W-type is optimal for heavy-duty use, N-type balances cost and performance, and A-type is suited for low-profile installations.
• Foundation Matters: Whether using screw piles or concrete blocks, matching the right frame type with the right base ensures structural integrity.
• Informed Decisions Lead to Safer Plants: Understanding basic frame configurations helps you ask the right questions during vendor discussions and ensure the most appropriate system is selected.

For example, in Japan, where typhoons and heavy snowfall are common, W-type structures on screw piles are favored for their enhanced rigidity. However, in dry inland regions, a lighter N-type on concrete blocks may suffice.
