Understanding Photovoltaic Bracket Board Thickness

When designing solar mounting systems, the thickness of the bracket board is critical for stability and durability. But how thick is the board for a photovoltaic bracket? Let's break it down with industry-specific insights and real-world examples.

Key Factors Influencing Board Thickness

• Material type: Aluminum (3-5 mm) or galvanized steel (2.5-4 mm) are common.
• Wind/snow loads: Coastal areas may require 20% thicker boards than inland regions.
• Panel weight: Modern 500W panels need 3.2-4.5 mm supports versus 2.8 mm for older 300W models.

Industry Trends Shaping Bracket Design

The solar sector now embraces lightweight reinforcement through ribbed designs, allowing 10-15% material reduction without compromising strength. For instance, a 3.2 mm corrugated steel bracket now matches the load capacity of traditional 4 mm flat plates.

Case Study: Desert Solar Farm

A 50MW project in Nevada used 4.2 mm aluminum brackets with nano-coating protection. After 5 years of sandstorms and 110°F heat:

• Zero structural deformation
• Corrosion rate 60% lower than standard coatings
