Solar Photovoltaic (PV) Mounting System Components and Functions
Primary Support Structure
Vertical Columns (Support Posts)Function: Vertical load-bearing core transmitting structural loads to the foundation.Types: Single-column (lightweight design), Dual-column (enhanced wind resistance).Materials: Hot-dip galvanized steel (thickness ≥2.75mm, zinc coating ≥80μm) or aluminum alloy (lightweight, ideal for distributed projects).
Beams & RailsFunction: Horizontal support for modules, ensuring spacing adjustment and alignment precision.Design: C/U-shaped aluminum alloy rails (anodized surface treatment), compatible with standard module dimensions (e.g., 2.1-meter rails for 72-cell modules).
Braces & ConnectorsFunction: Reinforce lateral force resistance (wind/snow loads).Types: Diagonal braces (triangular reinforcement), horizontal tie rods.Materials: Hot-dip galvanized steel bolts with anti-loosening treatment.
