A ground-mounted slotted C-section steel photovoltaic system with landscape (horizontal) module orientation represents a highly engineered, versatile solar racking solution for utility-scale and commercial solar projects. This system combines the structural efficiency of cold-formed C-section steel profiles with integrated slotting features that enable rapid, tool-free assembly and precise module positioning, while the landscape orientation of modules maximizes wind load distribution and array stability.

Core Structural Component: Slotted C-Section Steel Design

Distinctive Profile Geometry: The system utilizes cold-formed C-section steel profiles engineered for maximum structural efficiency. The C-shaped cross-section features inwardly curled flanges that provide:

• Enhanced torsional stiffness compared to plain channel sections

• Smooth, safe edges for handling during installation

• Integrated mounting surfaces for accessory attachment

Axial Stiffening Ribs : A key design innovation is the incorporation of longitudinal stiffening ribs along the web of the C-channel. These ribs:

• Increase bending resistance by up to 30% compared to plain sections

• Prevent local buckling under high compression loads

• Maintain sectional stability during extreme wind events

Auxiliary Calibration Markings : Side surfaces are embossed with graduated scale markings (typically at 10mm or 20mm intervals) that

• Enable precise on-site cutting without separate measurement tools

• Ensure consistent component preparation across multiple installers

• Reduce measurement errors during fabrication

• Speed up installation by eliminating separate layout steps
