Mounting Profile for Solar Panels Extralink USP-SM-1100 – Aluminum Rail for Photovoltaic Panel Installation

Extralink USP-SM-1100 is an aluminum mounting profile engineered for photovoltaic panel installation. The rail functions as a primary structural element for securing solar modules to roof-mounted or ground-mounted systems, providing a stable base for panel clamps, bolts and other fasteners. Designed for compatibility with standard PV module frames, this mounting profile supports alignment, load distribution and straightforward attachment in residential and commercial arrays.

Advantages

The aluminum construction offers corrosion resistance and a favorable strength-to-weight ratio, which simplifies handling and reduces additional structural load. Its extruded profile ensures consistent cross-section and straightness, facilitating repeatable alignment during installation. The rail provides secure anchoring points for clamps and fasteners and is compatible with commonly used PV mounting components, supporting efficient assembly and reliable module fixation.

Suitable for

• Roof-mounted photovoltaic systems on pitched and flat roofs
• Ground-mounted solar arrays where aluminum rails are specified
• Residential and commercial solar panel installations
• Retrofit and new-build PV projects using framed modules

Key specifications

• Material: aluminum alloy suitable for outdoor structural use
• Profile type: extruded rail designed for panel clamp attachment
• Surface: corrosion-resistant finish appropriate for exterior exposure
• Compatibility: supports standard framed photovoltaic modules and common clamp systems
• Function: structural support for alignment, load distribution and fastening of modules

How to use

Position and fix the aluminum rail onto the roof structure or mounting substructure according to the project layout and local wind and snow load requirements. Ensure rails are aligned and leveled before securing with appropriate anchors or brackets. Attach photovoltaic modules using compatible clamps and fasteners, following the clamp manufacturer's torque specifications and the module supplier's installation instructions. Maintain recommended spacing between rails and modules to allow for thermal expansion and drainage.

Usage recommendations

Confirm material compatibility and load ratings with the overall mounting system; use corrosion-resistant fasteners and apply correct torque values. Inspect alignment and fastening points during and after installation and follow local building codes and PV installation standards for safe, long-term performance.
