🔹 What is an Aluminium Long Rail Solar Mounting Structure?
It is a lightweight yet strong mounting solution made of anodized aluminium, used to hold and align solar panels securely on rooftops (RCC, metal sheet, or tin shed) or ground.
Long rails are extruded aluminium profiles that run parallel to the panels, supporting them through clamps and connecting accessories.
🔹 Key Features
Material: High-strength Aluminium Alloy (commonly AL6005-T5).
Surface Treatment: Anodized (≥ 10 micron), ensures corrosion resistance.
Design: Aerodynamic, lightweight, and easy to install.
Compatibility: Suitable for framed and frameless solar PV modules.
Durability: 25+ years lifespan, resistant to rust and environmental wear.
Flexibility: Adjustable tilt angles depending on project design.
Applications: Residential, commercial, and industrial rooftop solar systems.
🔹 Components of Long Rail Structure
Long Rail Profiles – Main aluminium rails (lengths vary: 2100mm / 4200mm / 4400mm).
Mid Clamps – Fix panels between two rails.
End Clamps – Secure panels at the edges.
Rail Splice Kits – For extending rails beyond standard length.
L-Foot / Roof Hook – To mount rails on RCC or sheet roofs.
Fasteners & Bolts – Stainless steel (SS304/316) nuts, bolts, and washers.
🔹 Technical Specifications (Typical)
Material: Aluminium 6005-T5 (extruded).
Surface: Anodized (10–15 microns).
Rail Size: 40x40mm / 40x45mm / 40x50mm (varies by manufacturer).
Length: 2100mm / 4200mm / 4400mm (custom sizes available).
Weight Capacity: Designed for wind speed up to 180 km/h (depending on structure design).
Load Capacity: Complies with IS 875 standards (wind & snow load).
🔹 Advantages
Lightweight but strong → easy transportation & handling.
Rust-proof → better than MS (mild steel) structures in long-term projects.
Easy installation → modular & pre-drilled holes.
Reduces installation time → fewer parts, simple design.
Long service life → matches solar panel lifetime (25+ years).
