Solar Rails
Verified by SOLBE Structural Engineering Board
Definition
Solar rails are extruded structural profiles, typically fabricated from high-strength Aluminium Alloy 6063-T6 or Hot-Dip Galvanized Iron, that serve as the primary mounting beams supporting solar photovoltaic modules on rooftops or ground mounting systems.
Technical & Structural Breakdown
Designed as load-bearing framing members, solar rails distribute panel weight and wind loads to the underlying rafters or brackets. They feature built-in slots (typically T-slots or channel guides) for end clamps, mid clamps, and structural fasteners, enabling rapid assembly and modular panel alignment. In engineering calculations, rail sizing must satisfy deflection limits (typically L/180 or L/240) as per IS 875 Part 3 wind speed parameters.
