End Clamps
Verified by SOLBE Structural Engineering Board
Definition
End clamps are precision-engineered structural fasteners used to secure the outermost solar modules of an array to the supporting solar rails, locking the modules in place and preventing lateral or vertical sliding.
Technical & Structural Breakdown
An end clamp holds the frame of the terminal solar module using a specific clamping height matching the module’s frame thickness (typically 30mm, 35mm, or 40mm). They are tightened using high-tensile stainless steel fasteners (typically A2-70 or SS304) into the rail’s channel guides, creating a friction-grip lock capable of withstanding severe wind uplift forces calculated under IS 875 Part 3 standards.
