IronRidge clamps provide a universal method for securing most popular solar PV modules in solar racking systems.  Both the XRS and XRL solar PV rails have slots for top mounting. End clamps and mid clamps are manufactured from either 5052-H32 aluminum or extruded aluminum, depending on the clamp size.

End clamps are used when top-mounting modules to the top slot of both our Standard (XRS) and Light (XRL) Rails (these end clamps fit both rail types). These clamps are not dependent upon the module’s mounting holes. IronRidge End Clamps require 1.5” of rail on each end and vary in height depending on the module being mounted.

Calculating Rail Length

Calculate total required mounting widths as follows:
Add module widths + .25” space between modules for mid clamps + 1.5” to each end for end clamping. This formula will provide you with total width of rails. If rail splices are needed, see IronRidge Internal Rail Splice.

For example, to mount five modules that are each 40” wide, the calculations are as follows:

  • 5 x 40” = 200” (account for width of modules in portrait mode)
  • 4 x .25” = 1” (account for width of mid clamps between the five modules)
  • 2 x 1.5” = 3” (account for two end clamps on ends of rail)
  • 200” + 1” + 3” = 204” (total length of one rail)
  • Two 18’ rails will be required to mount these five modules

* IronRidge rails lengths are: 11’, 14’, 17’.

Calculating Panel Clamp Size

Module Clamp size depends on the module thickness. Use the table below to determine which Module Clamp will fit your projects module thickness.
