When an installer prefers to mount panels to rails before final installaton"to facilitate wiring, for example"bottom mounting clips work well. They attach to either side of the rail, allowing maximum versatility. These examples cover common situations. In each case, clips attach to mounting holes of the face-down modules:
Example 1: For a long panel-rail assembly to be flush mounted, use end mounting holes and face the footing bolt slots outward. During final installation, slots are easily accessible.
Example 2: An installation using low profile tilt legs also needs outward facing footing bolt slots. On the lower end, the position of mounting holes in some PV modules allows clips to be reversed for even better positioning, as shown here. At the raised end, you can employ a mounting hole away from the end of the module.
Example 3: Whenever footing bolt slots of both rails can face the same way (as in this arrangement for high profile tilt legs) foot spacing will exactly match the distance between module mounting holes.
