1.3 Zep Compatible
Zep Solar mounting solutions are based on the Zep Groove, a patented module frame profile
designed to mate easily and precisely with Zep components. Module frames with the Zep Groove
are considered "Zep Compatible", and are offered by PV module manufacturers who have estab-
lished a licensing agreement with Zep Solar, Inc.
Figure 1.2 Zep Groove and Rockit
Key and Tongue.
The Key and Tongue concept informs all Zep Compatible designs. The Key side
inserts into the Zep Groove, similar to inserting a key into a lock. On the other side, the Zep Groove
allows PV modules to “drop in” easily onto the Tongue of the Rockit.
