Step 1: Build the Solar Module Assembly
There are 5 substeps involved in building the solar module assembly. Step 1 is completed at the ground
level:
Figure 15 shows all of the attachments of the solar framed module:
Step 1a: Install the Solar Mounting Feet...
There are 5 solar mounting feet that must be attached to
the underside of the solar module along the longer edge. This particular edge is identified by
a channel on the underside of the edge with the exposed wiper seal. Identify the MLPE foot.
The MLPE foot is shaped differently from the other solar feet and has a UL label attached on
the underside The MLPE foot is used to attach the power electronics.
To install the solar mounting feet, first hook each solar foot onto the channel along the solar
module frame. Position the five solar mounting feet so that the pre-drilled holes in the feet
and the module frame align. As shown in Figure 2, note the location of the MLPE foot relative
to the solar module. The MLPE solar foot should be located one from the middle on the side
closer to the solar junction box. This ensures that the cables being routed from the solar
module’s junction box to the MLPE is sufficient in length. Next, rotate it into position and drill
a hex grounding screw into the pre-drilled hole to lock it in place (Figure 17). Torque the screw
to 40 psf (195 kg/m
2
). This achieves an electrical bond and mechanically secures the foot to
the frame. Continue this step until all the solar mounting feet are installed (Figure 18, next
page).
