3.4 Additional Mounting Methods
Use of the PanelClaw system (Polar Bear
®
III) is
recommended with Silvantis modules. Structures
manufactured by PanelClaw Inc. use a special clamp, or
"claw" designed to attach to the flange of the module at all
four corners, on the two short frame ends.
For proper placement, attach a claw over the module
frame flange at each of the four designated locations and
tighten the screw so that the claws are flush with the
long and short ends of the module flange. This mounting
method has been tested to a maximum rating of 50 psf in
the negative and positive direction. Refer to case two in
Figure 1(a), as well as the PanelClaw installation guide for
information on the installation of the clamps.
Use of the SunEdison AP90 Single Axis Tracker is
authorized for use as well. Please refer to the AP90
installation guide for specific instructions. Installation
guides can be found on the SunEdison website.
