Mounting Installation - SCHOTT Solar Photovoltaic Modules Installation And User Manual

1.6 Mounting and Installation
There are several approved ways to mount the SCHOTT POLY™ modules to a support
structure. They may be mounted in either portrait or landscape orientation using either
the bolt holes provided or using frame clamps (not provided). For all mounting methods
a minimum gap of 1/4" (7 mm) between modules is required to allow for thermal
expansion. For roof mounted systems a minimum gap of 1" between the module and
the roof surface is required to allow for greater ventilation.
The modules may be fastened to a support using the bolt holes in the bottom of the frame
shown in Figure 1. The module should be fastened at four points, with a 5/16" (M8) bolt,
washers and a nut (not provided).
Inter-module type or end-type clamps must be designed for PV modules and have
minimum dimensions shown in Figure 2 and installed in accordance with the instructions
below and drawings provided. The mounting clamps should be at least 1.5" (38 mm)
long, at least 0.12" (3 mm) thick, and have a catch width of at least 0.2" (5 mm). When
installing, the clamp must overlap the support rail by at least 0.4" (10 mm) and be placed
within the permissible clamping zones shown in Figure 3. For the high load situations
shown in Figure 3 an additional center support rail should be used. Note that SCHOTT
does not warranty frame clamps. The SCHOTT module warranty may be void if
customer-selected frame clamps are improper or inadequate with respect to properties
(including strength or material) or installation.
