2.3.2
The Installation of Dual Glass Modules with Frame.
The frame of each module has 8 mounting holes (Length* Width: 14mm*9mm) used to secure
the modules to support structure. The module frame must be attached to a mounting rail using
M8 corrosion-proof bolts together with spring washers and flat washers in eight symmetrical
locations on the PV module. The applied torque value should be big enough to fix the modules
steadily. The reference value for M8 bolt is 16~20N*m. As to special support system or special
installation requirement, please reconfirm with the
support’s supplier for the torque value. Please
find detailed mounting information in the below illustration as Figure 2 and Table 5.
