· Standard modules can be mounted onto a support structure using one of several approved methods.
One such method is described below.
Use appropriate corrosion-proof fastening materials.
All mounting hardware (bolts, spring washers, flat
washers, nuts) should be stainless steel.
· Use a torque wrench for installation.
· Do not drill additional holes or modify the module frame. Doing so will void the warranty.
· Standard modules can be installed in either landscape or portrait orientations. Refer to the detailed
instructions for further guidance. Please note that in areas with heavy snowfall (> 2400 Pa) further
countermeasures such as the use of additional support bars should be considered to avoid snow loads
damaging the lowest row of modules.

MOUNTING METHOD: BOLTING
· Modules should be bolted to support structures through the mounting holes in the rear frame flanges only.
· Each module must be securely fastened at a minimum of 4 points on two opposite sides, using the innermost
mounting holes. M6 size bolt and nut shall be used for bolting method. Tightening torques should be within 4 ~ 6 Nm
(3.0-4.4 ft-lbs) for M6x1 coarse thread bolts, depending on bolt class. In areas with heavy wind loads, additional
mounting points should be used. The system designer and the installer are responsible for calculating the loads and
ensuring that the support structure meets the requirements.
Mounting method: Bolting
· Modules should be bolted at the following hole locations depending on the configuration and load:
