Modules must be securely attached to the mounting structure using pre-drilled mounting holes in the frame.
Modules should be bolted to support structures through mounting holes located in the frame's back flanges
only. Do not drill additional holes. Doing so will void the warranty.
Use appropriate corrosion-proof fastening materials. All mounting hardware (bolt/split washer/flat
washer/nut) should be stainless steel M8 size.
Follow mounting guidelines recommended by the PV mounting supplier. The mounting design must be
certified by a registered professional engineer.
The mounting design and procedures shall comply with local codes and all authorities having jurisdiction.
Use a torque wrench for installation. Tightening torques should be within 10~17 Nm for M8 coarse thread
bolts, depending on bolt quality class.
Ensure that the drainage openings of the frame are left open following installation to allow water runoff.
This prevents frost damage.
Install the module in such a way that rainwater and snow melt can run off freely to avoid standing water or
pudding.
This resistance value can decrease if modules are not mounted following the instructions above.
(B) Clamping installation (Only for frame with 40mm thickness)
Modules can be installed with clamps. Modules must be securely attached to the mounting structure with four
clamps on the long frame.
The modules must be properly secured to their support so that they can withstand live load condition,
including wind uplift, to the pressure they have been certified for. It’s the installer’s responsibility to ensure
the clamps used to secure the modules are strong enough.
The modules are not subject to wind or snow loads exceeding the maximum permissible loads.
The module clamps which are used must not come into contact with the front glass and must not deform the
frame. Avoid shadowing effects from the module clamps. Drain holes in the module frame must not be closed
or obscured by the clamps.
