4.2.1
Mounting with bolts

4 or 8 pre-drilled mounting holes, located on the aluminum alloy frame, are
provided for ease of installation. They are designed to be used with metric M8
stainless steel screws. We recommend to use a tighten torque of 16~20 N.m

The module must be attached and supported by at least four bolts through the
indicated mounting holes.

Most installations will use the four inner mounting holes on the module frame.

Depending on the local wind and snow loads, additional mounting points may
be required.

The frame of each module has 8 mounting holes used to secure the modules
to support structure, the moudle frame must be attached to
a mounting rail using M8 corrosion-proof bolts togethter 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. Please find detailed
mounting information in the below, figure A,1,2,5.
4.2.2
Mounting with clamping hardware

When choosing clamp mounting method, please be sure to use at least four
clamps on each module, two clamps should be attached on each long sides
of the module. Depending on the local wind and snow loads, if excessive
pressure load is expected, additional clamps or support would be required to
ensure the module can bear the load. The applied torque value should be
big enough to fix the modules steadily (we recommend the torque range of
screw tightening is between 16 to
18N.m for M8 bolt, 9N.m for M6
bolt. please consult with the clamp
or support’s supplier for the specific
torque value). Please find details
