INSTRUCTION OF INSTALLATION METHODS
SCREWS
Modules can be attached through the mounting holes on the back
INSTALLING
frame of the module, by fixing the module to the support rails with
METHOD
bolts. The mounting details are shown in the following figures.
Mounting Hole

Secure the module in each mounting location with an M8 bolt and a flat washer, spring washer and nut as shown in
Figure 1 and tighten to a torque of 16~20 N.m(140-180lbf.in.).
All parts in contact with the frame should use flat stainless steel washers of minimum 1.8mm thickness with an outer
diameter of 20-24mm (0.79-0.94in).
All mentioned clamp mounting methods here are only for reference, DAH Solar will not
be responsible for the system design and installation. The mechanical loads and its
safety must be operated and completed by the professional solar system installer and
NOTES
experienced installation team.
The frame of each module has 4-φ9*14mm
mounting holes, ideally placed to optimize
the load handling capability, to secure the
modules to supporting structure.

When choosing this type of clamp-mounting method, use at least four clamps on each module, two clamps should be
attached on each long sides of the module (for portrait orientation) or each short sides of the module (for landscape
orientation). Depending on local wind and snow loads, additional clamps may be required to ensure that modules can
bear the load.
