A.
Mounting
with Bolts
The frame of each module has 4 x
φ
9mm mounting holes, ideally placed to optimize the load handling capability, to
secure the modules to supporting structure.
To maximize mounting longevity, Trina Solar strongly recommends the use of corrosion proof (stainless
steel) fixings
Secure the module in each fixing location with an M8mm bolt and a flat washer, spring washer and nut as
shown in Figure 1 and tighten to a torque of 16 Nm.

Mounting with Clamps
:
Trina Solar has tested its modules with a number of clamps from different manufacturers and recommends
the use of clamps which have an EPDM or similar insulating washer, fixing screw of at least M6. The clamp
must overlap the module frame by at least 7mm but no more than 10 mm.
Use at minimum 4 clamps to fix modules on the mounting rails.
Modules clamps should not come into contact with the front glass and must not deform the frame.
Be sure to avoid shadowing effects from the module clamps.
The module frame is not to be modified under any circumstances.
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) and 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.
Applied torque should be 8 Nm. Please find detailed mounting information in the illustration below:
