• 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) 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.
• Applied torque should refer to mechanical design standard according to the bolt customer is using, ex:
• M6 ---- 9 N.m (70lbf.in)
• M8 ---- 16-20N.m(140-180lbf.in)
