KD series modules may be attached to a support structure by the following methods. Detailed mounting method is
described in 'mounting table'. When installing modules in snowy area, an appropriate countermeasure has to be taken to
prevent possible damages to the lower side frame by slipping snow (e.g. attach supporting parts to the lowest modules.).
Any damage caused by snow or such countermeasure is not covered under warranty.
For optimal performance in all applications, clearance between the module frame and the mounting surface is required to
allow cooler ambient air to circulate around the back of the module and to avoid the module and / or wiring damage.
The minimum spacing of 2" (50 mm) is required between PV module and the mounting surface around the perimeter of PV
module. There should also be a clearance of at least .13" (3.2 mm) between the individual modules to allow heat-related
expansion.
BOLTING: Utilizing 5/16" or 8 mm steel hardware structure through the existing .35" (9 mm) diameter mounting holes in the
module frame and then through KD series modules mounting holes on the support structure.
Tighten the screws with adequate torque (usually 132 in-lb).
Support structure should have enough strength to keep the mounting span.
Refer to the below table for the position of PV module mounting holes.
CLAMPING: Fasten modules firmly with the clamps which must not be deformed by wind load or snow load, nor cause the
module fall off by using torque values specified by structure manufacturers.
Minimum 40mm clamping width, and minimum 9mm overlap onto frame are necessary.
Clamps also must not shade the sunlight incidence on glass surface.
Clamp material must be either stainless steel or anodized aluminum.
Support structure should have enough strength to keep the mounting span.
Refer to the below table for the permissible clamping range.
