How to use a frame installation hole
1) How to use a frame installation hole
Please install the module at the angle having the most annual cumulative amount of solar radiation in the applicable site.
2) Confirmation matter
a)
To improve module's electrical insulation and durability, the back side [Junction Box] of module should be
protected to avoid exposure to moisture, and PV module wiring should be installed considering thermal
expansion due to ambient temperature and vibration due to wind.
b)
When a PV module is installed on a roof, between the back side of the PV module and roof is maintained at
a sufficient distance(minimum above 2 inch) to be well ventilated.
c)
According to the laws of the applicable site, the PV module can be installed on a fire resistance roof.
d)
For UL 1703, the PV module's system class ' A ' fire rating. And for IEC 61730, the fire rating is 'C'.
e)
Only for UL 1703, the modules with the specified construction in below table, when used with a Listed mounting
system that has been rated as a Class 'A' System when installed with type 1 or type 2 modules, is suitable to
maintain the System Class ' A ' Fire Rating.
f)
Only for UL 1703, The fire rating of the module is valid only when mounted in the manner specified in the
mechanical mounting instructions.
3) Installation hole
The method of installing a frame hole passed a mechanical load test item in accordance with the IEC 61215 and
UL 1703 standard, and S-Energy Co., Ltd. recommends the following method of installing a frame hole.
As described in <fig. 1>, an installation hole is inserted in the frame, if the frame is randomly processed or the
installation hole is changed, the module will be damaged or the strength of frame will be declined.
Hole Installation
CAUTION
1)
Be careful to avoid sealing the gap between the module and the structure, because the area should be well
ventilated. The module of power performance and life can be affected, if the space between the module and
structure is sealed.
2)
Please leave a space between the modules because the module can be expanded or be shrink depending on the
ambient temperature.
3)
In case of failure to use the accessories recommended by S-Energy Co., Ltd., it may affect the long term reliability
of the module, and S-Energy Co., Ltd. do not take any responsibility for life-shortening of the module resulting
from such use.
Modules can be attached through the mounting holes on the
-
back frame of the module , byfixing the module to the support
rails with bolts.
The frame of each module has 8 mounting holes, ideally placed to
-
optimize the load handling capability , to secure the modules to
supporting structure.
To maximize mounting longevity , S-energy strongly recommends
-
the use of corrosion proof (stainless steel) attachment hardware.
The tightening torque (suggest stainless steel M8 bolts) should be
-
around 15-20 Nm.
