When installing modules in heavy snow areas,
it is recommended to be taken an appropriate
countermeasure to prevent possible damages to the
lower side frame by slipping snow.
We recommend to use corrosion resistant material
according to standard UL 1703 or UL2703 for these
supporting part. (A snow guard should be installed in
accordance with the manufacturer’s instructions.)

Mounting by using frame bolts holes
•
Secure the solar module to the structure by using the
factory mounting holes.
•
Four M8(5/16inch) stainless steel bolts, four nuts,
four spring washers, and eight flat washers are
recommended per solar module.
•
The module may be fastened to a support by using
both the outer and inner bolt holes of the frame.
•
Each module should be securely fastened at a
minimum 4 points on two opposite sides.
•
Specific information on the solar module dimensions
and location of mounting holes is provided in ‘Product
Specifications’.
•
Tighten the bolt securely by using the combination
shown above. Place the spring washer between the
Flat washer and Nut.

Mounting by using clamps
•
The module may be fastened to a support by using
clamps on both the long edge and the short edge of
the modules.
•
Specific information on location of clamping is
provided in ‘Mechanical Installation Scene’. (Refer to
Appendix.)
→ If you use a special clamp, it needs to test for
compatibility by LGE.
•
If the installation is likely to be affected by
heavy(extreme) snow, further suitable panel support is
recommended on the lower row of panels.
