Mechanical Installation
Mounting Methods
General Information
• Select the appropriate orientation to maximize
sunlight exposure.
• In order to prevent water from entering the
junction box, which could present a safety hazard,
module should not be mounted such that the
front/top glass faces downward.
• Clearance between the solar module frames and
structures such as roofs or ground is required to
prevent wiring damage and to allow air to
circulate
behind
the
recommended standoff height is a minimum of
100mm.
• When installed on a roof, the solar module must
be mounted over a fire-resistant roof covering
rated for the application. The fire resistance of the
solar module from LG Electronics is class C after
ANSI/UL790.
• The solar module is only IEC listed for use when
its factory frame is fully intact.
• Do not remove or alter the solar module frame.
• Creating additional mounting holes may damage
the solar module and reduce the strength of the
frame.
• A 6mm gap between module frames should be
allowed to avoid tension from thermal expansion.
• The solar module may be mounted using the
following methods: (*Torque:8~12Nm )
• When installing modules in heavy snow areas,
special care should be taken to install the
modules in a manner that provides sufficient
design strength while meeting local code
requirements.
Mounting by using frame bolts holes
• Secure the solar module to the structure using
the factory mounting holes.
• Four M8 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 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
dimensions and location of mounting holes is
provided in 'Product Specifications'.
• Tighten the bolt securely using this combination.

Mounting by using clip or clamps
• The module may be fastened to a support using
clips or 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 Appendix.).
• The module frame must overlap more than 15mm.
Clamp system requirements
• Clamp width is more than 30mm, depth is more
than 10mm. Clamp height compliant with a frame
height.
• The clamp should not be touched with the
module's glass.
• Use corrosion resistant material clamps and
hardware.(If you use a special clamp, it needs to
test for compatibility by LGE.)
• Use appropriate bolted connections as per clamp
manufacturer's instructions.
• Follow the clamp manufacturer's recommended
applied torque to fasten the clamps.
