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
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 Rails Material : Aluminum, Stainless steel, etc.
→ We recommend more than 40x40mm mounting rails.
Mounting
• 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 40mm, 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.
