Module Mounting

• The LG Electronics' (LGE) Limited Warranty for solar
modules is contingent upon modules being mounted
in accordance with the requirements described in this
section.
• Any module without a frame (laminate) shall not be
considered to comply with the requirements of UL
1703 unless the module with hardware that has been
tested and evaluated with the module under this
standard or by a fi eld inspection certifying that the
installed module complies with the requirements of UL
1703.
• We recommend to use mounting device(bolt, nut,
washer) made by corrosion resistant material like
stainless steel.

Site Consideration

LGE solar modules should be mounted in a location that
meets the following requirements.
Operating Temperature
• Maximum Operating Temperature: +90°C (194°F)
• Minimum Operating Temperature: -40°C (-40°F)
Design Strength(basic Load)
• 60Cell Modules : 75lb/ft
• 72Cell Modules : 60lb/ft
• Detail of mounting distance is below.

Mounting Methods

general Information
• Select the appropriate orientation to maximize sunlight
exposure.
• Module should not be mounted or stored in a way that
the front/top glass faces downward in order to prevent
water from entering the junction box, which could
cause a safety hazard.
• 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 solar module. The recommended standoff
height is a minimum of 100mm.
• When installed on a roof, the solar module must be
mounted over a fi re-resistant roof covering rated for
the application. The fi re resistance of the solar module
is class C after ANSI/UL790 Edition 2004.
• A slope less than 5in/ft is required to maintain a fi re
class rating.
• The solar module is only ETL listed for use when its
factory frame is fully intact.
• Removal or alteration must be done by an authorized
and qualifi ed individual.
• Creating additional mounting holes may damage the
solar module and reduce the strength of the frame.
• We recommend a 6mm gap between module frames
to avoid tension from thermal expansion.
• The fi re rating of this module is valid only when
mounted in the manner specifi ed in the mechanical
mounting instructions.
• The module is considered to be in compliance with
UL1703 only when the module in mounted in the
manner specifi ed by the mounting instructions below.
• The solar module may be mounted by using the
following methods: (*Torque:8~12Nm )
• LG modules (Fire performance : Type 2) shall be
mounted with racking and mounting products certifi ed
and listed for system fi re class rating in accordance
with UL1703 edition 2014 and UL2703 edition 2014.
• It is recommended to check with local authorities
for fi re safety guidelines and requirements for any
building or structure on to which the panels will be
installed.
