MECHANICAL INSTALLATION
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.
• The solar modules are in Application Class A and
have the Safety Class II. Therefore they can be
operated in systems with 120V DC and higher.
General access is not restricted.
• 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.
Module Operating Temperature
• T
emperature range : -40°C ~ 85°C (-40°F ~ 185°F)
• The operating ambient temperature of these devices
may exceed 40℃ at full load for all wire sizes if is
determined suitable in the field use application.
Excluded Operating Environments
The solar modules from LG Electronics can not be
•
operated in a location where they could come in direct
contact with salt water or ammonia.
•
Do not use module to replace (or partly replace) roofs
and walls of living places.

Shadow
• LGE solar module should be installed in a proper site
that there is no shadowing affected by building,
chimney, tree, and neighboring module, etc.
Mounting
Rails
• Use corrosion resistant material mounting rails and
hardware.
• Use appropriate bolted connections as per
manufacturer's instructions.
• No electrical parts like cables are located after
installation between laminate and mounting structure.
• LGE solar module is qualified up to a altitude of 4000m.
Mounting Methods
General Information
• Select the appropriate orientation to maximize sunlight
exposure.
The module generates maximum output power when it
faces the sun directly. The tilt angle of the modules
should be selected to optimize seasonal and sunlight
-based performance in the installation place.
• 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 fire-resistant roof covering rated for
the application. The fire resistance of the solar module
is class C after ANSI/UL790 Edition 2004.
The solar module is only IEC listed for use when its
•
factory frame is fully intact.
Removal or alteration must be done by an authorized
•
and qualified 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.
