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 120 V DC and higher. General access is
not restricted.
• 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 field inspection certifying that the installed module
complies with the requirements of UL 1703.
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
• LGE solar modules are certified to basic loads
50lb/ft2 (about 2400 Pa).
Excluded Operating Environments
• The solar modules from LG Electronics can not be
operated in a location where they could come in direct
or indirect contact with salt water or ammonia.
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 fire-resistant roof covering rated for the
application. The fire resistance of the solar module is
class C after ANSI/UL790.
• 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.
•
The fire rating of this module is valid only when
mounted in the manner specified in the mechanical
mounting instructions.
• The module is considered to be in compliance with
UL1703 only when the module in mounted in the
manner specified by the mounting instructions below.
• The solar module may be mounted by using the
following methods: (*Torque:8~12Nm )
Mounting by using frame bolts holes
• Secure the solar module to the structure by using the
factory mounting holes.
• Four M6 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 the solar module dimensions
and location of clamping is provided in
„Product
Specifications‟.
