• After installation or repair, check whether solar
module operates properly or not.
• In case the currently used solar module or the
parts applied to the solar module have been
replaced, check whether the changed solar
module is properly operated or not. The newly
replaced solar module and its parts must be the
same solar module(module name) and parts with
the current solar module.
• Please contact the local office to confirm the
regulations and to obtain permission.
• Do not let anyone approach the solar module
who has little knowledge of solar modules or on
the measures to take when solar modules are
damaged in order to avoid the risk of injury or
electrical shock.
• Do not locate the solar module horizontally, as
this may cause dirt or white efflorescence (glass
deformation)
• Panels produce voltage even when not
connected to an electrical circuit or load.
• Panels are intended for outdoors, land based
applications only. Panels are not intended for use
indoor use or application on moving vehicles of
any kind.
• Reflection from external environments such as
snow, water or other surfaces can increase the
power generated by the panel.
• Industry standard rated specifications are made
at conditions of 1000W/m2irradiance and 25°C
(77ºF) solar cell temperature. Colder temperatur-
es can substantially increase voltage and power.
• Keep the solar module and system away from
children when installing.
• Keep the module packed in the carton until the
time of installation.
• Make sure flammable gases are not generated
near the installation site.
• Do not work alone. Please work as part of a team
of two or more people.
• Wear a safety belt if working high above the
ground.
• Contact with electrically active parts of the panels,
such as terminals, can result in burns, sparks and
lethal shock whether the panel is connected or
disconnected.
• Even partial shadowing can substantially reduce
panel and system output.
• Care must be taken to avoid low tilt angles which
may cause dirt to buildup on the glass against the
frame edge.
• Dirt build-up on the surface of the panel can
cause active solar cells to be shaded and
electrical performance to be impaired.
• Always keep the back surface of the panel free
from any foreign objects or structural elements
which could come into contact with the panel,
especially when the panel is under mechanical
load.
• For permission to use mounting methods not
described in the Mounting Guide please consult
LG Solar. Failure to do so will void the warranty
and panel certification.
After Installation
•Plug the connector in tightly and ensure that the
wiring properly works.
• It is advisable to conduct periodic inspection of
the panels for damage to front glass, back sheet,
frame, junction box, or external electrical
connections.
• Check electrical connections for loose connec-
tions and corrosion.
• PV panels can operate effectively without ever
being washed, although removal of dirt from the
front glass can increase output.
•Water, ethanol or a conventional glass cleanser
with a micro-fiber cloth can be used for regular
washing or rinsing of the front glass to remove
dust, dirt or other deposits.
• No aggressive and abrasive cleansers or
chemicals such as alkali chemicals including
ammonia based solution should ever be used on
the treated front glass.
• Always wear rubber gloves for electrical
insulation while maintaining, washing or cleaning
panels.
• Deposits of foreign material on the frame surface
can be cleaned using a wet sponge or cloth and
dried in air or by using a clean chamois.
• Perform the wiring work by connecting the
connector and wires to the stand away from the
roof or ground.

Electrical Installation
Caution
•Avoid all electrical hazards when installing, wiring,
operating and maintaining a panel.
•Do not use panels of different electrical or
physical configurations in the same system.
•Match the polarities of cables and terminals when
making the connections; failure to do so may
result in damage to the panel.
•When reverse currents can exceed the value
marked on the name plate, a properly rated and
certified over-current device (fuse or circuit
breaker) must be connected in series with each
panel or string of panels.
•The rating of the over-current device shall not
exceed the maximum series fuse rating marked
on the name plate.
•The panel contains factory installed bypass
diodes located inside the junction box.
•When installing the system, it is recommended to
install the lightning rod to protect the system.
•The junction box should not be opened. Opening
the junction box may void the warranty.
•Panels with a suspected electrical problem
should be returned to LG Electronics for
inspection andpossible repair or replacement as
per the warranty conditions provided by LG
Electronics.
Electrical Connections
•Modules may be connected in series and/or
parallel to achieve the desired electrical output as
long as certain requirements are met.
•Please use only the same type of modules in a
combined source circuit.
•Do not disconnect the module under load.
Shock hazard can occur near the solar modules
connection means.
Series Connection
•The solar modules may be wired in series to
produce the desired voltage output.
•The current of each module connected in series
should be same.
•The maximum number of series connected
modules can be determined by basis on max.
system voltage, the 125% safety factor, and the
module Voc which can be checked in “Product
Specifications” in this document.
•Do notexceed 80% of maximum system voltage.
•The maximum solar module configuration can be
found in “Product Specifications”.
Series connection for more voltage
Parallel Connection
•The solar modules may be combined in parallel
to produce the desired currentoutput.
•When modules are combined in parallel, the total
current is equal to the sum of currents from each
module.
•The voltage of each module connected in parallel
should be same.
•When connecting plural strings of modules in
parallel every series string or solar module must
be fused prior to combining with other strings.
By pass diodes are factory installed in the solar
modules.
•Please refer to the applicable regionaland local
codes for additional fusing requirements and
limitations on the maximum number of solar
modules in parallel.
•Maximum series fuse rating is refer to “Product
specifications;page 8”.
•A multiplying factor is required for increased
output of the PV modules. Under normal
conditions, a PV module is likely to experience
conditions that produce more current and/or
voltage than reported at standard test conditions.
Accordingly, the values of Isc and Voc marked on
this PV module should be multiplied by a factor of
125% when determining component voltage
ratings, conductor ampacities, fuse sizes, and
size of controls to the PV output.
•Depending on national directives additional
safety factors might be applicable for overcurrent
protection.
