Parallel Connection
For detailed key electrical data, please refer to the product data
sheet for the respective product.
ÄÄOnly connect modules of the same type and the same power
class.
Modules may be damaged by the occurrence of reverse currents
(caused by module defects, ground leaks, or defective insulation).
ÄÄEnsure that the maximum reverse current load capacity indicated
in the data sheet is met.
In order to limit reverse currents that may occur, we recommend
using the following safety options:
1) Layout with a limited number of parallel connected strings :
Without undertaking further current blocking measures, a maximum
of two module strings may be operated in parallel on an inverter or
MPP tracker.
2) Layout with string fuses :
Place fuses for each string of modules at the plus and minus ends.
Observe the maximum permitted number of strings as indicated
in the specifications provided by the respective string fuse manufacturer and the technical guidelines.
Safety Factor
During normal operation, a module may generate a greater current
and / or higher voltage than that determined under standardized test
conditions. Please use a safety factor of 1.25 for the following:
• Calculating the voltage measurement values (Voc) of components
• Calculating the current measurement values (ISC) of conductors
• Sizing of control systems connected to the outlets of the solar
modules
ÄÄPlease follow the valid national guidelines for the installation
of electrical systems (refer to section 690-8 of the NEC for an
additional multiplying factor of 125 percent [80 percent derating]
which may be applicable).
ÄÄMaintain an interval of at least 0.20 in (5 mm) between two modules along the long side
Series Connection
MOUNTING OPTIONS CL1
Connection of modules in series is only permitted up to the
maximum system voltage as listed in the applicable data sheet.
ÄÄTake into account all possible operating situations and all relevant
technical norms and regulations when designing the system.
This will ensure that the maximum system voltage, including all
necessary safety margins, is not exceeded.
ÄÄTake the voltage limit of the inverter into account when determining
the maximum number of modules in the string.
ÄÄEnsure, that the subconstruction does not run below the junction box.
ÄÄEnsure, that the connection cables of the junction box don‘t run between laminate and substructure.
MOUNTING OPTION FB1
ÄÄUse M8 corrosion-proof screws and washers (min. diameter 0.63 in (16 mm)).
ÄÄEnsure, that the connection cables of the junction box don‘t run between laminate and substructure.
• The fastening points are located on the backside of the module frame.

ELECTRICAL CONNECTION
4.1 Safety
DANGER!
Risk of fatal injury due to electric shock!
When disconnecting an electric circuit carrying direct current,
electric arcs can occur that may result in life-threatening injuries.
ÄÄDo NOT unplug the cable when under load.
ÄÄDo NOT connect any exposed cable ends.
ÄÄDo NOT touch the poles at the same time.
A solar module generates electrical current and voltage even at a
low intensity of illumination. Sparks and electric arcs may result
from the separation of a closed circuit. These can result in lifethreatening injuries. The danger increases when several modules
are connected in series.
ÄÄPlease be aware of the entire open circuit voltage is active even
at low levels of solar irradiation.
ÄÄPlease follow the valid national regulations and safety guidelines
for the installation of electrical devices and systems.
ÄÄPlease make sure to take all necessary safety precautions. With
module or phase voltages of more than 120 V, the extra-low
voltage range is exceeded.
ÄÄCarry out work on the inverter and the wiring with extreme caution.
ÄÄEnsure that the modules are disconnected at the inverter prior
to separation.
ÄÄBe sure to observe the specified time intervals after switching off
the inverter. High-voltage components need time to discharge.

with a ground symbol, as shown below on the frame section drawing:
To install the grounding lug, follow the specified instructions of
the manufacturer. The grounding lug should be made of stainless
steel or tin plated metals such as aluminum to avoid corrosion. The
grounding lug should be attached to the frame grounding hole using
a stainless steel screw, toothed lock washer or KEPS nut (in order
to penetrate the anodized layer) and backing nut. Care should be
taken to avoid the use of grounding hardware of dissimilar metals,
which may lead to corrosion

Option B: Integrated grounding methods
In order to prevent electrical shock or fire, the frame of the module
as well as any non-current-carrying metal parts of the system must
be grounded. While this section provides some information about
grounding the Q CELLS frames and modules, reference should be
made to local statutes and regulations for specific requirements
on grounding. The U.S. National Electrical Code addresses these
issues in Article 250.
The Q CELLS modules can be bonded with the racking system using
UL1703 or UL2703 certified integrated grounding methods. The
racking system will then have to be grounded so that the overall system
is properly grounded. The listed racking system and grounding device
should be installed in accordance with the manufacturers’ instructions.
Proper grounding is achieved by bonding all exposed non-currentcarrying metal equipment to the appropriately sized equipment
grounding conductor (EGC) or racking system that can be used for
integrated grounding.
Q CELLS frames are protected from corrosion with an anodized
coating, which has to be penetrated in order to ensure proper
bonding. The different methods listed below are suggested
methods for an appropriate bond between the frame and the EGC
or racking system (that will have to be properly grounded). The
method appropriate for any individual installation will depend on
multiple factors.
FAULTS AND DEFECTS
DANGER!
Risk of fatal injury due to electric shock!
ÄÄDo not attempt to fix any problems yourself (e.g., glass
cracks, damaged cables).
ÄÄPlease contact an installer or Q CELLS Technical Customer
Service Department.
7DISPOSAL
ÄÄDo not disconnect modules yourself.
ÄÄPlease commission a trade specialist.
ÄÄDispose of modules in accordance with the local disposal
regulations.
An example of such integrated grounding method is the use of a
washer recognized as meeting UL2703 requirements between the
module and the racking system, when mounting the module. For
example, WEEB washers are generally compatible with Q CELLS
modules, however each combination module / racking system
requires a specific WEEB washer size. Note that WEEB washers
are intended for single use only; they must not be reused after
removal or loosening. Refer to Wiley’s installation instructions for
the specific use of WEEB washers.
Option A: Use of a grounding lug
A listed grounding lug can be bonded to the frame using the
grounding holes pre-drilled in the frame. These holes are marked

MAINTENANCE AND CLEANING
Hanwha Q CELLS solar modules are known for a long
operating life and minimal maintenance effort and
expense. Dirt and grime are usually washed away by rain.
If the module is fully or partially shaded by dirt or debris
(e.g., plants, bird droppings), it needs to be cleaned to
prevent a loss of performance.
NOTE! Module damage may occur!
ÄÄDo not clean modules with water if there is a risk
of frost.
0°
Maintenance
ÄÄThe system should be inspected by an installer annually
to check the following:
• all system components sit securely and are corrosion
free.
• the connection is secure and all electrical components
are clean and undamaged.

Cleaning
WARNING!
Risk of injury due to hot and
live modules!
ÄÄOnly clean modules that have cooled down.
ÄÄDo not carry or wear any electrically conductive
parts.
ÄÄRemove dirt with lukewarm water, a broom, or a
soft cloth.
ÄÄDo not use tensides, scrapers, or any high-pressure
water cleaning equipment.
WARNING!
Risk of falling due to unsecured
access!
ÄÄNever access the installation area alone or without
taking adequate security precautions.
ÄÄPlease commission a trade specialist.
Clean the modules as follows:
NOTE!
Module surface damage may occur!
ÄÄRemove snow and ice without force (e.g. with a very
soft broom)
ÄÄDo not scratch off dirt.
ÄÄRinse dirt off with lukewarm water (dust, leaves, etc.)
ÄÄUse a soft cellulose cloth (kitchen roll) or sponge to
carefully wipe off stubborn dirt. Do not use micro fleece
wool or cotton cloths.
ÄÄUse an alcohol based glass cleaner. Do not use abrasive
detergents or tensides.
ÄÄFree the substructure from any dirt and debris
(leaves, bird nests, etc.).
Isopropyl alcohol (IPA) can be used selectively to remove
stubborn dirt and stains within one hour after emergence.
ÄÄPlease follow the safety guidelines provided by the IPA
manufacturer.
ÄÄDo not let IPA run down between the module and the
frame or into the module edges.
