Module Selection
For detailed key electrical data, please refer to the product data
sheet for the respective product.
ÄFor maximum energy yields, mismatches of specied electric
current (I
MPP
) of more than 5 % should be avoided for all modules
connected in series.
Safety Factor
During normal operation, a module may generate a greater current
and / or higher voltage than that determined under standardized test
conditions. Accordingly, the values of ISC and VOC marked on the
module should be multiplied by a facot of 1.25 when determining:
• the component voltage ratings,
• conductor ampacities,
• fuse sizes,
• size of controls connected to the PV output.
Refer to Section 690-8 of the National Electrical Code for an
additional multiplying factor of 125 percent (80 percent derating)
which might be applicable.
ÄPlease 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).
Series Connection
Connection of modules in series is only permitted up to the
maximum system voltage as listed in the applicable data sheet.
Ä
Take 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.
Ä
Take the voltage limit of the inverter into account when determining
the maximum number of modules in the string.
Parallel Connection
Modules may be damaged by the occurrence of reverse currents
(caused by module defects, ground leaks, or defective insulation).
Ä
Ensure 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 a single
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 specications provided by the respective string fuse manu-
facturer and the technical guidelines.
NOTE!
When installing different product versions, the lowest minimum
permitted reverse current load capacity applies.
Inverters
Inverters with or without transformers may be used.

5 GROUNDING
Functional grounding
• For installations located in tropic regions (between 23.5° N and
23.5° S) with a module tilt of < 5°, functional grounding at the
negative generator connection on the DC side must be implemented.
ÄEnsure that the difference of potential between the negative
generator connection and the PE(N) of every MPP tracker of the
respective inverters is 0 V.
ÄFollow the directions of the inverter manufacturer.
ÄOnly use inverters which include lincensed grounding kits.
ÄFunctional grounding has also to be implemented in installation
sites with increased salt content in the air (e.g. close to the sea).
Protective Grounding
In order to prevent electrical shock or re, 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 specic requirements
on grounding. The U.S. National Electrical Code addresses these
issues in Article 250. Proper grounding is achieved by bonding all
exposed non-current-carrying 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.
Option A: Use of a grounding lug
When a predrilled mounting hole is present in the module frame,
a listed grounding lug can be bonded to the frame. These holes

are marked with a ground symbol, as shown below on the frame
section drawing: To install the grounding lug, follow the specied
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
The Q CELLS modules can be bonded with the racking system
using UL1703 or UL2703 certied 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. An example of such integrated
grounding method is the use of a WEEB clip or Schletter plate
between the module and the racking system, when mounting
the module. The WEEB washers are generally compatible with
Q CELLS modules, however each combination module / racking
system requires a specic WEEB washer size. Note that WEEB clips
are intended for single use only; they must not be reused after
removal or loosening. Refer to Wiley’s installation instructions for
the specic use of WEEB washers.
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 specic 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 specic use of WEEB washers.

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.
Maintenance
ÄThe PV system has to be inspected regularly by certied
personnel
Ä
The time intervals and extent of the inspection can depend
on local circumstances (e.g. salt, ammonia content in
the air, high humidity etc.). The customer/operator must
inform himself about time intervals and extend of necessary
inspections.
Ä
Inspections have to be performed especially after extraor-
dinary events (e.g. storm, hail, high snow loads etc.)
ÄDuring the inspections it has to be checked that the
components are secure, undamaged and clean
Cleaning
WARNING!
Risk of injury due to hot and
live modules!
ÄOnly clean modules that have cooled down.
ÄDo not carry or wear any electrically conductive parts.
WARNING!
Risk of falling due to unsecured
access!
ÄNever access the installation area alone or without
taking adequate security precautions.
ÄPlease commission a trade specialist.
NOTE!
Module surface damage may occur!
ÄRemove snow and ice without force (e.g. with a very
soft broom)
ÄDo not scratch off dirt.
ÄRinse dirt off with lukewarm water (dust, leaves, etc.)
ÄUse a soft cellulose cloth (kitchen roll) or sponge to
carefully wipe off stubborn dirt. Do not use micro eece
wool or cotton cloths.
Ä
Use an alcohol based glass cleaner. Do not use abrasive
detergents or surfactants.
Isopropyl alcohol (IPA) can be used selectively to remove
stubborn dirt and stains within one hour after emergence.
ÄPlease follow the safety guidelines provided by the IPA
manufacturer.
ÄDo not let IPA run down between the module and the
frame or into the module edges.
ÄFree the substructure from any dirt and debris
(leaves, bird nests, etc.).
ÄRemove dirt with lukewarm water, a broom, or a
soft cloth.
ÄDo not use surfactants, scrapers, or any high-
pressure water cleaning equipment.
NOTE! Module damage may occur!
ÄDo not clean modules with water if there is a risk
of frost.
