OPTIONS
REQUIREMENTS
All ÄThe loads in the table are related to the mechanical stability of the solar modules. The mechanical stability of the
mounting system including clamps has to be evaluated by the system supplier. The listed test load values have
been determined with the following clamp parameters: clamp width = 1.57 in (40 mm) and clamp depth = 0.39in
(10mm).
ÄThe system installer is responsible for the determination of location-specific load requirements.
ÄEnsure that the connection cables of the junction box do not run between laminate and mounting rails.
ÄModules bend under load. Therefore, sharp objects (e.g. screws, ballast stones, rail ends, rails with burrs or sharp
corners) must not be placed near the module backside so as not to touch the laminate under load.
ÄEnsure that the junction boxes do not touch the mounting structure (e.g. shorts rails, ballast, etc.) or the rooftop under
load. Clamps or insertion profiles etc. must not touch the glass (even under load).
ÄUnbalanced loads (e.g. snow overhangs, snowdrifts) which result in locally significantly increased loads must be
removed or avoided by technical measures.
ÄA minimum support depth of 0.59in (15 mm) is required on the back side of the module.
CL1a, CL3,
FB1, FB2 ÄEnsure that module frame is fixed directly on the rail of the substructure (no spacer allowed between the module and
substructure).
FB2, TB1a,
TB2a, TB1b,
TB2b, mFB2
ÄUse M8 corrosion-proof screws and washers (diameter ≥ 0.62in (15.8 mm)) for mounting slots (Detail A, Fig.1) and
M6 corrosion-proof screws and washers or bobtails for tracker slots (diameter ≥ 0.51 in (13 mm) ; Detail B, Fig. 1).
Mounting screws and washers should have the same material properties.
TB2a, TB2b ÄMounting rails need to extend beyond the middle of mounting holes by at least 0.67 in (17 mm).
mFB2 ÄMounting rails need to extend beyond the middle of clamps or middle of mounting holes by at least 0.79 in (20 mm).
Clamps must not extend beyond the mounting rails.

Module Selection
For detailed key electrical data, please refer to the product data
sheet for the respective product. (available at www.q-cells.us).
ÄFor maximum energy yields, mismatches of specified electric
current (IMPP) 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.
ÄTake 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.
ÄTake the voltage limit of the inverter into account when deter-
mining 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).
ÄEnsure 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:
Use overcurrent devices (e.g. fuses) according to the relevant
standards in each string. Use gPV-fuses according to IEC 60269-6.
Observe the maximum permitted number of strings as indicated
in the specifications 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
Protective Grounding
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. A module with exposed conductive parts is
considered to be in compliance with this standard only when it is
either electrically grounded in accordance with the manufacturer’s
instructions and the requirements of the National Electrical Code,
ANSI/NFPA 70 (2014-2017), or when the bonding means has been
evaluated with this module to UL 2703.
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 appro-
priate for any individual installation will depend on multiple factors.
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 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
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. 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 specific
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 specific 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 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.

8 MAINTENANCE AND CLEANING
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 certified
personnel.
ÄThe 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.
ÄInspections have to be performed especially after extraordinary
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 ade-
quate security precautions.
ÄPlease commission a trade specialist.
NOTE!
Module surface damage may occur!
ÄRemove snow and ice carefully without force (e.g. with a very
soft broom).
ÄDo not scratch off dirt.
ÄModule cleaning has to be done by qualified personnel accord-
ing to the state of the art and taking into account all relevant
safety issues and general product properties, e.g., but not
restricted to:
• electrical safety
• mechanical stability (load limits depending on the actual
mounting options)
• chemical suitability (no effect to any of the module's compo-
nents, e.g. cable, connector, silicone)
• no abrasive materials.
NOTE!
Dust and dirt are abrasive materials!
ÄThe situation for each individual project (or type of dirt) must
always be professionally evaluated.
ÄWrong cleaning may cause damages such as, but not limited
to, damages to the glass surface (e.g. scratches) and AR coat-
ing, power loss, delamination, loss of frame-to-laminate bond,
reduced snow and wind load capability etc.
Apart from the above, each customer is free to choose the method
of cleaning. However, possible damages, caused by the cleaning
or related to the cleaning tools or agents shall not be covered by
the module's Product and Performance Warranty. Therefore it is
recommended to use only the tools and agents which have already
been successfully tested and used with PV modules, to prevent
possible damage.
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 man-
ufacturer.
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.).
NOTE! Module damage may occur!
ÄDo not clean modules with water if there is a risk of
frost.
