2.2 Requirements
Installation Site
Please note the following guidelines that apply to the installation
site:
■Solar modules are not explosion-proof and are not suitable for
use in explosive environments.
Do not operate solar modules near highly flammable gas and
vapors (e.g. gas tanks, gas stations).
Do not install modules in enclosed space.
Do not install modules in locations where they may be
submerged in water (e.g. floodplains).
Do not use modules as a substitute for the normal roofing (e.g.
modules are not watertight).
Do not install modules in close proximity to air conditioning
systems.
Do not install modules above 13,120 ft (4,000 m) altitude above
sea level.
Contact with saline water (e.g. spray water from the sea) and
salt aggregation on the modules must be avoided.
Do not bring any chemical substance (e.g. oil, solvent etc.) into
contact with any part of the panel. Only substances, which are
released by Qcells, are allowed to be used during installation,
operation and maintenance.
Any installation of modules on surfaces of water is prohibited.
This includes installations on floating as well as pile-based
platforms. Qcells may extend the coverage of its warranty to
such installations, based on a case by case assessment of
the system design and location. A prior written consent by the
warrantor is required in any case.
Prevention of Shadowing Effects
Optimal solar irradiation leads to maximum energy output:
For this reason, install the modules so that they face the sun.
Avoid shadowing (due to objects such as buildings, chimneys
or trees).
Avoid partial shading (for example through overhead lines, dirt,
snow).
Limitations
The solar modules are designed for the following applications:
■Operating temperatures from –40 °F to +185 °F.
■Pull loads and push loads according to chapter 2.3 (‘Test
Load’ in accordance with IEC 61215 and ‘Design Load ×1.5’ in
accordance with UL 61730).
■Installation using a mounting structure for solar modules.
Mounting Structure Requirements
Requirements for the mounting structure:
■Conform to the necessary structural requirements.
■Compliant with local snow and wind loads.
■Properly fastened to the ground, the roof, or the façade.
■Forces acting on the module are relayed to the mounting
substructure.
■Ensures sucient rear ventilation of the module.
■Avoid the usage of different metals to prevent contact
corrosion.
■Allows for stress-free expansion and contraction due to
temperature fluctuations.
Ensure that no additional forces are applied through the
mounting system into the module except for the wind and
snow loads. Additional forces and moments of torque at the
mounting positions caused by torsions, displacements or
vibrations in the mounting system are not allowed.
Ensure that the clamps and the mounting frame are compatible.
Clamp System Recommendations

■Clamp width: ≥ 1.57 in (40 mm).
■Clamp height compliant with a 1.18 in (30 mm) frame height.
■Clamp depth: 0.28-0.47 in (7-12 mm). (applicable for all CL
clamping mounting options at section "2.3 Mounting options")
■Clamps are not in contact with the front glass.
■Clamps do not deform the frame.
■Clamps that satisfy the structural requirements based on the
conditions of the installation site according to the applicable
regulations and technical standards.
■Long-term stable clamps that securely ax the module to the
mounting frame.
Module Orientation Requirements
■Vertical or horizontal installation is permitted.
Ensure that rain and melting snow can run o freely. No water
accumulation.
Ensure that the drainage holes in the frame are not covered.
No sealing.

2.3 Mounting options
REQUIREMENTS OF ALL MOUNTING OPTIONS
The 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 = 0.39 in (10 mm).
The system installer is responsible for the determination of location-specific load requirements.
Ensure, that the connection cables of the junction box do not run between laminate and mounting rails.
Modules 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.
Ensure 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).
Unbalanced loads (e.g. snow overhangs, snowdrifts) which result in locally significantly increased loads must be removed or
avoided by technical measures.
Loads according to IEC 61215-2:2016 and UL 61730-2:2017 except for design loads lower than 1600 Pa which
do not fulfill the requirements of the standards. The test procedure is always according to IEC 61215-2:2016.
Design loads result from the safety factor 1.5.

2.4 Electrical layout
Module Selection
For detailed key electrical data, please refer to the actual data
sheet referring to the relevant Module (available at www.qcells.
com).
For 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.
Please 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.
Take into account all possible operating situations and all
relevant technical norms and regulations when designing the
system. It has to be ensured that the maximum system voltage,
including all necessary safety margins, is not exceeded.
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).
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:
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 manufacturer 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 Qcells 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-
currentcarrying metal equipment to the appropriately sized
equipment grounding conductor (EGC) or racking system that can
be used for integrated grounding.
Qcells 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
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 Qcells 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 Qcells
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 Qcells
modules, however each combination module / racking system

8 Maintenance and cleaning
Qcells 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
The PV system has to be inspected regularly by certified
personnel
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.
Inspections have to be performed especially after extraordinary
events (e.g. storm, hail, high snow loads etc.)
During 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!
Only clean modules that have cooled down.
Do not carry or wear any electrically conductive parts.
WARNING!
Risk of falling due to unsecured access!
Never access the installation area alone or without taking
adequate security precautions.
Please commission a trade specialist.
NOTE!
Module surface damage may occur!
Remove snow and ice carefully without force (e.g. with a very
soft broom).
Do not scratch o dirt.
Module cleaning has to be done by qualified personnel
according 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
components, e.g. cable, connector, silicone)
■no abrasive materials.
NOTE!
Dust and dirt are abrasive materials!
The situation for each individual project (or type of dirt) must
always be professionally evaluated.
Wrong cleaning may cause damages such as, but not limited
to, damages to the glass surface (e.g. scratches) and AR
coating, 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.
Note! Module damage may occur!
Do not clean modules with water if there is a risk of
frost.
