Loads according to IEC 61215-2:2016 and UL 61730.
Rails must not be under the junction box.
MOUNTING OPTIONS REQUIREMENTS
All 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 = 40 mm and clamp depth = 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.
CL1a, CL2a, CL3,
CL6a, FB1, FB2
Ensure that module frame is fixed directly on the rail of the substructure (no spacer allowed
between the module and substructure).
CL1a At push test loads of 5400 Pa: The clamp position is variable in the given range but the distance
between the clamps along the long side of the module (span) must not be larger than 1250 mm.
CL1b Using of short mounting rails are permissible, if they overlap under the module less than
210 mm. Minimum clearance between frame bottom edge and roof top must be ≥ 35 mm.
CL1b, CL2b, CL3,
FB2, CL6c, CL6d A minimum support depth of 15 mm is required on the back side of the module.
CL5 The minimum required support depth on the module backside is 10 mm on long frame side and
15 mm on short frame side.
IP1 Ensure minimum support depth of 15 mm on the backside and 10 mm on the front side of the
module.
FB1, FB2 Use M8 corrosion-proof screws and washers (diameter ≥ 15.8 mm) for mounting slots (Detail A,
Fig.1). Mounting screws and washers should have the same material properties.
CL6c, CL6d Use of short mounting rails under the modules are permissible, if they do not touch the laminate
under load.

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
For detailed key electrical data, please refer to the actual data
sheet referring to the relevant Module (available at www.qcells.
com).
■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
Please follow the valid national guidelines for the installation of

Series Connection
Connection of modules in series is only permitted up to the
maximum system voltage as listed in the applicable data sheet of
all the relevant modules to be installed.
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

8 Maintenance and cleaning
Qcells solar modules are known for a long operating life and
minimal maintenance eort 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.
Free the substructure from any dirt and debris (leaves,
bird nests, etc.).
Note! Module damage may occur!
Do not clean modules with water if there is a risk of
frost.
