2.2Requirements
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 4000m (13120ft) 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.
The solar modules are designed for the following applications: Operating
temperatures from 40°C to +85°C
(40°F to +185°F). Pull loads up to max. 2,400Pa and push loads up to max.
5,400Pa (see chapter “Mounting Options”). Installation using a mounting
structure for solar modules.
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).
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 Use customary clamps that satisfy the following
requirements: Clamp width: 40mm. Clamp height compliant with a 32mm frame
height. Clamp depth: 7-12mm. (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 affix the
module to the mounting frame.
Module Orientation Requirements Vertical or horizontal installation is
permitted.
Ensure that rain and melting snow can run off freely. No water accumulation.
Ensure that the drainage holes in the frame are not covered. No sealing.
Maintain the permissible angle of inclination. Minimum angle of inclination:
3° Inclination angles above 75° may be limited by

REQUIREMENTS
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 = 40mm and clamp
depth = 10mm. 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.
Ensure that module frame is fixed directly on the rail of the substructure (no
spacer allowed between the module and substructure).
A minimum support depth of 15mm is required on the back side of the module.
The minimum required support depth on the module backside is 10mm on long
frame side and 15mm on short frame side.
Ensure minimum support depth of 15mm on the backside and 10mm on the front
side of the module.
Use M8 corrosion-proof screws and washers (diameter 15.8mm) for mounting slots
(Detail A, Fig.1). Mounting screws and washers should have the same material
properties.

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.
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
electrical systems.
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.

8Maintenance 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! 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.
0°
NOTE!
Module surface damage may occur!
Remove snow and ice carefully without force (e.g. with a very soft broom). Do
not scratch off 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.
Free the substructure from any dirt and debris (leaves, bird nests, etc.).
