INSTALLATION AND OPERATION MANUAL SOLAR MODULES DUO-G5.X – Q CELLS
21
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
Ä
The PV system has to be inspected regularly by certified
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 extraordinary
events (e.g. storm, hail, high snow loads etc.)
Ä
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!
Ä
Only clean modules that have cooled down.
Ä
Do not carry or wear any electrically conductive parts.
WARNING!
Risk of falling due to unsecured access!
Ä
Never access the installation area alone or without taking ade-
quate security precautions.
Ä
Please commission a trade specialist.
NOTE!
Module surface damage may occur!
Ä
Remove snow and ice carefully without force (e.g. with a very
soft broom).
Ä
Do not scratch off dirt.
Ä
Rinse dirt (dust, leaves, etc.) off with lukewarm water or use an
alcohol based glass cleaner. Do not use abrasive detergents
or surfactants.
Ä
Use a soft cellulose cloth (kitchen roll) or sponge to carefully wipe
off stubborn dirt. Do not use micro fleece wool or cotton cloths.
Isopropyl alcohol (IPA) can be used selectively to remove stubborn
dirt and stains within one hour after emergence.
Ä
Please follow the safety guidelines provided by the IPA man-
ufacturer.
Ä
Do not let IPA run down between the module and the frame or
into the module edges.
NOTE! Module damage may occur!
Ä
Do not clean modules with water if there is a risk of
frost.

6 MAINTENANCE AND CLEANING
Ä
Free the substructure from any dirt and debris
(leaves, bird nests, etc.).
Ä
Remove dirt with lukewarm water or alcohol based
glass cleaner, a broom, or a soft cloth.
Ä
Do not use surfactants, rotating brushes, scrapers,
or any high-pressure water cleaning equipment.
DANGER!
Risk of fatal injury due to electric shock!
Ä
Do not attempt to fix any problems yourself (e.g. glass cracks,
damaged cables).
Ä
Please contact an installer or Q CELLS Technical Customer
Service Department.
Ä
Do not disconnect modules yourself.
Ä
Please commission a trade specialist.
Ä
Dispose of modules in accordance with the local disposal
regulations.
6 FAULTS AND DEFECTS

5 GROUNDING
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
