Protective Grounding
Ä
The modules must be grounded in accordance with the
local statutory regulations.
Functional grounding
•
For installations located in tropic regions (between 23.5° N
and 23.5° S) with a module tilt of < 5°, functional
grounding at the negative generator connection on the
DC side must be implemented.
Ä
Ensure that the difference of potential between the
negative generator connection and the PE(N) of every
MPP tracker of the respective inverters is 0 V.
Ä
Follow the directions of the inverter manufacturer.
Ä
Only use inverters which include lincensed grounding
kits.
Ä
Functional grounding has also to be implemented in
installation sites with increased salt content in the air
(e.g. close to the sea).
5 GROUNDING
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.
6
FAULTS AND DEFECTS
Ä
Do not disconnect modules by yourself.
Ä
Please contact an installer or Q CELLS Technical
Customer Service Department.
Ä
Dispose of modules in accordance with the local disposal
regulations.
7 DISPOSAL
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 extraor-
dinary 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 adequate 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
manufacturer.
Ä
Do not let IPA run down between the module and the
frame or into the module edges.
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, scrapers,
or any high-pressure water cleaning
equipment.
NOTE
! Module damage may occur!
Ä
Do not clean modules with water if there
is a risk of frost.
