8 MAINTENANCE AND CLEANING
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
Module cleaning has to be done by qualified personnel accord-
ing 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 compo-
nents, e.g. cable, connector, silicone)
•
no abrasive materials.
NOTE!
Dust and dirt are abrasive materials!
Ä
The situation for each individual project (or type of dirt) must
always be professionally evaluated.
Ä
Wrong cleaning may cause damages such as, but not limited
to, damages to the glass surface (e.g. scratches) and AR coat-
ing, 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.
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.
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.
