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:
•
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 compo-
nents 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, only
for the glass surface, an alcohol-based glass cleaner. Do not use
abrasive detergents or surfactants for any part of the panel.
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.
