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 system should be inspected by an installer annually
to check the following:
• all system components sit securely and are corrosion
free.
• the connection is secure and all electrical components
are clean and undamaged.
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.
Clean the modules as follows:
NOTE!
Module surface damage may occur!
Remove snow and ice without force (e.g. with a very
Ä
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 tensides.
Use a soft cellulose cloth (kitchen roll) or sponge to
Ä
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.
Do not let IPA run down between the module and the
Ä
frame or into the module edges.
