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 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!

Ä
Never access the installation area alone or without taking
adequate security precautions.

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.
Use a soft cellulose cloth (kitchen roll) or sponge to carefully

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.
