8 Maintenance and cleaning
Qells 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
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
components are secure, undamaged and clean
Cleaning
WARNING!
Risk of injury due to hot and live modules!
Only clean modules that have cooled down.
Do not carry or wear any electrically conductive parts.
WARNING!
Risk of falling due to unsecured access!
Never access the installation area alone or without taking
adequate security precautions.
Please commission a trade specialist.
NOTE!
Module surface damage may occur!
Remove snow and ice carefully without force (e.g. with a very
soft broom).
Do not scratch off dirt.
Module cleaning has to be done by qualified personnel
according 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
components, e.g. cable, connector, silicone)
■
no abrasive materials.
NOTE!
Dust and dirt are abrasive materials!
The situation for each individual project (or type of dirt) must
always be professionally evaluated.
Wrong cleaning may cause damages such as, but not limited
to, damages to the glass surface (e.g. scratches) and AR
coating, 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.
Free the substructure from any dirt and debris (leaves,
bird nests, etc.).
Note! Module damage may occur!
Do not clean modules with water if there is a risk of
frost.
