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 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 
adequate 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 
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!

Note! Module damage may occur!

 

Ä

Do not clean modules with water if there is a 
risk of frost.

 

Ä

Free the substructure from any dirt and debris 
(leaves, bird nests, etc.).

 

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 
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.
