4. MAINTENANCE
4.1 General mainteance
If any problem arises, have them investigated by a
competent specialist; repairing works must be performed
by specialized and properly trained personnel only.
Improper maintenance can cause lethal electric shock
and/or burns.
Use appropriate safety equipment (insulated
tools, insulating gloves, etc.) when handling
modules.
For any electrical maintenance, the PV system must be
shut down first.
Do not touch live parts or cables and connectors.
Do not disconnect the grounding when doing system
maintenance works.
We recommend the following maintenance in
order to ensure an optimum performance of the
module:
Check the electrical and mechanical connections every
six months to verify that they are clean, secure and
undamaged.
Check that mounting hardware, terminal screws and
grounding components are tightly secured and are not
aff ected by corrosion.
Replacement modules must be of the same type of those
to be replaced.
Modules generate high voltage when exposed to
sunlight. Cover the front surface of modules with an
opaque and not scratching material during maintenance.
Follow the maintenance instructions for all components
used in the system, such as support frames, charge
regulators, inverters, batteries etc.
4.2 Cleaning
Do not clean modules with broken glass or
exposed wiring. This can cause a general
electrical failure of the module or electrical shock
hazard.
Dirt and dust can accumulate on the glass surface of the
PV module over time, particularly in installations with low
inclination. This can cause a general decrease of power
output and also sedimentation on the lower edge of
the modules due to dirt accumulation. We recommend
AEG GLASS-GLASS MODULE INSTALLATION MANUAL
a periodic cleaning of PV modules to ensure maximum
power output, especially in regions with high quantity of
dust in the air or low precipitations as follows:
Under most weather conditions, normal rainfall is enough
to keep the PV module glass surface clean. Clean the
glass surface of the module as necessary and consider
that lower inclination requires higher cleaning frequency.
Always use water and a soft sponge or cloth for cleaning.
A mild, non-abrasive cleaning agent can be used to
remove stubborn dirt. High mineral content water is not
recommended, as it may leave residual deposits on the
module.
To avoid a possible thermal shock clean the modules
during early morning, when the module is still cold.
This is especially recommended in regions with hotter
temperatures.
In cold environments with snow do not try to remove the
frozen snow or ice from the module scratching on the
front glass. Only soft snow can be removed gently with a
soft brush.
Do not use abrasive sponges or aggressive tools that
could scratch the module surface; under no circumstance
should the dirt be dry removed, as this would cause
micro-scratches which could have a negative impact on
the module's performances.
4.3 Module End of Life
Please return any electrical equipment that you no
longer use to the collection points provided for their
disposal. Information concerning where the equipment
can be disposed of can be obtained from your local
authorities.
The wheelie bin symbol on the AEG product
labels means that the equipment shall be
disposed of as special waste in accordance to
the local regulations.
