Additional third-party grounding devices:
AEG solar modules can be grounded using third-party
grounding devices. It is required that these devices are
certified for grounding solar modules and are installed
according to the manufacturer‘s instructions.
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
affected 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 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.
