2. SAFETY
2.1 General safety
All AEG PV modules should be installed according to
all local and national applicable standards, codes and
regulations. Only qualified personnel should install
the solar modules. Installers bear the risk of all injury
that might occur during installation including, without
limitation, the risk of electric shock. Check and follow
all safety precautions specified even for the other
components of the system.
Look for any visible damage to the package or the
product itself. Double-check the order information
and the product nameplate to ensure the products
are of the ordered type. Should you find any problems,
contact the shipping company and / or your supplier as
soon as possible before attempting product installation.
2.2 Handling safety
Please observe the below indications when handling
AEG solar modules:
Store the pallets in a ventilated, dry location until
installation. Do not open the module boxes during
storage or transportation. Inappropriate transport and
installation may void the warranty.
Do not apply paint or adhesive to module top
surface.
Do not use mirrors or other magnifiers to
artificially concentrate sunlight on the modules.
Do not expose back sheet foils directly to sunlight.
Do not attempt to disassemble the modules

4
AEG GLASS-GLASS MODULE INSTALLATION MANUAL GD202008 V1-20EN
Do not remove any attached nameplates or
components
Do not exceed the maximum stapling limitation of 2
pallets (standard packaging for shipment).
After unpacking, the modules should be laid
horizontally. Do not incline or stack the modules.
Do not pile up modules without protections to prevent
scratches to the glass and frame. Should the modules
need to be piled, they need to be separated by special
paper or plastic angles.
Do not scratch or damage the module surface.
Do not drill holes in the frame as it may compromise its
strength, cause corrosion and void the warranty.
Do not use the junction box and cables as a grip.
Do not drop the module or allow objects to fall on the
module.
Do not place any heavy objects on the module to avoid
glass breakage.
Do not stand or step on the module.
Do not set the module down hard on a surface.
Do not attempt to repair a module with broken
glass or torn backsheet and do not use it as
contact with any module surface or the frame
could cause an electric shock.
2.3 Installation safety
Installing solar photovoltaic systems requires
specialized skills and knowledge. Photovoltaic solar
modules are designed for outdoor use, and may be
ground mounted as well as mounted on rooftops,
vehicles or boats. The proper design of support
structures is a responsibility of the system designer
and installer. When installing the system, abide with
all local, regional and national statutory regulations.
Keep children away from the installation site and
during transportation and installation of the electrical
equipment.
Cover the module completely with a dark opaque
material during installation to prevent electricity
generation.
When working with modules without any cover, the
safety regulations for live electrical equipment need to
be followed. Use only equipment, connectors, wiring
and support frames suitable for use in a solar electric
installation.
Do not wear metallic rings, watchbands, ear,
nose or lip rings or other metallic devices while
installing or troubleshooting photovoltaic
systems in order to avoid electric shock.
Do not disconnect modules under load to avoid
electrical arcs.
Contact with electrically active parts of the modules,
such as terminals, can result in burns, sparks and
lethal shock whether or not the module is connected.
Do not insert electrically conductive parts into the
plugs and sockets.
Do not install solar modules and wiring with wet plugs
and sockets.
Exert extreme caution when carrying out any work on
the wiring. High contact voltages can generate in the
inverter when it is isolated.
Abide with the safety regulations for all the other
components used in the PV system, including wiring
and cables, connectors, charging regulators, inverters,
storage batteries and rechargeable batteries, etc
One individual module may generate DC
voltages greater than 30 V when exposed to
light of any intensity. Contact with a DC voltage
of 30 V or more is potentially hazardous. The series or
parallel connection of the modules increases the
voltage or electric current respectively. The electrical
characteristics are within ±3 % of the indicated values
of Isc, Voc and Pmax under standard test conditions
(irradiance of 1000 W/m², AM 1.5 spectrum, and a cell
temperature of 25 °C/77 °F ). Under normal conditions,
a photovoltaic module is likely to experience conditions
that produce more current and/or voltage than
reported at standard test conditions. Accordingly, the
values of Isc and Voc marked on the module should be
multiplied by a factor of 1.25 when determining
component voltage ratings, conductor current ratings,
minimum factor of fuse sizes, and size of controls
connected to the PV output.
2.4 Fire safety
AEG PV modules are tested according to the provisions
of IEC EN 61730 Directive with Application Class A. Fire
safety has been rated as Class C.
!
Please be aware that rooftop installations can
aect the fire safety of a building. Rooftop
installations should be placed over fire resistant
roofs only; fire class A is recommended. Only fire-
resistant components should be used for rooftop
installations.
Do not install the solar panels in the proximity of
sources of flammable gases and vapors or open flames.

3. INSTALLATION
3.1 General remarks
AEG PV modules should be installed in a location
where they can receive the maximum amount
of sunlight throughout the year. In the Northern
Hemisphere modules should face south, while in the
Southern Hemisphere they should face north. The
modules should not be shaded at any time by trees,
antennas, cables, houses etc. If a module is shaded
or even partially shaded, it will fail to perform at ideal
conditions and this will result in lower power outputs.
AEG PV modules connected in series should be
installed at the same orientation and tilt angle. Dierent
orientations or angles may cause a loss of power
output due to the change in sunlight exposure. Dust
building up on the surface of the modules can impair
module performance. Solar Solutions recommends
installing the modules with a tilt angle of at least 10
degrees, making it easier for dust to be washed o by
rain. When designing the final layout of the modules in
a photovoltaic system, keep suitable access space to
allow easy maintenance and inspection works. Provide
adequate ventilation under the modules for cooling.
Always use structures and materials specifically
developed and certified for photovoltaic module
installation.
AEG PV modules must be installed and stored in the
following conditions:
Operating temperature From -40°C To +85°C
Storage temperature From -40°C To +85°C
Humidity Below 85% R.H.
!
Do not carry out the installation in high winds
and prevent the falling of objects from the roof.
Secure the work area so that nobody on or
beneath the roof can be injured.
When installing a module on a roof or building, please
ensure that it is securely fastened and cannot fall as a
result of wind or snow loads.
The modules should not be immersed in liquid.
Corrosion risk incurs if the module is exposed to salt
(i.e. marine environments) or sulfur sources. The
installation distance of the modules to sea water
or lakes should therefore be at least 500 mt unless
otherwise specified. The module should not be exposed
to unusual chemical loads. For fire safety indications,
please see 2.4 “Fire safety”.
Protect the solar modules from overvoltage, e.g.
voltage peaks of battery charges, generators, etc. If the
module has to be connected to a storage battery, all
precautions as prescribed by the battery manufacturer
should be taken into account
3.2 Mechanical installation
AEG PV modules can be installed in either landscape
or portrait orientation. In choosing the orientation,
please keep in mind the internal PV module bypass
diode configuration to ensure the optimum electrical
behavior from any potential shading over the module.
Ensure modules are not subjected to wind or snow
loads exceeding the maximum permissible loads, and
are not subject to excessive forces due to the thermal
expansion of the support structures. Ensure that
the drainage holes of the PV module do not incur in
blockage. Do not dismount, drill or modify the frame or
any other part of the PV module, as this will void the
warranty. Please contact our Technical Service should
you need any clarification concerning the installation
instructions.
If the modules are unpacked but not installed
immediately, please wrap the connectors to prevent
damage caused by wind or rain. Do not use any
lubricant on connectors and do not remove the
waterproof rubber rings from the junction box or
connectors.
The module mounting structure must be made of
durable, corrosion-resistant and UV-resistant material.
A tested and certified mounting structure approved for
the considered system design should be used. Ensure
the installation method and mounting structure are
able to withstand the load conditions. Always observe
the instructions and safety precautions of the mounting
structure. In regions with heavy snowfall in winter,
select the height of the mounting structure so that the
lowest edge of the module is not covered by snow at
all times. In addition, ensure that the lowest portion of
the module is high enough not to be shaded by plants,
trees or dirtied by soil.

6
AEG GLASS-GLASS MODULE INSTALLATION MANUAL GD202008 V1-20EN
Modules must be securely attached to the mounting
structure. For clamping system installation, the
recommended maximum compression for each clamp is
2900 PSI (20 Mpa) in order to avoid potential damages
to module frames; follow the instructions provided by
the clamping system supplier.
!Avoid exposing the frame to lateral tension and
pressure, as this might crush the glass or spark
a fire. Consider the linear thermal expansion of
the frames: the recommended minimum distance
between two modules is 1 cm.
For ground-mounted systems, the minimum distance
recommended from the ground to the module bottom
is at least 60cm (24 inches).
For roof-mounted systems, always ensure the suitability
of the roof construction before installing the modules
on a roof. In addition, any point of roof penetration
required to mount the modules must be properly
sealed to prevent leaks.
Provide adequate ventilation under the modules in
conformity to local regulations. A minimum distance
of 10 cm between the roof plane and the frame of
the module is generally recommended. Never allow
modules to overlap or to exceed the rooftop size.
When installing a module on a pole, select a pole and
module mounting structure that will withstand the
anticipated wind load and snow load for the area.
AEG glass-glass PV modules can be installed with:
• frame mounting holes and bolts – See 3.2.1 “Bolting”
• pressure clamps – See 3.2.2 “Clamping”
3.2.1 Bolting
Always observe the instructions and safety precautions
of the mounting system. Modules must be securely
fixed to the mounting system (support rails) using the
provided mounting holes. There are 4 (four) mounting
holes placed to optimize the load handling capability of
the module and to secure it to the supporting structure.
If increased wind or snow-loads are expected, the
additional mounting holes provided should be used.
It is recommended to use corrosion proof (stainless
steel) hardware. Stainless steel M8 bolts and a
tightening torque of 15-20 N • m are suggested. Please
check with your system designer or installer the specific
load calculations for your plant and refer to figure 3 and
figure 5 for details.
Figure 3: Bolting
3.2.2 Clamping
Installation using pressure clamps can be done on both
sides of the module frame. Use at least 4 (four) clamps
per module, two on each long side of the module (for
portrait orientation) or two on each short side of the
module (for landscape orientation). Depending on the
local wind and snow situation, additional clamps might
be required to ensure the module is able to withstand
the load. Module clamps should not come into contact
with the front glass and should not deform the frame.
Ensure to avoid shadowing from module clamps. Please
refer to figure 4 and figure 6 for details.

3.2.3 Loading capacity
The PV module‘s load resistance is rated as:
Wind load: 2400 Pa / Snow load: 5400 Pa.
Please note this could vary according to the dierent
mounting systems and configurations.
For standard conditions, low loading capacity applies:
AEG modules are tested under a maximum positive
pressure of 2400 Pa, and negative pressure of 2400
Pa; they are designed to meet a maximum positive
pressure of 1600 Pa, and negative pressure of 1600 Pa.
For extreme conditions (e.g.: heavy snow), high loading
capacity applies: AEG modules are tested under a
maximum positive pressure of 5400 Pa, and negative
pressure of 2400 Pa; they are designed to endure a
maximum positive pressure of 3600 Pa, and negative
pressure of 1600 Pa. Both low and high load design
were tested with a safety factor of 1.5 times.

3.3 Electrical Installation and Grounding
3.3.1 General remarks
Modules electrically connected together in a series/
parallel configuration generate DC electrical energy,
which can be converted to AC by mean of a solar
inverter. When modules are connected in series, the
total voltage is equal to the sum of individual voltages.
For applications requiring high currents, photovoltaic
modules can be connected in parallel; the total current
is equal to the sum of individual currents.
The resulting PV system can then be connected to
the local utility grid system. As the policies of local
utilities and technical rules concerning the connection
of renewable energy systems to power grids vary
from region to region, please consult a qualified
system designer or integrator to design a system
compliant with the related directives. Permits are
normally required for installing a PV system and the
utility must formally approve and inspect the system
before its connection to the grid can be accepted. The
connection of the inverter to the grid needs to be done
by a competent, authorized company. The electrical
installation of the PV system must be carried out in

8
AEG GLASS-GLASS MODULE INSTALLATION MANUAL GD202008 V1-20EN
accordance with the respective National Electrical
Codes or applicable National Regulations.
3.3.2 Electrical installation
To avoid mismatch, power loss or damage to the PV
system, do not use dierent module types within the
same circuit.
The modules are fitted with two pre-assembled
sunlight resistant, isolated cable leads, which end with
PV fast connectors for the electrical connection of
the system (positive [+] and negative [-] terminals).
Connectors are Multi-Contact (MC4) or Multi-Contact
compatible (MC4-compatible). Cables and connectors
must not be removed or cut o.
Refer to the electrical parameters reported on
the label of the module when selecting the size
of the cables connecting the module strings to
the solar inverter. For electrical design considerations,
when determining component voltage ratings,
conductor current ratings, fuse sizes and the rest of
electrical hardware connected to the module strings,
the values provided on the module label or on the
related datasheet should be multiplied by a factor of
1.25 for Short Circuit Current (Isc) and Open Circuit
Voltage (Voc).
Please consult rated local wiring regulations to
determine system wire size, type, and temperature
rating of conductors to be connected to module
connectors.
The maximum system voltage is 1000 volts or 1500
volts depending on the product type. Please check the
product label and datasheet accordingly.
The maximum number of series connected modules
depends on system design, the type of inverter
used and environmental conditions. Always ensure
that the modules are assembled with the appropriate
string fuse for circuit protection based on the maximum
series fuse rating of the module and local electrical
installation codes.
There is no specific limitation on the number of
modules that can be connected in parallel; the number
of modules is determined by system design parameters
such as current or power output.
To prevent the cables and the connectors from
overheating, the cross section of the cables and the
capacity of the connectors must be selected to suit the
maximum system short circuit current. The
recommended PV wire should have a cross section of
minimum 4mm2.
3.3.3 Grounding
Please refer to the respective National Electrical
Code requirements and standards for safety-related
grounding of racking system and/or module frames.
AEG PV Modules use an anodic oxidized aluminum
frame; modules should hence be connected to the
equipment grounding conductor to prevent electrical
shock.
The frame rails have pre-drilled holes marked
with a grounding sign. The grounding holes
should be used for grounding purposes only and
not for module mounting.
Grounding methods:
1) Use stainless steel M8 bolt and washer to bond
the ground wire and aluminum frame through the
grounding hole (see figure 8) with a tightening torque
of 3-7N • m. It is recommended to use a 4-14 mm2
(AWG 6-12) exposed copper wire as ground wire.
Fig.7 Grounding method with M8 bolt and washer
2) Use of grounding clamps
We recommend the use of SolKlip Grounding
Clip Assemblies 1954381 for safety purposes. The
grounding clip assembly consists of a slider, base, and

uninsulated copper wire sizes 10 or 12 AWG.
Fig.9 SolKip Grounding Clip
3) 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
a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 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.
