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.
Modules must be securely attached to the mounting
structure. For clamping system installation, 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 60 cm (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.
AEG GLASS-GLASS MODULE INSTALLATION MANUAL
AEG PV modules can be installed with:
• frame mounting holes and bolts – See 3.2. 1 "Bolting"
• pressure clamps – See 3.2.2 "Clamping"
• insertion systems - See 3.2.3 „Insertion systems"

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 M6 bolts (for 11,5 mm
holes) / M8 bolts (for 14 mm holes) and a tightening
torque between 8-12 N•m (for M6 bolts) and 16-23 N•m
(for M8 bolts) are suggested. When using frame height
of 30 mm it is recommended to select a fastner with
length L ≤ 20 mm while mounting the modules with
bolts. Please check with your system designer or installer
the specific load calculations for your plant; please refer
to the Annexes at the end of the manual for information
on your specific product series.

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
the Annexes at the end of the manual for information on
