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.
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
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 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
17-23 N • m (for M8 bolts) are suggested. Please check
with your system designer or installer the specific load
calculations for your plant; refer to figure 3, figure 5 and
to paragraph 3.2.4 „Loading capacity" for details.

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.
