Mechanical Installation
Carry out the installation of the photovoltaic system
in such a way that the installed photovoltaic system
has a high resistance with respect to the environ-
mental influences affecting it (wind, rain, hail,
snow, etc.) ([21]).
aleo modules are suitable for an increased pressure
load of 5400 Pa and a suction load of 5400 Pa [28].
The permitted pressure load correlates to a surface
load of approx. 540 kg/m².
When mounting with clamps at an angle steeper
than 45°, we recommend using slip protection that
prevents the modules from sliding out of their origi-
nal position. Locally applicable regulations may, if
necessary, require the use of slip protection.
Avoid direct contact of the glass surface with the
supporting structure during installation.
In fixed installations, avoid movement of the base
frame onto which a module has been installed.
Only use installation material that:
is stable and corrosion-resistant
prevents corrosions on the solar modules ([32]).
NOTICE
Do not under any circumstances drill extra holes into
aleo modules or their frames.
RECOMMENDATION
Information on using anti-theft protection with the need
for holes can be found in Ch. 5.10, 'Anti-theft
protection'.
The following information applies to the modules as long as
the product-specific information for the respective module
type does not include any instructions to the contrary.
NOTICE
Arrange the aleo modules in such a way that the
rear junction boxes remain as dry as possible and
that no water can accumulate in the sockets.
Only install aleo modules:
vertically (the short module edge is horizontal,
the junction box is at the top)
-OR-
horizontally (the long module edge is
horizontal).
Details about the mounting options for aleo modules can be
found in Ch. 9, 'Mechanical Mounting Details'.
7.1.
Visually attractive roof installation
In order to install the modules on a roof in a visually attractive
manner, please observe the information in Ch. 5.8, 'Visually
appealing installation' during planning.
7.2.
Types of installation
Framed aleo modules may be installed in the following ways:
clamping
bolt installation
lay-in installation
7.3.
Support area
NOTICE
If supports are necessary, ensure that the contact
surface is at least 70 mm² per support.
7.4.
Spacing and clearances
7.4.1.
Spacing between the module frames
NOTICE
Allow for a minimum spacing during installation.
This prevents the occurrence of mechanical stress
resulting from thermal expansion.
When mounting at with spacing between the
module frames
leave a gap of at least 3 mm between
individual module frames.
When using flush mounting
ensure for an expansion gap of 20 mm, at the
least every 7 m.
aleo solar recommends mounting at intervals.
Also note Ch. 5.8, 'Visually appealing installation'.
Please also observe the guidelines provided by the
mounting system manufacturer as these may
stipulate the use of larger intervals.
