General installation options
WARNING
Mount the aleo modules in such a way that they can
withstand expected loads and weather-related in-
fluences. The supporting structure should be laid out
to support all locally expected snow and ice loads, as
well as wind forces (and suction forces).
NOTICE
In regions with especially high snow loads, supporting
measures on the rear side of the module are necessary.
Details on the mounting options for different loads can
be found in Ch. 9, 'Mechanical Mounting Details'. If you
have any doubts, please contact aleo solar Customer
Services (see Ch. 3.2, 'Product support').
5.7.1.
Roof installation
WARNING
Only install solar modules on roofs that have
a so-called fire-resistant surface according to
DIN 4102
1
[15], e.g. on roofs made of tiles,
metal, or shingle.
Do not, under any circumstances, install
solar modules on a thatch roof or on any
other kind of roof that has a so-called soft
surface, such as roofs made from straw or
wood shingles.
For rooftop installation, the following options apply:
On a flat roof:
Installation on supporting stands.
On a pitched roof, the above, plus:
on-roof installation
1
Hard roofing includes:
roofing that is listed as resistant against flying
sparks and radiant heat according to DIN 4102-4
roofing made from natural and artificial stones
according to the DIN 4102-A building material class
metal roofs according to the DIN 4102-B and
DIN 4102-B1 building material classes
various types of bitumen sheeting according to
DIN 52128, DIN 52130, DIN 52131 and DIN 52143
in at least double-ply
roofing covered completely with gravel filling (at
least 5 cm thick, 16/32 graining, specific surface
weight of at least 80 kg/m²))
roofing that is completely covered with mineral
panels
roofing with a test certificate according to
DIN 4102-7.
in-roof installation
More information on installation options can be found in
Ch. 7, 'Mechanical Installation'.
WARNING
Installation on roofs requires special sub-structures in
order to properly mount the solar modules. Ensure that
the sub-structure used, including all individual com-
ponents, adheres to the relevant laws, regulations,
guidelines, etc.
Evenness of the substructure
NOTICE
Construct the substructure in such a way that the
mounting surface is flat (even) for the modules.
This will make mounting the modules easier
and increase the durability of the mounted
modules against mechanical loads. It will also
help prolong the service life of the modules.
Avoid an arched or warped mounting surface at all
costs.
Even out height differences in the roof
construction with suitable additional
components.
More details about mounting options for aleo modules can be
found in Ch. 9, 'Mechanical Mounting Details'.
5.7.2.
Free-field installation
In a free-field installation situation, ensure that the lower
edges of the modules have sufficient clearance from the
ground. This serves to prevent soiling through spray water or
through blown/accumulated snow, as well as possible
shadowing by vegetation.
