Ensure comprehensive fire protection:
The installation of on-roof systems may influence
the fire safety of a building. Improperly installed
systems can present even more of a danger in
the case of fire. Therefore, the modules of an on-
roof system must always be installed over a fire-
resistant surface. As the module is not regarded
as explosion-proof it must not be installed near in-
flammable gases and vapors e.g. close to gas con-
tainers, painting installations or gasoline stations.
Furthermore, the module must not be installed
next to open fire and flammable materials.
Make sure that the surroundings are suitable:
The module is designed for use in temperate cli-
mate. Make sure that after installation the module
is neither subjected to artificially concentrated sun-
light, immersed in water or continuously splashed
with liquids. If the module is subjected to salt or
sulfur, corrosion may occur. By all means make
sure that the module is not subjected to abnormal
chemical exposure. Therefore, due to the expect-
ed emissions, installation in the immediate vicinity
of production facilities is not recommended.
The correct installation situation
It is very important that the module fulfills the tech-
nical requirements of the overall system. There-
fore, care must also be taken that the module is
not exposed to any negative mechanical or electri-
cal influence from other system components. Only
connect modules with the same rated current in
series and modules with the same rated voltage
in parallel. The modules may only be operated at
the allowable system voltage; operation at a higher
voltage is not recommended.
The correct location for installation:
The module must not be installed as overhead
glazing or vertical glazing, e.g. on a facade. Beside
the module itself, the mounting system must also
be suited to the expected conditions at the loca-
tion of installation (snow, wind) and withstand them
easily. The bottom side of the module frame fea-
tures holes for draining precipitation water. Make
sure during installation that these holes retain their
function. When installing vertically the modules
junction box must face upwards.
Yield maintenance through optimal alignment
and inclination:
We advise you to familiarize yourself with the ap-
propriate alignment and inclination of the modules
prior to installation in order to ensure an optimal
system yield. The ideal conditions for the genera-
tion of electricity are accomplished when the sun
rays reach the generator surface perpendicularly.
With modules connected in series, make sure that
all modules have the same alignment and inclina-
tion in order to avoid performance losses.
