3 Positioning guidelines
In order to achieve the highest-possible annual energy
yield, we recommend positioning the module so as to
fulfill the following criteria:
You should mount the solar module in such a way that
it is not affected by shade (even temporary or partial
shade caused by dormers, trees or similar obstacles).
Shaded PV arrays can lead to PV generator failure and
losses in performance.
Prerequisite to installation on a flat roof is a hard
roofing seal per DIN 4102, Parts 4 and 7 – if there is
uncertainty about the roofing surface, please ask your
roofer.
When arranging modules in open field systems, suit-
able measures must be taken to ensure that readily
ignited organic materials (e.g. dry grass, hay) are
permanently removed from the vicinity of the system.
Position the front of the solar module, so that it faces
the Equator.

Select the angle of inclination according to the local
and structural factors (30° ± 15°). You will find spe-
cific data on optimum module positions in the perti-
nent specialized literature. The calculation of the
angle of inclination can be based on the following
formula: angle of inclination = latitude of the posi-
tioning locality - 20°.
All modules of a photovoltaic generator are to be
aligned at the same angle (horizontal as well as
vertical). In the event of angle deviations, separate
frequency converters are to be designated.
In order to ensure sufficient selfcleaning, the angle of
inclination must amount to at least 10°.
For optimized selfcleaning, a 15° minimum angle of
inclination is recommended.
Always ensure that the reverse side of the module is
well ventilated.
Attention!
Due to heat accumulation under the
modules there is an increased fire hazard
associated with rooftop installations
which do not meet the aforementioned
requirements.
You should mount the solar module in such a way that
it is not affected by shade (even temporary or partial
shade caused by dormers, trees or similar obstacles),
since this may lead to damage in the solar module,
such as formation of hot spots, PV generator failure
and losses in performance
Important note!
Take into account additional loads pro-
duced by the PV system's weight and
structural mount when carrying out the
structural analysis for the overall struc-
ture.
Modules must be mounted so that the rear of the
module does not come into contact with objects
behind it, even if a mechanical load is applied.
To avoid increased strain of the modules due to wind
load, it is necessary to observe minimum distances
from building boundaries according to DIN 1055-4.
A concentration of sunlight on the modules via mir-
rors or lenses is prohibited.
Avoid contact with salty water!
The crystalline solar modules made by Bosch Solar
Energy have been tested in accordance with the
following norms for their response to contact with
salty air:
– IEC 61701: 1995
– DIN EN 61701: 2000-08
– IEC 60068-2-52.
Please observe the test conditions indicated in the
norms when using the modules in salty air.
The system installer or operator must provide an
analysis of the building structure’s stability, deflec-
tion and loads.
Mount the modules on an adequately dimensioned,
permanently corrosion resistant, stable substructure.
The installation profiles are to be positioned in paral-
lel to one another.
The fastening points are to be aligned symmetrically
(see Figure 1).
