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:
Definitely align the solar module so as to avoid a
shadowing effect (even to a temporary or partial
extent: e. g. due to roof dormers, trees), since this
can lead to damage in the solar modules (e. g. forma-
tion of „hot spots“), failure of the PV generator and
loss of output.
Align the front of the solar module to the south.
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 positio-
ning locality – 20°.
All modules of a photovoltaic generator are to be
aligned at the same angle (horizontal as well as verti-
cal). In the event of angle deviations, separate fre-
quency converters are to be designated.
4 | Positioning guidelines
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.
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.
