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 sha-
dowing 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. formation 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 speci-
fic data on optimum module positions in the pertinent
specialized literature. The calculation of the angle of
inclination can be based on the following formula:
angle of inclination = latitude of the positioning
locality – 20°
„ All modules of a photovoltaic generator are to be ali-
gned 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.
„ 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 mirrors
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 follow-
ing 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.
