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.
