1.4 Solar modules
Positioning
Solar modules located in the northern hemisphere should face south. Use a compass to position the mod-
ules as precisely as possible. Due to the magnetic declination it may be necessary to turn the modules some
degrees away from the direction of the compass. In case of positive declination, turn the modules some de-
grees to the west, in case of negative declination, turn the modules some degrees to the east. See Fig. 4.

Fig. 4. The map illustrates the differences in magnetic declination in different parts of the world. Declination is
caused by the fact that the geographic north pole and the magnetic north pole are not located in the same place.
Depending on your location on the globe you must turn the solar modules away from the direction of the com-
pass. How much appears from the map.
Mounting
The solar modules must be mounted on a support structure.
When mounting the solar modules, make sure that the module frames overlap in order to allow for rain water
to run off.
For further information on the installation of solar modules, see installation and operating instructions for the
modules.
Tilt angle
For maximum utilisation of the solar radiation the tilt angle of the support structure can normally be adjusted
from 15° to 45°.
