The Azimuth describes the collector area's angle of deviation from the south (northern
hemisphere) or from the north (southern hemisphere). It is 0° (in the northern hemisphere)
when the area is exactly oriented to the lunchtime position (zenith) of the sun.

PV*SOL detects whether the system is in the northern or southern hemisphere from the
climate data record, which includes the degree of latitude.
The Tilt angle (inclination) describes the angle between the horizontal and the module
surface. It is 0° when the modules lie flat on the ground and 90° when they stand
vertically.
The radiation processor calculates the irradiation to the tilted surface from the inclination
and orientation.
-> How to proceed:
1. Select from
• Fixed inclination
• Single axis tracking: Enter a tilt angle. The azimuth automatically tracks the
sun.
• Dual axis tracking: The module is rotated at all times so that the solar
radiation strikes the module vertically.
2. If applicable, enter the orientation and tilt angle.
The resulting annual irradiation, taking shading into account, is shown in
Irradiation.
3. Click on Graphic to see the irradiation [kWh/m²] over the course of a year and the
radiation annual duration curve [W/²].
