Loading Cases

In the case of azimuthal tracking systems, rotation around the vertical axis (y orientation angle) is not relevant for the loading of the structure. The geometry of the structure is mainly changed from the a orientation angle. The extreme positions of this movement must impose the loading cases that must be considered:

• Loading case 1: a = 67°, corresponding to summer solstice at noon;

• Loading case 2: a = 9°, corresponding to winter solstice at sunrise.
