6. Adjusting the tilt angle
The tilt angle of the module can be adjusted in two ways:by adjusting the distance between the ground joints and
using elevation rails
of varying lengths. The elevation rail is available in two variants: 380 and 540. They vary in
length. See dimension A in Figure 2 and Table 1. Several different module tilt angles are possible for each elevation
(see Table 1).
