Table: minimum vertical tilt angle of fascia to sensor normal
The values provided in the previous table are derived from evaluation of flat plates with constant
thickness and homogeneous material. Deviations from this situation may cause a change in
classification and the vertical tilt angle of fascia has to be increased.
