Notice
In the following diagrams, the lead flashing is blanked out (the lead flashing has to be placed before the
mounting clamps are mounted!) for better understanding.

1. Mount the bottom Solrif® batten at a distance of the height of the wedge plank plus 30 mm from the upper edge of the
bottom row of tiles, observing Chapter
„Rules for Mounting Solrif® Battens“.

5�3�2 Calibrating and Placing the Substructure
“Calibrating” is the fitting and alignment of the PV array within the remaining roofing. For definitions of the in- dividual
measurements, see Chapter „Dimension of PV Array and Module Mounting Pitches“ on page 12, for the placement of the
reference points, see also Chapter
„Preparing the Roof”.
3. As shown on the picture below. The evenness of the roof needs to be checked and corrected, if necessary. Respecting the
stated conditions below is mandatory.
4. Check whether the roof fulfils the following requirements across the entire PV array:
A ≤ 1 cm
A / (2 × B_S) ≤ 0.5 %
If the requirements are not fulfilled:
5. Even out the troughs by nailing on pieces of wood (shifts).
