-
Generator width [mm] = R
hor
[mm] x number of module columns
-
Generator height [mm] = R
ver
[mm] x number of module rows
2. Include the outer frame profiles, as they have no further overlapping elements:
-
Generator width [mm] + 30 mm (15 mm right and left)
-
Generator height [mm] + 30 mm (top)
3. Include the flashings, as the case may be.
CAUTION
Misinterpretation of the number of mounting clamps in accordance with DIN 1055!
Damage to the roof structure and to the entire photovoltaic system.
Calculate so that the required number of mounting clamps in direct relationship to the given snow load and
wind zone are used.

-
If the demands of the structural design require it, set the mounting clamps “glass” in center between the
framing clamps (a given number of “glass” clamps will have to be spaced evenly at the corresponding
pitch.
TIP
Contact your Solrif
®
dealer in order to draw up an individual grid plan for the photovoltaic modules.
Space the mounting clamps 15 mm away from the upper Solrif
®
profile, so that the modules can be pushed
upwards and removed, if need be, for example for repair work.
