10. Installation
WARNING Injury
!
Take care when handling sharp edges. Wear suitable
safety equipment.
10.1 Installation location
DANGER Injury
!
When working on roofs, obser ve applicable
safety regulations.
Have all roof work carried out by a qualified contractor.
f Check the condition of the roof structure. Observe the static
calculation. If necessary, apply for planning permission with
the relevant authority.
10.1.1 Edge and corner areas
Roof edges, and here particularly the corners, are areas exposed to
strong winds and turbulence. Minimum clearances must therefore
be maintained.
A < 30 m
A ≥ 30 m
The width of the edge/corner area "R" is 1/8 of the narrower
roof side (A), but should be at least 1 m.
In residential buildings, office buildings and closed halls where
"A" is shorter than 30 m, the width of the edge area may be lim-
ited to 2 m.
The corner areas always have a square area with a side length
A/8.
Roof outlets
0.5 m < b ≤ 2 m
b > 2 m
Roof outlets include components that protrude more than 0.35 m
above the upper edge of the roof material at one or more points,
and that have a side measurement of at least 0.5 m. The width of
the associated edge area "D" is 1/2 of the longer component side
"b", but at least 1 m. The edge area may be limited to 2 m in width.
10.1.2 Standard snow loads for Germany
When installing the solar collectors, observe the required
minimum angle of inclination. This is based on the snow load zone
in which the collectors are installed. Your local Planning Office will
provide the relevant information. When making this calculation it
is assumed that the snow can slide off the roof unimpeded.

* In accordance with the relevant Planning Office
The standard snow load must also never be exceeded through the
formation of snow traps, snow drifts and ice.
10.1.3 Installed height
The collector frames are designed for a maximum installed height
of 20 m and a snow load of 1.25 kN/m². This corresponds to a
standard snow load of 1.2 kN/m².
