Technical overview
The Sunfix Bisun mounting system is a versatile sup-
port structure for the installation of solar modules on
flat roofs. It is individually prefabricated as a complete
kit. The basis of individual planning consists of data
from the existing roof structure and the structural
requirements (snow and wind loads, etc.) at the
installation site. Every system is provided with an
“system layouts” and “DC wiring plan” specific to your
system. These define the arrangement of the Sunfix Bisun elements, as well as the module cabling to the
inverter, all matched to suit your roof construction
and module arrangement.
Properties of the Sunfix Bisun mounting system
f
Permitted building height H ≤ 25 m
f
Permitted roof pitch ≤ 5° (flat roof)
f Module tilt 10°
f
Minimum size per module array 3 x 3 modules
f
Maximum size per module array 10 x 10 modules
f Standard static friction values:
Membrane roof with rubber mats (foil-laminated): µ ≥ 0.7
Divergent values are possible and can require more or less ballast.
f The required ballast is determined as part of the system planning and depends on system size, wind load
(location, building height), static friction value between system and roof, and presence of a parapet.
f
Flat roof insulation: We assume that the existing flat roof insulation is at least equivalent to the application
type DAA dh according to DIN 1408-10.
NOTE
The positional security of the system is ensured by
the dead weight and ballast. The measurement is
done according to Eurocode EN 1991. Nevertheless,
after extreme wind events, but at least once per year, the condition of the system must be checked,
since a shift of a few centimeters can never be
completely ruled out.
