Flat roof (bitumen roof), terrace (free standing)
⚫ Choose a suitable location for the installation of the solar system, free from
obstacles and with enough space to allow you to adjust the tilt angle (if necessary).
⚫ Be at least 2 people to lift and mount the solar modules.
⚫ The mounting angle (30°, 35°, 40°), the orientation (west, south, east) as well as
the geographical location influence the yield of the balcony power plant.
⚫ The statics of the roof for the photovoltaic system must be checked by the customer.
The photovoltaic system can be installed up to a roof height of 9m, a sea level of max.
350 m and a roof pitch of 45°.
⚫ We recommend a distance of 1.25 m to fire walls of adjacent buildings (e.g. row
houses). For more detailed requirements for your federal state, refer to your state
building code (LBO).
⚫ Make sure that national and site-specific building regulations, occupational safety
and accident prevention regulations, standards and environmental protection
regulations are observed.
Note: In the case of a flat or bitumen roof fastening, the use of screws is not
recommended. The screws would damage the seal of the roof and the roof could leak.
Weighing down the module support
⚫ The solar module (up to 19kg) should be positioned at ground level or centered on
a flat roof.
⚫ Suitable is a bracket for mounting on bitumen, concrete, in the garden on the lawn
or terrace.
⚫ The weighting is calculated according to the terrain IV (urban area), where at least
15% of the area is covered with buildings, the average height of which exceeds 15m,
and may differ for other heights or terrain structures.
⚫ In case of installation on a flat roof, the top edge of the building should be lower
than 15m and the photovoltaic system should be at least 1.25m away from the
neighbor's roof surface. The maximum slope of the ground may be 5°.
⚫ One concrete slab should weigh 9kg.
⚫ Check whether the statics of the installation site are suitable for the photovoltaic
system. Technaxx Germany does not assume any liability for the suitability of your
installation site.
