General and transport information
The installation may only be carried out by a qualified professional. The instructions provided here are directed at qualified
professionals only. The supplied materials must be used for the installation. Prior to installing and operating the solar panel
system, familiarise yourself with the standards and regulations valid at the site in question. We recommend that you use
a carrying strap to transport the solar collector. You must not lift the solar collector by its connections or screw threads.
Do not jolt the collector or allow parts of it to be affected by mechanical factors. This is particularly important for the glass,
rear panel, and pipe connections.
Structural engineering aspects
The system may only be installed on a roof surface or substructure with a sufficient load-bearing capacity. The static load-
bearing capacity of the roof or substructure must be checked in accordance with local and regional stipulations at the site
prior to the installation of the panels, if necessary by means of the commissioning of a structural engineer. In particular,
it is important to check whether the quality of the (wooden) substructure is sufficient to enable the durability of the screw
connections for attaching the panel mounting apparatus. The onsite checking of the system (collectors and attachment
apparatus) as per EN 1991 and/or country-specific legislation is particularly important in areas prone to heavy snow or
high winds. All features of the installation site (foehn wind, venturi effect, vortex formation etc.) that might result in higher
stresses at the site in question must be investigated.
Information regarding sloping roofs: The installation of a collector field is carried out on a (preexisting) roof. Roof clad-
dings such as tiles, shingle, and slate, attics with a special construction or that are used for residential purposes, and roof
pitches that are below the minimum recommended value require (in relation to the cladding) additional measures to be
carried out by the customer in order to protect against the penetration of water as a result of wind force and driving snow.
This might include sub-roof membranes, for example. To prevent overloading the roof cladding/joints (for hanger screws
and roof clamps), metal roofing must be used from a characteristic snow load of > 1.25 kN/m². When selecting the instal-
lation site, note that the maximum permitted loads must not be exceeded as a result of snow or wind forces. As a general
rule, collector fields must be installed in a way that allows snow to freely slide off. Any accumulations of snow as a result
of the use of snow guards (or the peculiarities of the installation site) must not be able to reach the panels. Snow catchers
must be installed 0.5 m above the top of the panels to ensure that the panels themselves do not act as snow arrestors. To
prevent inadmissible wind loads, the panels must not be installed at the edge of a roof (e/10 zones as per EN 1991, but
minimum gap of 1 m). In particular in the case of elevated structures, the top of a panel must not protrude above the roof
ridge. Panels must not be installed below a height transition so that it is not possible for excess loads to fall onto the panel
system from the higher level as a result of drifting or sliding snow. If, to solve this problem, snow catchers are installed
on the higher level, the statics of the higher level must also be checked.
Information regarding flat roofs: The installation of a collector field is carried out on a (preexisting) roof. Attics with a
special construction or that are used for residential purposes and roof pitches that are below the minimum recommended
value require (in relation to the cladding) additional measures to be carried out by the customer in order to protect against
the penetration of water as a result of wind force and driving snow. This might include sub-roof membranes, for example.
When selecting the installation site, note that the maximum permitted loads must not be exceeded as a result of snow or
wind forces. To prevent inadmissible wind loads, the panels must not be installed at the edge of a roof (e/10 zones as per
EN 1991, but minimum gap of 1 m). Panels must not be installed below a height transition so that it is not possible for
excess loads to fall onto the panel system from the higher level as a result of drifting or sliding snow. If, to solve this prob-
lem, snow catchers are installed on the higher level, the statics of the higher level must also be checked.In the case of
larger collector fields, we recommend that you mount the panels on a separate bearing structure made from steel profiles.
Attachment using concrete ballast blocks enables the system to be installed without penetrating the roof cladding. If the
panels are mounted on concrete ballast blocks, rubber underlays must be used to increase the static friction between the
concrete ballast blocks, thus preventing damage to the roof cladding.
Lightning protection/building potential equalisation
As per the stipulations of Lightning Protection Standard EN 62305 Parts 1 to 4, the collector field must not be connected
to the building's lightning protection. Beyond the scope of validity of this standard, country-specific legislation must be
observed. A safety gap of at least 1 m from any adjacent object that may be conductive must be left. In the case of instal-
lations on top of existing metal substructures, an authorised and qualified electrician must be consulted. To enable potential
equalisation of the building, the metallic conductor pipes of the solar circuit and all of the collector housing/fixtures must
be connected to the main equipotential busbar in accordance with EN 60364 and/or country-specific legislation by an au-
thorised and qualified electrician.
