General and transport tips
The installation must only be carried out by qualifi ed personnel The entire information in these instructions is intended
exclusively for such qualifi ed personnel. Only the supplied material should be used for the installation. Prior to starting
installation and operation of the solar collector system, please inform yourself about applicable local standards and re-
gulations . It is recommended that a TGSKR-E carrying strap be used for transporting the collector . The collector must
not be lifted direct at the tube copper pipes or connection parts . Ther is a danger of damage . The transport protection
used on the corners and edge of the glass must only be removed immediately before the collector is inserted into the
mounting system. Avoid impacts and mechanical infl uences on the collector, particularly on the solar glass, rear panel
and the pipe connections .
Statics
The collectors must only be mounted on suffi ciently load-bearing roof surfaces and substructures. It is imperative that
the static load bearing capacity of the roof or substructure is checked in terms of local and regional conditions prior
to installation of the collectors by the customer, if necessary with the involvement of a structural engineer. Particular
attention should be paid to the quality of the (timber) substructure in terms of the stability of the screw connections
necessary for fastening the collectors. To prevent damage to the roofi ng in the event of considerable loads, the use of
metal reinforcements such as metal bricks is recommended . The inspection of the entire collector structure according
to EN 1991-1 Parts 3 and 4 NA or as per the applicable country-specifi c regulations is particularly important in areas
with heavy snowfall or in areas exposed to high wind speeds . The assessment should also take into account any par-
ticular circumstances at the place of installation (foehn wind, air jets or eddy formation etc.) which can lead to increa-
sed loads . Snow catchers are to be installed at a maximum distance of 0 .5m from the upper edge of the collector (the
collector should not function as a snow catcher) . It must be ensured for the selection of the installation location that
the maximum loads are neither exceeded by snow nor wind forces. Basically, the collector arrays must be installed so
that any possible accumulation of snow is prevented from reaching the collectors by snow barriers (or by special forms
of installation). The collectors may not be installed at the edge of the roof (e/10 marginal zones on areas of roofi ng
are to be complied with pursuant to EN 1991, but they must be at least 1m). The upper edge of the collector may not
project beyond the roof ridge .
Pitched roof mounting tips:The installation of a collector array is an intervention into a (existing) roof . Roof co-
verings such as bricks, shingles and slates, especially converted and inhabited loft spaces or roofs with less than the
minimum slope (with regard to the covering) require building measures e.g. underroof membranes, as protection
against water penetration caused by wind pressure and driving snow .
Flat roof mounting tips: For larger collector arrays we recommend installing the collectors on a special supporting
structure . Alternatively installation is possible without penetrating the roof membrane by using concrete ballast with
guys. The collectors are mounted on concrete blocks. Rubber mats should be used with a certifi ed coeffi cient of fric-
tion if necessary to increase the adhesion (static friction) between the roof and concrete ballast blocks and to prevent
damage to the roof membrane .
Note for canopies: The installation of a panel represents an intervention in an (existing) load-bearing system (wall
or support structure) . It is absolutely imperative that you penetrate any initial non-loadbearing structures (thermal
insulation, façades etc.) and that you securely anchor the panels directly in the loadbearing masonry or on the exis-
ting support structure. When designing an appropriate anchoring or fi xing system you must take account of the load
transfer point of panels mounted on canopies (note: the bending moment in the fi xing elements as a result of moun-
ting away from the support structure must be included in the calculations.). In addition to the statically required fi xing
elements, the infl uence of the panels on the entire system (supporting wall or support structure) must be taken into
account. If required, reinforcements need to be arranged at the load application points, with panels mounted as cano-
pies, in façade mounting posts or in the masonry.
Lightning protection / Equipotential bonding of the building
As per the stipulations of Lightning Protection Standard EN 62305 Parts 1 to 4, the collector fi eld must not be con-
nected to the building's lightning protection. Beyond the scope of validity of this standard, country-specifi c 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 installations on top of existing metal substructures, an authorised and qualifi ed 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/fi xtures must be connected to the main equipotential busbar in accordance with EN 60364 and/or country-
specifi c legislation by an authorised and qualifi ed electrician.
