General and transport instructions
installation and operation of the solar collector system, please inform yourself about the applicable local standards and
regulations. We recommend using an assembly crane for transporting the collector. The collector must only be lifted
on the collector, in particular on the solar glass, the collector rear panel and pipe connections.
Statics
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 through the involvement of a structural engineer. Particular
attention should be paid to the quality of the substructure in terms of the stability of the screw connections necessary
for fastening the collectors. The checking of the entire collector structure by the customer as per EN 1991-1 part 4
1m³ powder snow ~ 60kg / 1m³ wet snow ~ 200kg) or in areas exposed to high wind speeds (see table „Reactions to
(foehn wind, air jets or eddy formation etc.) which can lead to increased loads. As a rule, collector arrays must be ins-
talled such that any possible collection of snow is prevented from reaching the collectors by snow barriers (or through
special forms of installation). The distance to roof ridges/edges must be at least 1m.
Note: The installation of a collector array is an intervention into a (existing) roof; above all, converted and inhabited
loft spaces or roofs with less than the minimum slope (with regards to the covering) require additional measures by
the customer, e.g. sarking membranes, as protection against the penetration of water through wind pressure and dri-
ving snow. With larger collector arrays, we recommend installing the collectors on a special supporting structure made
of steel channels. Alternatively, it is possible to install the collectors without perforating the roof membrane by using
concrete ballast with guys. The collectors are mounted on concrete blocks. Rubber mats should be used if necessary
to protect the roof membrane against damage and to increase the friction between the roof and the ballast blocks. If
the dimensions of the concrete ballast blocks are adhered to as per the table below, no additional securing through
steel cables is required. If the total weight (total weight of the concrete ballast blocks and maximum possible snow
load) exceeds the static load bearing capacity of the substructure, a combination of lighter concrete ballast blocks plus
additional 5 mm steel cables (minimum tensile strength 1450N/mm²) can be used for securing.
