Number of modules: 111 modules
Roof covering: trapezoidal metal sheet with 0.75 mm thickness
Roof pitch: 3° + 10° elevation
Partner: Solar Sky GmbH

Power generated is used for own consumption

The PV system with 111 solar modules and an inverter generates an output of 29.97 kWp and thus avoids 16,413 kg/year of CO₂ emissions.

Complete roof renewed in 9 days

‘First we renewed the roof with a 0.75 millimetre thick trapezoidal sheet to then install a PV system. The system, which was erected in March 2018, could be connected after only 9 days. The support from the K2 team worked out great, from the planning to the support during the installation. In this project, our 20 years of experience in the field of solar energy as well as our know-how from over 90 years in the construction industry paid off, ’ says Erik U. Oberänder, project manager Solar Sky GmbH.

‘The S-Dome Small system is particularly suitable on trapezoidal sheet metal roofs on which an additional elevation is to be achieved and on which the system is to be fixed in a highly bead-parallel manner. The system has an effective elevation angle of 13°, instead of 3° without the Dome System. This increases the performance and self-cleaning of the modules, ’ says Axel Klett of K2 Systems. Axel Klett has been actively supporting the K2 team since the beginning of the year and is in charge of the Northern Germany region.

System with horizontal solar modules

The 111 modules are laid out horizontally and clamped on the long side. The FlexClamp small clamp provides the appropriate hold between module frame and substructure.

S-Dome Small System

The mounting system consists of the MultiRail, which is fixed with self-drilling screws parallel to the beading.

On the MultiRail, the Dome S1000 small which is mounted by two MK2 insert nuts. Also the Dome SD is fixed by an MK2 and a cheese head screw.
