Installation information

  • Built: mid-2016
  • Yield: 99,75 kW
  • Roof dimensions: 82.96 m long and 45.25 m wide
  • 2 roof surfaces with 4 module fields
  • Roof covering: membrane roofs
  • Wind and snow load zones: 2

The first S-Rock project was a collaboration between K2 Systems and its partner EWS together with its customer AS Projekte GmbH in Osnabrück. The PV system has supplied the company building of All Seasons Self Storage, which rents storage spaces to private and commercial customers, with an output of 99.75 kW since this summer. The large warehouse was ideal for the construction of a modern PV system to cover a large part of the electricity requirement with the help of solar energy.


"The installation is an exciting pilot project in two respects. Not only was the S-Rock System installed for the first time on this flat roof, but it was also planned using our new online calculation tool Base On", reports Rainer Ebenho, Project Manager at K2 Systems. The free Base On tool supports planning through current satellite imagery, intuitive drawing tools, as well as detailed reports and plans.

When the S-Rock System was presented in July at Intersolar in Munich, it demonstrated clear savings in working time, transport weight and volume.

The installer Mr. Robert Friesen of AS projects was also won over: "It was great fun to assemble the system. I personally think S-Rock is very well thought out and the first installation here in Osnabrück was intuitive and very easy to assemble – as if a lot of thought went into the design. I give the S-Rock a thumbs up! "

Also for Katharina David, Managing Director of K2 Systems, the S-Rock is particularly impressive thanks to the reduced assembly time of up to 30 percent.
