PV direct installation with the S-5!® PVKIT® on a new building in Mainz
For a new building project in Mainz, a photovoltaic system was installed directly on a standing seam roof – namely completely without rail systems. Our customer TA Solar relied on the innovative S-5!® PVKIT®, which was specially developed for rail-free direct mounting.
Thanks to this solution, the framed PV modules could be mounted directly onto the standing seam profiles. The result: a easy, stable and visually clean assembly, which significantly reduces both material and time expenditure.
A particular added value for this project was the direct support from the S-5 team! On-site. Together with the installer TA Solar, the installation was precisely planned and efficiently implemented. This close collaboration ensured that all work steps were optimally coordinated and the project could be completed quickly.
Challenges and solutions:
-
Requirement: Fast installation with simultaneous high roof load reduction.
-
Solution: Use of the S-5!® PVKIT® for rail-free direct mounting, resulting in weight savings of up to 80% compared to conventional systems.
-
Requirement: Secure hold on standing seam profiles without roof penetration.
-
Solution: Use of original S-5!® mini clamps, which ensure gentle and standard-compliant fastening.
Project results:
-
Significantly shortened assembly time thanks to pre-assembled components
-
Clean roof look without protruding rail systems
-
Optimal wind suction reduction through roof-parallel module position
-
Durable fastening with tested original parts
This project in Mainz is an example of how the combination of innovative fastening solutions and close partnership with installers highest efficiency and quality can be reached.
