Kirche Bettingen

The Protestant Reformed Church in Bettingen was rebuilt in 2021. The church fits well into the townscape thanks to the appealing architecture of the PV roof system, which is integrated almost over its entire surface.

What is the Solution?

MATCH Slate in Zero Reflect Fjord Grey was chosen for the roof of the newly built chapel in Bettingen.

Why Does it work?

The natural stone look of the solar modules integrates perfectly into the rural community and the lively effect of the church roof fits optimally with the diverse uses of the building. The new roof is designed to be as unique in form and colour as the stone surfaces in nature are varied. The MATCH Slate standard modules were supplemented with on-site sheet metal elements.

PROS
  • Adaptable to building and site requirements (colour, texture, shape)
  • The chosen solution could be a solution for listed buildings.
  • The inactive modules provide a neat finish right down to the edges/angles, what not only preserves the appearance of the building, but also optimizes energy production.
CONS
  • Lower energy performance than standard modules.
  • Higher costs than a standard solution.
