PV Roof Penetration for Concrete Roof Tiles — Made in Germany
Concrete roof tiles (concrete roof pans) from manufacturers such as Braas, Nelskamp, or Benders are among the most common coverings on modern and renovated roofs. Their profiled shape – such as the Frankfurter Pfanne – makes PV installation straightforward. However, at the cable exit point, the cable can easily rub against the edge of the tile. The Dachdurchführung24 cable penetration made of UV-resistant TPU acts as mechanical abrasion protection around the cable and protects it permanently.
Why Dachdurchführung24 fits concrete roof tiles
- Abrasion protection at the tile edge — flexible TPU prevents PV cables from rubbing through
- Matches the profile shape — 125 mm is the standard size for Frankfurter and profiled pans; 105 mm for flatter, 150 mm for higher or large-wave profiles
- Tool-free installation — insert cables including MC4 connectors through the side slots
- TPU, Made in Germany — UV-resistant, -40 °C to +80 °C, available from stock
Product Variants
Available for 2 and 4 PV strings, each with or without an earthing passage (PE). Lengths: 105 / 125 / 150 mm — for the typical concrete roof pan (Frankfurter Pfanne), 125 mm is the standard choice.

Frequently Asked Questions
Which size fits concrete roof tiles or the Frankfurter Pfanne?
For the common profiled/Frankfurter pan, 125 mm is the standard size. 105 mm fits flatter profiles, 150 mm for higher or large-wave tiles. If in doubt, briefly measure the tile width at the planned penetration point.
Is the penetration suitable for Braas, Nelskamp, or Benders tiles?
Yes. Profiled concrete roof tiles correspond in shape to profiled clay roof tiles; the penetration can be adapted to the respective model via the three lengths.
Do the MC4 connectors need to be dismantled?
No. The cables, including the connectors, are inserted through the side guide slots – this saves time on the roof.
Does the installation damage the concrete roof tile?
No. The penetration is inserted into the existing cable opening and protects the cable from abrasion at the tile edge – the roofing remains unaffected.
