The Problem: Your Cable Chafes Through the Tile
You want to route your solar cable from the roof into the house. The critical point is where the cable runs between the tiles – it rests on the sharp edge of the tile there. With every gust of wind and every temperature change, it rubs minimally, and over the years, the insulation chafes through. That's exactly what you want to prevent.
The Solution: A Gland as Abrasion Protection
Our PV roof gland made of TPU sits between the cable and the tile. The cable no longer rests on the sharp edge but is protected in the soft, flexible material – the insulation remains intact for good.
Important to know: The gland is abrasion protection, not a sealing replacement. Your roof will be sealed as usual by the tile covering.
Here's How – Step by Step
- Lift the tile and choose the position for the gland (as close as possible to the cable run).
- Slightly grind down the tile at the bearing edge so that the gland sits cleanly.
- Insert the cable and hook in the gland.
- Replace the tile – done, the cable is protected.
By the way: You don't have to cut the MC4 connector for this – the cable is inserted with the connector.
What Size Do You Need?
- 105 mm – Standard for most tiled roofs
- 125 mm – e.g. for Frankfurter/Finkenberger Pfanne
- 150 mm – Universal, with extra space
All made of TPU, Made in Germany, UV-resistant and durable.
FAQ
Does the gland seal my roof? No – it protects the cable from abrasion. The tile covering ensures the watertightness.
Do I have to cut the MC4 connector? No, the cable is inserted with the connector.
Is this suitable for my balcony power plant? Yes, ideal for balcony power plants and for larger PV systems.
Conclusion
Protecting the cable at the tile edge is the difference between "runs for years" and cable damage on the roof. Check out the suitable PV roof glands.
