Photovoltaic systems on pantile roofs: K2 Systems hanger bolts

In Southern European markets, roofs covered with pantiles or similar clay roof tiles are particularly common. In many cases, these tiles are bonded or rigidly fixed to the roof substructure, meaning they cannot be lifted.

This makes the use of conventional roof hooks impractical for securing the mounting structure, limiting traditional solutions for installing photovoltaic modules. This is where K2 Systems hanger bolts provide an effective alternative.

K2 Systems’ technical solution

To meet this specific requirement for installers, K2 Systems has developed an effective and proven technical solution: hanger bolts, also known as double-threaded screws.

How do hanger bolts work?

• They pass through the roof tile without requiring its removal
• They are anchored directly into the roof substructure
• They provide stable and secure fastening, even on complex roof coverings

This configuration is fully compatible with K2 Hanger Bolts combined with K2 SingleRail and K2 SolidRail mounting systems, ensuring maximum flexibility at the system design stage.

Hanger bolts: when roof hooks cannot be used

The K2 Systems solution provides a professional, safe and reliable option for photovoltaic installations on pantile roofs.

It overcomes the limitations of conventional mounting systems, simplifies installation work and ensures a stable and durable PV installation.
