ᐅ Preparation for Photovoltaic System – Installation of Tile with Conduit for Cable Routing

Hello everyone,

Our roof will be covered in the next few days. For budget reasons, we plan to install a photovoltaic system in about 5 years. However, we are already making preparations now to minimize the work needed later (e.g., in the roof insulation layer).

A roof tile with a passage for the photovoltaic system and conduit to the building services room will be installed. In the attic, the cables from the roof can be pushed through the conduit to the building services room.

Roof orientation: South/North
Horizontal base area of one roof side: 9 m x 4.5 m (30 ft x 15 ft)
Roof overhang: 40 cm (16 inches)
Roof pitch: 42°
Roof windows: 4

The passage roof tile will be placed on the south-facing roof just below the ridge. Cables can be routed under the roof tiles to the north roof, in case it is used for a photovoltaic system later, which I currently do not expect. A conduit with an inner diameter of 40 mm (1.5 inches) was planned.

See the sketches in the pictures.

I would appreciate any advice on the planned approach.

Best regards,
enno

Photovoltaic systems are best installed during initial construction. Retrofitting is always more expensive (scaffolding, etc.).
Financing is available very affordably through KfW.
