ᐅ Ventilation bricks causing issues with photovoltaic systems – any experiences?

Hello everyone,

We are currently building our house with a hipped roof and have now discovered that there might be issues with the photovoltaic system. We will have two vent pipes for the toilets, and the roof will also have two additional vents per side. However, the photovoltaic system takes up a lot of space, and I am looking for a solution and hope for your help.

We will be using vent pipe tiles and ventilation tiles. Under the photovoltaic system, we have 10cm (4 inches) of space, but from what I understand, the tiles are higher than that...

My questions:
1) Can the tiles be shortened? The installer said that if it’s a plastic pipe, it can simply be cut, and the photovoltaic system can be installed over it, so no rain will enter.
2) Could the ventilation (toilet and roof) be rerouted inside the roof so that it exits where we have more space (at the very top)?
3) Are there special flat tiles that we could use?
4) How would you solve this problem?

So long...

even if something enters there. The ventilation is a sealed pipe; if water gets in at the top, it flows out at the bottom, just like the toilet and bath water connected to the ventilation.

Of course, the bathroom ventilation shouldn’t be affected, but the roof ventilation is designed to remove moisture from the roof. That’s what I meant.

Photovoltaic modules do not have any structured water drainage.

What do you mean by that?

Why are such bricks necessary for you? However, the underlayment membrane is also waterproof and can handle small amounts of water ingress.

@Christian K. : What I mean is that you can’t rely on them to keep the water out. Roof tile systems have a sophisticated water drainage design that directs rainwater into the gutter under various wind and weather conditions, keeping the roof dry. Solar panels do not have this.
