Hello everyone,
We have received different offers for solar systems, one as an integrated roof solution and one as an on-roof system.
Apart from the price for the modules and installation (and the appearance), I am interested in which option is better.
I am mainly concerned about issues such as the roof’s vulnerability to water ingress, additional costs for metalwork (possibly required for the integrated roof?), and so on.
I would appreciate any information on what to watch out for with both options! 🙂

With in-roof systems, problems can arise if a module breaks and there is no replacement available in the same size.
In-roof systems have a slightly lower efficiency because they are either not ventilated or poorly ventilated.
It is difficult to determine the tightness in general. With a rooftop installation, roof tiles are often cut to mount the brackets for the mounting frame, even though there are special roof tiles designed for this purpose. With the in-roof system, you save the roof tiles on the covered area. However, the flashing work will be more extensive.
I was also faced with this choice and ultimately decided on a rooftop installation. But that was mainly due to the different concepts and the price. The in-roof system was correspondingly more expensive. Although I did not compare what the lower price for roofing would have been.

Hello
Whether to mount on the roof surface or under the roof membrane is certainly a matter of preference. From a technical point of view, mounting under the roof membrane has disadvantages. Although these issues rarely occur and mostly affect older systems, they should also be considered for new installations.
Systems and installation costs
Potential weak points in the roofing
Thermally highly stressed collector connections that are not easily accessible.
