Many say that the IN-roof system is not as well ventilated.
How much this actually affects performance – no idea!
In our case, choosing the IN-roof solution for the new build definitely wouldn’t have been worth it.
It would have been about €5000 more expensive than the tile + ON-roof system.

You get less performance for more money. That’s an option if you have extra money to spend. But money is usually one of the things you don’t have left over when planning a house. That said, I don’t want to preach or convince you—you can (and will) do whatever you prefer.
In my opinion, whether it’s my system, my neighbors’ or in the surrounding area… no one really looks at or pays attention to whether it’s an on-roof or in-roof system.
By the way, here is a photo of a somewhat older in-roof system, discovered two weeks ago. Appearance… hmm…

In-roof installation is often said to have poor ventilation, according to many..
How much this negatively affects performance – no idea?! There won’t be much ventilation with in-roof systems. This affects the efficiency of the system. Typically, solar panels lose about 4% efficiency for every 10°C (18°F) increase in temperature. Ventilation helps keep the temperature lower and thus generates more power.
Are you familiar with PVGIS? This tool for yield estimation can help you assess the difference for your situation. However, in-roof installations are often so much more expensive that they are not financially worthwhile.
