ᐅ Experiences with Photovoltaic Systems from Roto / Sunroof Pur?

Hello,
Could someone please answer a few questions I have about a photovoltaic system?
My wife’s cousin works as a sales representative for the company Roto. He could get us in-roof systems at a good price.
Does anyone have experience with their product “SunRoof Pur”?
What are the advantages and disadvantages compared to an on-roof system? What are the benefits of an in-roof system?
I have heard that an in-roof system heats up the attic more than an on-roof system because the air layer between the tiles and the photovoltaic system is missing. Is this true?

Thank you very much for your answers.

Did your cousin install the system or not?
