Solar system on the roof or integrated into the roof, which is better?

Hello andre02,

for a new build, an integrated system is optimal, as material (tiles, etc.) is saved at the spot where the collectors are mounted. Visually, such a solar system of course offers a great advantage compared to surface-mounted installation, as the seamless transition into the roof or roof covering provides a harmonious image without "disturbing factors." The flashing around the collectors guarantees tightness and weather protection at the points where the roof covering is then missing.

In terms of price, an integrated system is naturally more expensive, as in addition to the collectors, the flashing (eaves flashing, ridge flashing, ventilation caps, intermediate flashing, and side flashing) is added. However, as already mentioned, material for roofing is saved in a new build.

I took the information from a blog by "Fession." I think if it comes to cost comparison or technical data in detail, you can also contact such a specialist on the internet for further information.

In my opinion, due to the advantages listed above, I would opt for an integrated system in a new build.

Best regards, Noiss

For reasons of summer thermal protection, I would always prefer a roofing system! Simply carry out a cooling load calculation. In addition, the efficiency of photovoltaics should be better.

Hi
It should also be noted the aspect of the roof pitch. With [Indachmontage] you inherit the roof pitch 1:1, with [Aufdachmontage] you can to a certain extent deviate from it to get closer to the optimum for the location.
