Hello everyone,

we are currently planning roof windows. Below you will find the attic floor plan, where the windows have been placed provisionally:


Upper floor plan with roof terrace, staircase, and living area

As you can see, there are also windows on the gable side. The roof space will be used as a studio and has no other interior walls.

Are 6 roof windows too many? Maybe you have some experience with this.

If you know the actual photovoltaic modules and the roof structure, this might also be possible. Then it would be a maximum of 52 modules, resulting in 22.88 kWp.

@hanghaus2023: Many thanks for the arrangement. We hadn’t thought of placing three roof windows side by side in the middle. What module dimensions did you assume? Standard sizes are around 180 x 115 cm (71 x 45 inches).

We still have a chimney coming out in the middle, but we plan to move it towards the bottom of the roof to better fill the roof area with photovoltaic modules.

I planned with LxWxH: 1762x1134x30 mm (69.4x44.6x1.2 inches). However, you need to consider gaps of 2 cm (0.8 inches). The standard is quite close to this.

Skipping one cell due to the chimney should not be a problem. The shadow cast by the chimney should be taken into account.

That’s a case of the tail wagging the dog.

Actually not, since the fireplace position in the corner of the living room is more suitable anyway.

The main thing is to be close to the chimney, due to the current regulations.
