Hi Matteo,
Sorry for the late response.
Without the definition and all the required files attached, it is very difficult to identify the issue from the screenshots.
Even if those were attached, I would have to have all the same installed plugins, and spend some investigating.
Here is the help that I can provide:
If width of the window is larger, try splitting the PVsurfaces into smaller pieces, where each piece corresponds to some approximate PV module size.
Also read this topic for more explanation on how ‘Sun Path’ component works. Maybe this is causing the issue with results.
On PVsurface angles:
Depending on what is the priority in your project (energy consumption in the room behind the window or PV energy generation). If it is the second one, then to generate the louvers, you should use the ‘PV SWH system size’ component. Try searching for this component’s name here, and on the old forum as well, just to see how it can be used. You won’t be able to download majority of attached .3dm/.gh files from older topics on this discourse forum, thus you would have to search for them on the old one.
Essentially the ‘baseSurface_’ input of your ‘PV SWH system size’ component would represent the window opening.
