I would not orient my house according to a photovoltaic system.
That is far too fast-paced and possibly outdated again in 5 or 10 years. If you can build one on it, you should do it; if not, you should leave it. However, turning the house on the plot just to get the modules in the right direction is not something I consider desirable.
Today, you still need 25 modules for 10 kWp. Ten years ago, it was 50 modules, and in 10 years, you will only need 5 modules.
Seen as an example.
And with the plot, it would make sense to mount the modules on a frame at the back edge of the property. There they get sun all day long.
