Hi,

for estimating the potential energy yield with non-standard modules, you could try the Solarrechner from EnergieSchweiz or PVGIS. In the Solarrechner, under “weitere Einstellungen,” you can enter the module efficiency manually, so it works for non-standard modules. In PVGIS, you enter the installed peak PV power (kWp), which already takes efficiency into account.

Shading is a bit trickier. If the façade is strongly shaded, it’s worth considering whether PV modules make sense there. For more detailed analysis, you could use tools like Hive or Ladybug, or Sunpath 3D for shading studies (https://platform.idaida.ch/course/view.php?id=89). Sunpath 3D shows solar paths and shadow projections in 3D, letting you see how trees, neighboring buildings, or other obstructions affect sunlight exposure.
