Azimut setting in pv forecast

[bennobiber]

First of all, thank you for your amazing work to make this project available 🙏

My question is regarding the azimut angle. Does azimut=0 correspond to south? In the EOS doc by akkudoktor 180deg means south and 0 north respectively. But when i set up my pv configuration and chose 160 deg for south but slightly facing east the predicted yield is roughly 50% of what i really get.
Then i changed azimut to -20 and it looks better. Maybe you could clarify this in the doc which angle corresponds to which direction. Many thanks 🙏

Good point, thanks.

I've added

Important:
All supported PV forecast providers (akkudoktor, openmeteo, openmeteo_local, forecast_solar, evcc) use the same azimuth convention where 0° = South and negative values = East.
No conversion is needed when switching between providers.

and

• azimuth:
  Azimuth angle for the PV forecast in degrees. All supported forecast providers use the same solar/PV industry standard convention:

  • 0° = South (optimal orientation for Northern Hemisphere)
  • 90° = West
  • 180° = North
  • -90° = East (negative values for east-facing)

  Example orientations: A south-facing roof would use azimuth: 0, while a garage facing southeast would use azimuth: -45, and a carport facing west would use azimuth: 90. An east-facing installation would use azimuth: -90.
