Solar Forecast

The following providers are currently available:

• Forecast Solar
• Solarprognose.de - since 0.5.0

Multiple Installations can be entered, like this:

solar_forecast_provider: fcsolarapi
pvinstallations:
  - name: Haus #name
    lat: 48.4334480
    lon: 8.7654968
    declination: 32 #inclination toward horizon 0..90 0=flat 90=vertical (e.g. wallmounted)
    azimuth: -90 # -90:East, 0:South, 90:West -180..180
    kWp: 15.695 # power in kWp
  - name: Garage  #... further installations
    lat: 48.4334480
    lon: 8.7654968
    declination: 32
    azimuth: 87
    kWp: 6.030

The name must be a unique value.

If a solar forecast provider is not available, batcontrol is running on cached values. It stops working if less then 18 hours of forecast are available. That should be enough to overcome outages.
