​Querying Observations

​Irradiance and Expected PV Production

The /observation/realtime end point provides near real-time irradiance measurements. The following request returns

  • various irradiance parameters and the "expected" PV production,
  • for a south-facing (180°) solar panel with a tilt of 25°,
  • for the past 24 hours,
  • taking into account shading caused by the surrounding terrain/horizon.
