pvlib.forecast.ForecastModel.cloud_cover_to_irradiance_clearsky_scaling

ForecastModel.cloud_cover_to_irradiance_clearsky_scaling(cloud_cover, method='linear', **kwargs)[source]

Estimates irradiance from cloud cover in the following steps:

  1. Determine clear sky GHI using Ineichen model and climatological turbidity.
  2. Estimate cloudy sky GHI using a function of cloud_cover e.g. cloud_cover_to_ghi_linear()
  3. Estimate cloudy sky DNI using the DISC model.
  4. Calculate DHI from DNI and DHI.
Parameters:

cloud_cover : Series

Cloud cover in %.

method : str

Method for converting cloud cover to GHI. ‘linear’ is currently the only option.

**kwargs

Passed to the method that does the conversion
Returns:

irrads : DataFrame

Estimated GHI, DNI, and DHI.
