cloud_cover_to_irradiance
(latitude, longitude, elevation, cloud_cover, apparent_zenith, zenith)[source]¶ Estimates irradiance from cloud cover in the following steps:
- Determine clear sky GHI using Ineichen model and climatological turbidity.
- Estimate cloudy sky GHI using a function of cloud_cover and
ghi_clear:
cloud_cover_to_ghi_linear()
- Estimate cloudy sky DNI and DHI using the Erbs model.
Don’t use this function if you already have clear sky GHI. Instead, use
cloud_cover_to_irradiance_ghi_clear()
Parameters: Returns: - ghi (pd.Series)
- dni (pd.Series)
- dhi (pd.Series)
