cloud_cover_to_irradiance_ghi_clear
(cloud_cover, ghi_clear, zenith)[source]¶ Estimates irradiance from cloud cover in the following steps:
- 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.
Parameters: - site (datamodel.Site) –
- cloud_cover (Series) – Cloud cover in %.
- zenith (Series) – Solar zenith
Returns: ghi (pd.Series, dni : pd.Series, dhi : pd.Series)
