sunpeek.core_methods.virtuals.radiation.get_horizontal_irradiance_from_ghi

sunpeek.core_methods.virtuals.radiation.get_horizontal_irradiance_from_ghi(plant, ghi, model='erbs-driesse')

Decompose measured global horizontal irradiance into DNI and DHI.

Parameters:

• plant – Plant-like object with calculated solar position sensors.

• ghi (pd.Series) – Measured global horizontal irradiance in W/m².

• model (str) – Decomposition model. Currently 'erbs-driesse' and 'erbs' are supported.

Returns:

Columns ghi, dni and dhi in W/m².

Return type:

pd.DataFrame
