pvlib.modelchain.ModelChain.run_model_from_poa#
- ModelChain.run_model_from_poa(data)[source]#
Run the model starting with broadband irradiance in the plane of array.
Data must include direct, diffuse and total irradiance (W/m2) in the plane of array. Reflections and spectral adjustments are made to calculate effective irradiance (W/m2).
- Parameters:
data (DataFrame, or tuple or list of DataFrame) –
Required column names include
'poa_global','poa_direct'and'poa_diffuse'. If optional columns'temp_air'and'wind_speed'are not provided, air temperature of 20 C and wind speed of 0 m/s are assumed. If optional column'cell_temperature'is provided, these values are used instead of temperature_model. If optional column'module_temperature'is provided, temperature_model must be'sapm'.If the ModelChain’s PVSystem has multiple arrays, data must be a list or tuple with the same length and order as the PVsystem’s Arrays. Each element of data provides the irradiance and weather for the corresponding array.
- Returns:
self
- Raises:
ValueError – If the number of DataFrames in data is different than the number of Arrays in the PVSystem.
ValueError – If the DataFrames in data have different indexes.
