pvlib.modelchain.ModelChain.run_model_from_effective_irradiance#

ModelChain.run_model_from_effective_irradiance(data)[source]#

Run the model starting with effective irradiance in the plane of array.

Effective irradiance is irradiance in the plane-of-array after any adjustments for soiling, reflections and spectrum.

Parameters

data (DataFrame, or list or tuple of DataFrame) –

Required column is 'effective_irradiance'. Optional columns include 'cell_temperature', 'module_temperature' and 'poa_global'.

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.

Notes

Optional data columns 'cell_temperature', 'module_temperature' and 'poa_global' are used for determining cell temperature.

  • If optional column 'cell_temperature' is present, these values are used and temperature_model is ignored.

  • If optional column 'module_temperature' is preset, temperature_model must be 'sapm'.

  • Otherwise, cell temperature is calculated using temperature_model.

The cell temperature models require plane-of-array irradiance as input. If optional column 'poa_global' is present, these data are used. If 'poa_global' is not present, 'effective_irradiance' is used.

Assigns attributes to results: times, weather, total_irrad, effective_irradiance, cell_temperature, dc, ac, losses, diode_params (if dc_model is a single diode model).
