pvlib.modelchain.ModelChain.run_model

ModelChain.run_model(weather, times=None)

Run the model.

Parameters:

• weather (DataFrame) – Column names must be 'dni', 'ghi', 'dhi', 'wind_speed', 'temp_air'. All irradiance components are required. Air temperature of 20 C and wind speed of 0 m/s will be added to the DataFrame if not provided.
• times (None, deprecated) – Deprecated argument included for API compatibility, but not used internally. The index of the weather DataFrame is used for times.

Returns:

• self
• Assigns attributes (solar_position, airmass, irradiance,)
• total_irrad, effective_irradiance, weather,
• cell_temperature, aoi, aoi_modifier, spectral_modifier,
• dc, ac, losses,
• diode_params (if dc_model is a single diode model)
