Prepare the solar position, irradiance, and weather inputs to the model.

Parameters

  • times (None or DatetimeIndex, default None) – Times at which to evaluate the model. Can be None if attribute times is already set.

  • weather (None or DataFrame, default None) – If None, the weather attribute is used. Column names must be 'dni', 'ghi', 'dhi', 'wind_speed', 'temp_air'. All irradiance components are required. Assumes air temperature is 20 C and wind speed is 0 m/s if not provided.
