(weather)[source]¶ Prepare the solar position, irradiance, and weather inputs to the model, starting with GHI, DNI and DHI.
- Parameters
weather (DataFrame, or tuple or list of DataFrame) –
Required column names include
'dni'
,'ghi'
,'dhi'
. Optional column names are'wind_speed'
,'temp_air'
; if not provided, air temperature of 20 C and wind speed of 0 m/s will be added to the DataFrame.If weather is a tuple or list, it must be of the same length and order as the Arrays of the ModelChain’s PVSystem.
- Raises

ValueError – If weather is a tuple or list with a different length than the number of Arrays in the system.
