ModelChain#

Creating a ModelChain object.

`modelchain.ModelChain`(system, location[, ...])	The ModelChain class to provides a standardized, high-level interface for all of the modeling steps necessary for calculating PV power from a time series of weather inputs.
`modelchain.ModelChain.with_pvwatts`(system, ...)	ModelChain that follows the PVWatts methods.
`modelchain.ModelChain.with_sapm`(system, location)	ModelChain that follows the Sandia Array Performance Model (SAPM) methods.

Running#

A ModelChain can be run from a number of starting points, depending on the input data available.

`modelchain.ModelChain.run_model`(weather)	Run the model chain starting with broadband global, diffuse and/or direct irradiance.
`modelchain.ModelChain.run_model_from_poa`(data)	Run the model starting with broadband irradiance in the plane of array.
`modelchain.ModelChain.run_model_from_effective_irradiance`(data)	Run the model starting with effective irradiance in the plane of array.

Functions to assist with setting up ModelChains to run

`modelchain.ModelChain.complete_irradiance`(weather)	Determine the missing irradiation columns.
`modelchain.ModelChain.prepare_inputs`(weather)	Prepare the solar position, irradiance, and weather inputs to the model, starting with GHI, DNI and DHI.
`modelchain.ModelChain.prepare_inputs_from_poa`(data)	Prepare the solar position, irradiance and weather inputs to the model, starting with plane-of-array irradiance.

Results#

Output from the running the ModelChain is stored in the modelchain.ModelChain.results attribute. For more information see modelchain.ModelChainResult.

Attributes#
