ModelChain.
with_pvwatts
(system, location, orientation_strategy=None, clearsky_model='ineichen', airmass_model='kastenyoung1989', name=None, **kwargs)[source]¶ ModelChain that follows the PVWatts methods.
Parameters: - system (PVSystem) – A
PVSystem
object that represents the connected set of modules, inverters, etc. - location (Location) – A
Location
object that represents the physical location at which to evaluate the model. - orientation_strategy (None or str, default None) – The strategy for aligning the modules. If not None, sets the
surface_azimuth
andsurface_tilt
properties of thesystem
. Allowed strategies include ‘flat’, ‘south_at_latitude_tilt’. Ignored for SingleAxisTracker systems. - clearsky_model (str, default 'ineichen') – Passed to location.get_clearsky.
- airmass_model (str, default 'kastenyoung1989') – Passed to location.get_airmass.
- name (None or str, default None) – Name of ModelChain instance.
- **kwargs – Parameters supplied here are passed to the ModelChain constructor and take precedence over the default configuration.
