pvlib.pvsystem.LocalizedPVSystem

class pvlib.pvsystem.LocalizedPVSystem(pvsystem=None, location=None, **kwargs)

The LocalizedPVSystem class defines a standard set of installed PV system attributes and modeling functions. This class combines the attributes and methods of the PVSystem and Location classes.

The LocalizedPVSystem may have bugs due to the difficulty of robustly implementing multiple inheritance. See ModelChain for an alternative paradigm for modeling PV systems at specific locations.

__init__(pvsystem=None, location=None, **kwargs)

Initialize self. See help(type(self)) for accurate signature.
