LocalizedPVSystem
(pvsystem=None, location=None, **kwargs)[source]¶ 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.
See the
PVSystem
class for an object model that describes an unlocalized PV system.Methods
