Pv6parmod¶
Wrapper for SAM Simulation Core model: cmod_pv6parmod.cpp
Creating an Instance¶
There are three methods to create a new instance of a PySAM module. Using default
populates the newclass’ attributes with default values specific to a config
. Each technology-financialconfiguration corresponds to a SAM GUI configuration. Using new
creates an instance with empty attributes. The wrap
function allows compatibility with PySSC, for details, refer to PySSC.
Pv6parmod model description
Pv6parmod

PySAM.Pv6parmod.
default
(config) → Pv6parmod¶ Use financial config-specific default attributes
-
PySAM.Pv6parmod.
from_existing
(data, optional config) → Pv6parmod¶ Share underlying data with an existing PySAM class. If config provided, default attributes are loaded otherwise.
-
PySAM.Pv6parmod.
new
() → Pv6parmod¶
-
PySAM.Pv6parmod.
wrap
(ssc_data_t) → Pv6parmod¶ Use existing PySSC data
Warning
Do not call PySSC.data_free on the ssc_data_t provided to
wrap
Functions¶

Pv6parmod
¶ This class contains all the variable information for running a simulation. Variables are grouped together in the subclasses as properties. If property assignments are the wrong type, an error is thrown.
-
assign

nested_dict = { 'Weather': { var: val, ...}, ...}
-
execute

-
export
() → dict¶ Export attributes into nested dictionary
-
value
(name, optional value) → Union[None, float, dict, sequence, str]¶ Get or set by name a value in any of the variable groups.
