Pv6parmod¶
Wrapper for SAM Simulation Core model: cmod_pv6parmod.cpp
Input Consistency Warning¶
As described in Possible Problems, some input parameters are interdepedent but the equations accounting for these interdependencies that enforce consistency among these input parameters are not available in the PySAM module. Therefore, the onus is on the PySAM user to check that interdependencies are correctly handled. The variables which may require additional logic include:
Provided for each of these inputs is a list of other inputs that are potentially interdependent.
Creating an Instance¶
Refer to the Initializing a Model page for details on the different ways to create an instance of a PySAM class.

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.
