Some inputs do not have default values and may be assigned a value from the variable’s Required attribute. See variable attribute descriptions below.

PySAM.TcslinearFresnel.from_existing(data, optional config) → TcslinearFresnel

Share data with an existing PySAM class. If optional config is a valid configuration name, load the module’s defaults for that configuration.

Interdependent Variables

The variables listed below are interdependent with other variables. If you change the value of one of these variables, you may need to change values of other variables. The SAM user interface manages these interdependent variables, but in PySAM, it is up to you change the value of all interdependent variables so they are consistent. See Interdependent Variables for examples and details.
