The photovoltaic source has two external Inputs:
G: Instantaneous value of solar radiation on the panel (W/m2).
T: Instantaneous value of cell operating temperature (°C).
When you send a constant value to these inputs, your monitoring components show constant values and no error has occurred! In your image (fig.1), you send 1.2k to G (solar_irradiane) and monitor window shows it correctly. In second image (fig.2) a function is defined to change the input. This function can be implemented with components of CSM Functions (master lib: CSMF) very easily.
If you have further questions, please let me and other contributors know.
