Why is the solar cell simulation not working?

Hello,

I have been trying to use the simscape solar cell block to reproduce data that I have actually gathered.

This is the simulink model that I am using:

I have set the short circuit current to 48mA, and the open circuit voltage to 5.4 V. This is data from an actual solar panel, for which I created the IV curve.

It does not produce any sort of curve, merely a straight line. And it appears to have malfunctioned.

I believe that my short circuit current data is too low for the simulation, but this is data that I actually gathered.

If anyone has any information about the suject I would be very grateful.

Same problem for me. Matlab & Simulink version 2019b.

An example that shows how to generate the power-voltage curve for a solar array with Simscape Electrical:

Since R2024b, you can also generate a digital datasheet for the Solar Cell block, including current-voltage (I-V) and power-voltage (P-V) curves, using a MATLAB® live script. The script imports the parameters from the Solar Cell block you select in the model. You can use these characteristic curves to evaluate the maximum power point tracking (MPPT) output, because the curves help to identify the peak power at various irradiance levels and cell temperatures. To open the MATLAB live script:

1. Double-click the block to open the Block Parameters window.
2. Open the Description tab.
3. Click the Generate datasheet hyperlink.

To generate the datasheet, in the live script, click the Generate Datasheet button.
