I have a question about the PV array. I create a boost DC/DC converter where I have a PV array as input and the inputs of the PV array are a random function that represents irradiance and temperature. So, there would be a changeable input voltage. My professor wants that change to be around 2-3V(in my case 10-13V) but there is a small change of about 0.5V. The question is how to make that change and is it possible? Because I have only 2 parameters that I can change in the PV array(serial and parallel numbers of panel).

Hi Marko,
The output voltage of the “PV Array” block is measured across the shunt resistance “R_sh_5%” connected in parallel with the diode. The higher values of the output voltage can be reduced by increasing the drop across the shunt resistance. To achieve the desired output, the parameter “R_sh_5%” can be tuned by looking under the “PV array” mask using the “Ctrl+U” keyboard shortcut while the block is selected.
Kindly refer to the below documentation of “PV Array” for more details:

I hope this helps!
