PV module array

Hello,

What MATLAB (Simulink) block are you referring to, this one (https://www.mathworks.com/help/physmod/sps/powersys/ref/pvarray.html)? In PLECS, various demo models contain unofficial PV module subsystems that are inspectable and allow for custom modifications. You may not find the exact design as you find in other software, but are therefore able to implement your own model. From a quick web search, here are some resources you might find helpful:
