Hello sir,
What this parameters cph, ct, ch & cr represent in the solar module which you have uploaded here?

Hello,
I am currently working on a project where I will simulate a solar system that consists of multiple solar panels. I have designed my own panel on Simulink, but it doesn't seem to work quite well. So I was searching the internet for solutions and I bumped into your "Two Diode Solar Cell/Panel Model" files. I was planning to use the mathematical solutions of your model to create my electrical model.
I downloaded your files and as you have described I tried to use the information I have on my solar panels in the "twoDiode.mdl". But as I try to write 48.8 V for the open-circuit voltage Voc in certain blocks (Gain9, Gain10, Agykles1 and Agykles2), this value is not accepted. I tried putting in smaller numbers and it turns out that Gain9 and Gain10 allow me to write 18.23616, while Agykles1 and Agykles2 allow me to put 17.9957 at maximum. Is there anything that I could do to use the value of 48.8 V in your model?

And when I tried to calculate the parameters using the maximum values I mentioned above, I get the error "Algebraic state in algebraic loop containing 'twoDiode/Subsystem/Rp_block/Sum' computed at time 0 is Inf or NaN. There may be a singularity in the solution. If the model is correct, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)."

First of all, thanks for sharing your design. I would also appreciate any help you can give me.

Take care,
Cemre
