Why does the PV voltage vary in steady conditions?

I tried conecting the PV array to a boost converter, but, in steady conditions, the PV array voltage varies, as you can see in the attached image, does anyone know why?

The PV voltage appears to be oscillating around 90 V to 110 V.

Unable to tell without the mathematics at steady-state, but they look like noises.

Hi Fernando,
Thank you for your question.
It seems the model is achived steady state, but the periodic peaks show on top of the voltage signals.
It's possible the way you configure the solver setting has large fixed step size or the model is too stiff to solve the equations.
You probably have to change your solver configurations.
Could you share the Simulink model with us?
Thanks,
Shang-Chuan Lee
