fixed Voltage mppt

Hi everyone I am new here so not sure how these threads work (format wise). I am doing an assignment that I need to simulate PV panels and track it maximum power.

I am wondering if anyone knows what this initial dip is called in my power graph and how to correct it?

I need more information.
What panel? Data sheet?
What simulator? Spice? LTspice?
How did you get the graph?

Welcome!

because of shading, initial dip you mentioned is occured. or it will be because of that solar arrays are connected in series, paralel. and all pv can not generate the same voltage. So the initial dip is occured
