The issue arises because the PV array's output voltage is extremely high, resulting in a (Vd/Vt) ratio of around 3. 8e4.The issue can be resolved by decreasing the value of the shunt resistance (Rsh) connected with the diode to reduce the Voltage drop across the PV array as Vd depends on PV array voltage as (Vd=V_PV + Rs*I_PV)
The Number of series cells (Nser) can be increased to increase the threshold voltage of the diode to achieve the desired Vd/Vt levels or to use a DC-DC converter to regulate the output voltage of the PV array
Kindly refer to the below documentation of “pv array” for more details:
I hope this helps!
