Hello there,

I am trying to simulate the performance of a PV system and I have the site irradiance and assume a constant temperature. However, the voltage readings are not looks right. The voltage rise rate doesn't look right and I even have a voltage at zero irradiance and I have zero current reading as shown in the attachments. When I connected a current source to drain current, results become more unlogic to me.

Can you share the model for more detailed investigation?

Hi @Ameen Bassam,

The observed initial voltage curve follows the characteristic curve shown below using the "module data parameters" from the shared ".slx" file. This curve is then affected by irradiance.
