The photovoltaic system being always built of a PV source (panel) and a converter (or inverter) has its own specific properties that are frequently overlooked leading to unrealistic de
signs
We showed here that at the PV-converter interface the signal is far from DC asking for knowledge of the dynamic properties of the PV side. There from come the interest for the frequency response of the PV cell. To get it an ANN based model was developed here that enables simple and inexpensive extraction of the frequency response.
