An equivalent electric circuit is exploited for interpreting the dynamic behavior of a photovoltaic (PV) panel based on the commonly used one-diode model with an additional parasitic capacitance. By drawing rippled currents from the PV panel with a boost converter, the circuit parameters of the model can be obtained simply from a few test points without the need of the intrinsic parameters of the PV panel given by datasheets. Experimental tests are carried out on a laboratory system to demonstrate the capability of simulating the dynamic responses of a PV panel with the derived circuit parameters.
