**5. Simulation of the I-V characteristic with MATLAB/Simulink**

To simulate the I-V characteristic of a PV panel, under MATLAB/Simulink using the MOSFET electronic load method shown in **Figure 8**.

block 1 in the previous **Figure 8** is to measure the current intensity in the circuit, block 2 a voltmeter, block 3 the PV panel (SX 330J), and block 4 represents the plotting of I-V and P-V curves, and finally block 5 represents the MOSFET used as a variable load controlled by block 6.
