Solar module is widely used in this modern world nowadays. It is not only can be found in industrial companies but also houses because many houses use solar as a generator for electrical appliances. This project included designing, analysing and observing the PV model and half-bridge inverter using SPWM method. The Fast Fourier Transform (FFT) also included. The method includes connecting the solar module with other connection such as op-amp and gating blocks as to observe the performance of the PV and inverter respectively. The FFT is being applied to the output waveform of the result and next the value of Total Harmonic Distortion (THD) of the signal is being analysed. To calculate the THD, the amplitudes of the harmonics are required and FFT can be an assist of to determine the THD value. As the output waveform is in square waveform it is possible to perform FFT.
