This paper presents a maximum power point tracking (MPPT) of single-phase grid connected photovoltaic (PV) system using non-iterative method. The proposed method considers the change in PV voltage. The reference maximum power of PV panel was calculated by the open-circuit voltage (Voc). Therefore, the power response using the proposed method is faster than that from the iterative MPPT methods. The effectiveness of the proposed non-iterative method was confirmed by computer simulation and hardware in the loop simulation using a TMS320F28335 microcontroller board with MATLAB/Simulink. The results show that the proposed MPPT method can reach the maximum power point in a shorter time compared with the traditional iterative methods.
