The performance of a photovoltaic (PV) cell is highly dependent on the operating environment due to changes in radiation and temperature, which makes its maximum power point (MPP) also vary. MPPT techniques to improve power efficiency are becoming more efficient and accurate, but they are also more complex, expensive, and difficult to use. Meanwhile, the traditional solution and its improvements showed quite simple, practical, and effective. This paper introduces an improved MPPT solution based on the perturbation and observation (P&O) method by estimating the initial points in order to reduce the iteration step and increase the convergence speed. The simulation results in PSIM environment pointed that the power loss is significantly reduced due to the increased convergence speed, thereby improving the performance in the condition of changing the uniform operating environment on the system.
