The demand for electrical energy is rapidly increasing for the production of fossil fuel-based energy is declining and by this the obvious choice of clean energy source is more in use and helps for the future development of sun’s energy. This paper is summarized for voltage regulation of low power PV modules under partial shaded conditions by the use of Firefly MPPT algorithm. The power voltage characteristic of photovoltaic array is non-linear and it exhibits multiple peaks and one global peak under non-uniform irradiances. In order to track the global peak, MPPT is the important component of PV system. Thereby the theoretical analysis and the experimental results reported in this prove that the optimal inductor current does not depend on the power generated by the PV module provided that the control circuit is powered from the output, but it does on the output voltage level of the storage unit. The proposed experiment shows that the Firefly MPPT algorithm is superior to the other method in tracking speed, convergence to track GMPP and process good tracking efficiency.
