Abstract The series connection of Photovoltaic Module (PV) in the string result in the lowest string current under partially shaded condition of PV module. It reduces the overall output power of solar panel. In this paper, a new efficient Distributed Maximum Power Point Tracking (DMPPT) method is used to improve the output power of partially shaded PV source. Current compensation of each PV module occurs by regulating the voltage by connecting an interleaved flyback (dc-dc) converter across each PV module for maximizing the output power. The operation of DMPPT is implemented in hardware.
