In electrical engineering, Maximum Power Point Tracking (MPPT) is a technique used to maximize the power extraction from a photovoltaic (PV) system. It is a common method used in PV systems to get the maximum possible power from the PV cells.The MPPT algorithm is used to find the operating point of the PV system that will give the maximum power output. The algorithm varies the operating point of the system according to the changing conditions, such as solar insolation and temperature.
