This document discusses methods for obtaining peak power from photovoltaic (PV) systems, including manual tracking and maximum power point tracking (MPPT) algorithms. It describes how PV cells work to convert sunlight into electricity. MPPT algorithms like perturb and observe (P&O) and incremental conductance (INC) are used to automatically track the peak power point by matching the impedance of the solar module to the load. These algorithms help ensure PV systems operate efficiently without needing manual adjustment.
