 How Does PV works?                                                                 Methods for obtaining Peak Power
 • The photovoltaic cell is basic        Combining Solar Cells
   component of PV system.                                                                  •   Manual tracking is waste of time
 • Converts solar enrgy to               •   Much higher voltage is required for            •   MPPT Algorithms are used for
   electric energy.directly                  practical application                              automatic peak power tracking

                                                                                                MPPT Algorithms


• In essence, sunlight on a solar
   cell creates a small battery
   with voltages typically 0.5 v.
                                         How Peak Power Is Tracked?
                                    •    By matching impedance of load
Iph                                      and solar module                              P&O ALGORITHM
                                    •    Dc-Dc converter is used as              Conclusion:                   INC ALGORITHM
                                         interface between solar module
                                                                                   •    PV system getting more significance due to
                                         and load for impedance
                                                                                        shortage and environmental impact of
                                         matching
                                                                                         conventional fuels.
                                                                                   •    P&O algorithm is simple to implement since
                                                                                   •    no previous knowledge of PV module
                                                                                        required.
                                                                                   •    INC works good under rapidly changing
                                                                                         environment condition and also achieves
                                        Controlled MPPT PV system                        a decrease in oscillation at MPP.
