6. HOW PEAK POWER IS TRACKED?
• By matching of impedance of load and solar module.
• DC-DC converter is used as interface between solar module and load for
impedance matching.
SIMULATION:-

7. METHODS FOR OBTAINING PEAK POWER:-
• PERTURB AND OBSERVE (P & O) ALGORITHM
• INCREMENTAL CONDUCTANCE ALGORITHM
PERTURB AND OBSERVE (P & O) ALGORITHM:-
• P & O method is to modify the operating voltage and current of the PV panel
until you obtain the maximum power.
• The tracker operates by periodically incrementing or decrementing the solar
array voltage.
• We use only voltage sensor to sense the PV array voltage.

10. ADVANTAGES:-
• MPPT method can extract maximum available power from the PV module.
• This method can increase the tracking efficiency.
• Simple to implement.
CONCLUSION:-
• By using MPPT method,efficiency is increased and maximum power is extracted
from the PV module.
• MPPT offers advantages of good tracking efficiency, response is high and well
control for the extracted power.
