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.
