INTRODUCTIONNeed For Renewable EnergyRenewable energy is the energy which comes
from natural resources such as sunlight, wind, rain , tides and geothermal heat.
Renewable resources can be naturally replenished
These resources can be considered to be inexhaustible

What is MPPT? It is an electronic system that operates
the Photovoltaic (PV) modules in a manner
that allows the modules to produce all the
power they are capable of. MPPT is not a
mechanical tracking system that
“physically moves”.
How does an MPPT work?
FEATURES OF MPPT?It forces MPPT to draw maximum available
powerIt allows user to draw a higher voltage
compared to other charge controllersE.g.: Small Water Turbines

Comparison With Other Charge ControllersFeatures of MPPT is rich compared to other
controllers
Efficiency is 15 % and 30% more than other charge controllers during sunny and low light conditions
LIMITATIONSIncrease in initial cost
CONCLUSIONIt is a single chip solution for battery
charging method and driving LED’S.Charging efficiency and thereby life span of
the battery is improved
