OBJECTIVE
• What is a solar cell?
A solar cell converts optical energy directly into electrical energy.
• Efficiency of solar cell is less, it only converts 30-40% of energy incident on
it to electrical energy.
• Efficiency of solar cell is increased by a technique called maximum power
point tracking. By installing this technique we can get additional 20-30% of
extra energy.

PV ARRAY COMPONENTS

Mathematical Model of a Solar Cell

INTRODUCTION
 What is MPPT?
It is an electronic system that operates the photovoltaic
modules in a manner to extract the maximum power from the
system.
 What is maximum power point?
It is the operating point at which maximum power can be
extracted from the system. Usually represented as MPP.
 Generally MPPT is installed in between PV system and load.
Coupling to the load for maximum power transfer may require
either providing a higher voltage at lower current or lower voltage
at higher current.

PERTURB AND OBSERVE
(HILL CLIMBING)
 P&O method modifies the
operating voltage or current of
the PV panel until you obtain
maximum power from it.
In this we use only voltage
sensor to sense the PV array
voltage.

Solar PV Model With MPPT (P & O method)

APPLICATIONS
 Space and orbital station.
• Cost and complexity are not an issue.
• High reliability and performance.
 Residential use.
• Partial shading issue, payback time.
• Two stage incremental conductance.
 Street lighting.
• Charging of batteries during the day.
• Easy and cheap implementation is more important.
 Photodiodes.

ADVANTAGES
 MPPT method can extract maximum available power from the
PV module.
 This can increase the tracking efficiency.
 If our energy use is greatest in the winter(typical in most
homes)and we have cold winter weather, then we can gain
substantial boost in energy when we need it the most.
 It will decrease the burden on fossil fuels which are rapidly
exhausting.

CONCLUSION
 P&O algorithm holds good performance than any other method
under normal and varying atmospheric conditions.
 Power output obtained from P&O method is high as compared to
other methods and also it is simple and has easy
implementation.
 A most suitable MPPT technique is chosen based on the
implementation cost , number of sensors required, complexity.
So overall for residential and industrial purposes P and O
performs better results especially in medium level.

FUTURE SCOPE
 An extension of this project would be to directly power the
microcontroller and other circuits from the solar panel instead
of from a power supply.
 Improvements to this project can be made by tracking the
maximum power point in changing environmental conditions.
 This can be done by using SIMULINK model to carry out
MPPT instead of writing its code in embedded MATLAB
functions.
