3. Objective :
What is solar cell ?
A Solar cell converts optical energy directly into electrical energy.
It is essential a semiconductor device fabricated in a manner which
generates a voltage when solar radiation falls on it.
Efficiency of solar cell is less; It only converts 30-40% of energy incident on it
to electrical energy.
Need to use solar energy :
Pollution free
Maintenance free
Silent Operation
Long Life time.

4. 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 a operating point at which maximum power can be extracted from the
system. Usually represented as MPP.
The output of solar module is a function of solar irradiance, temperature.
Generally MPPT is installed in between PV system and load. Coupling to the
load for maximum power transfer may required either providing a higher voltage
at lower current or lower voltage at higher current.

5. Mechanical and Electrical Component :
SST89E516RD ( Series Microcontroller )
11.0592 MHz Crystal and 33pf Capacitor ( Max. frequency 12 MHz )
7805 / 7806 / 78XX ( Voltage regulator )
1000 Micro-farad capacitor
10 Micro – farad Capacitor
Pull up resistor network ( Used for Interfacing any IC )
ADC MCP3208 ( 12-bit Analog to Digital Converter )
ULN 2003 ( More than 5V )
MAX-232 ( 5V DC )
LM2596S Buck Module ( DC-DC buck module, Switching frequency – 150
KHz )
Relay Board ( Controlling Relays, Relay status indicating LEDs, Diodes,
Resistors )
Solar Plate ( Up to 21V, Rated Power 5W, Tolerence ±3 %, Temp 25 ̊C )
Battery – Accuplus+ + ( Up to 12V , 0.39A , Lead Acid Type )
LED ( DC 12V )

6. Block Diagram :
How Does MPPT Works :
PV panel ( solar panel ) takes solar energy from sun and converts to
electrical energy.
In essence, sunlight on a solar cell creates a small battery with voltages
typically to 0.5 V

7. Buck Converter :
A buck converter (step-down converter) is a DC-to-DC
power converter which steps down voltage (while stepping up current) from its
input (supply) to its output (load).
Boost Converter :
A boost converter (step-up converter) is a DC-to-DC power converter that
steps up voltage (while stepping down current) from its input (supply) to its
output (load).

9. Advantages :
MPPT method can extract maximum available
power from the PV module.
This can increase the tracking efficiency.
Up to 30% increased charging efficiency.
If your energy use is greater in the winter (
typically in most homes ) and you have cold
winter weather, then you can gain a substantial
boost in energy when you need it most!

10. Conclusion :
PV system getting more significance due to and load for impedance
shortage and environmental impact of matching conventional fuels
works good under rapidly changing environment condition and also achieves
Controlled MPPT PV system a decrease in oscillation at MPP.
This results in low operational life of the battery.
Future work :
Fast switching components are necessary to operate the device intended for
solar system racing. The component choice is key in the design of the MPPT.
High power efficiency is attained by systematically researching and selecting
the right components.
