For guys those who want funky projects relating to Solar Energy. This is a must glance project.

1. Design and Implementation of
technique of maximum power
utilization of Solar Panel
- HITAM EEE Students

2. The „solar position control system‟ is a
most advanced embedded based project.
 Nowadays we are observing much increase
in the power tariff and due to this increase,
a common man is unable to bear such
rates.
 This project titled as “Design and
Implementation of technique of maximum
power utilization of Solar Panel” to develop
a system through which we can save the
power.


3. 

Normally we glance in shopping malls,
theaters and House appliances and
conference halls and at any other places they
are using the source like generators along
with the main power supply as a backup, but
they are expensive.
That‟s why by using the solar power we can
generate power economically and this is a
natural power so there is no reduction in the
source of power production and also no
power wastage in this system.

4. 

In normal solar panel we can get the power
only in one direction, so we are unable to
fully utilize the natural resource with this
system.
That‟s why a
system is being developing through our
project which we can get the power in all
directions on rotating the panel according to
the sun position.
Through this system we can increase the
output power than normal system.

5. 

For this one stepper motor is connected to
solar panel. Sun light absorbers (LDRs)
are connected in the circuit according
to change in position of the sun.
When corresponding LDRs observe
the sunlight. The output of LDR is in analog
form.
Microcontroller accepts only digital form.

6.  In
this we are interfacing another A/D
Converter device to convert the generated
analog signal to digital form and to send it
to microcontroller.
 Finally
all LDRs value is compare and selects
the LDR of giving more brightness and
stepper motor will turn on and moves the
solar panel to the position of the
corresponding LDR.
By this process we can get the more power.

13. DESIGNING:
In order to fulfill this application there are
few steps that has been performed i.e.
Designing the power supply for the entire
circuitry.
 Selection of microcontroller that suits our
application.

Complete studies of all the above points are
useful to develop this project.

14. POWER SUPPLY SECTION:
In-order to work with any components basic
requirement is power supply. In this section
there is a requirement of different voltage
levels.

15. 
Microcontroller

A/D Converters

Many other peripherals like LED, LDR‟s, relays.

16. In order to fulfill our application basic that is
AT89C51 controller is enough. But still we selected
AT89S52 controller because of inbuilt ISP (in
system programmer) option.

There are minimum six requirements
for proper operation of microcontroller.
 power supply section
 pull-ups for ports (it is must for PORT0)
 Reset circuit
 Crystal circuit
 ISP circuit (for program dumping)
 EA/VPP pin is connected to Vcc.


A microcontroller (sometimes
abbreviated µC, uC or MCU) is a small computer on
a single integrated circuit containing a processor
core memory, and programmable
input/output peripherals.
Microcontrollers are designed for embedded
applications, in contrast to
the microprocessors used in personal computers or
other general purpose applications.
By reducing the size and cost compared to a design
that uses a separate microprocessor, memory, and
input/output devices, microcontrollers make it
economical to digitally control even more devices
and processes.

18. 


Microcontrollers usually contain from several to
dozens of general purpose input/output pins
(GPIO).
GPIO pins are software configurable to
either an input or an output state. When GPIO pins
are configured to an input state, they are often
used to read sensors or external signals.
Configured to the output state, GPIO pins can drive
external devices such as LEDs or motors.
Microcontrollers were originally programmed only
in assembly language, but various high-level
programming languages are now also in common
use to target microcontrollers.

19. MOTOR DRIVER CIRCUIT
 L293D is a dual H-bridge motor driver IC.
Motor drivers act as current amplifiers since
they take a low-current control signal and
provide a higher-current signal.
 It contains two inbuilt H-bridge driver
circuits.
In its common mode of operation, two DC
motors can be driven simultaneously, both
in forward and reverse direction. The
motor operations of two motors can
be controlled by input logic at
pins 2 & 7 and 10 & 15.

20. It is economical and natural power, less power wastage
in this system.
 Solar energy is clean, renewable (unlike gas ,oil and
coal )and sustainable, helping to protect our
environment.
 The
solar tracker system provides numerous
applications in the field of industrial, infrastructural as
well as agricultural sectors, both private and public
purposes.
 Its main application lies in the industrial processes like
energy stations and powerhouses for the production of
electricity. Moreover, it also find its applications in pool
filtration systems, in agriculture for irrigation methods
and solar water heating systems
