Definition of problem
Work distribution of project
Today’s time solar cells are becoming extremely popular
for utilizing solar energy to use in different ways such as
producing electricity, transportation,cooking etc .
So many solar panels have been
installed all over the
world and most of them are stable. They are installed in
the direction of maximum radiation of sunlight.
Now the problem arises that the sun is moving .So we
cannot use maximum radiation of sun all the time. The
position of maximum radiation receiving position only
comes once in 24 hours.
Solar tracker is the best solution for receiving
By moving the solar panel according to the
movement of sun we can always receive the
maximum radiation .
• The earth receives 16 x 1018 units of energy
from the sun annually, which is 20,000 times
the requirement of mankind on the Earth.
• Solar panels are used to convert light energy
into electrical energy.
Efficient Solar Power generation System
using moving panel is a efficientpower
generating system using sun light.
Two sensors in two directions to sense the
direction of maximum intensity of light. The
difference between the outputs of the sensors
is given to the microcontroller unit.
Microcontroller is used to
process the input
voltage from the comparison circuit and control
the direction in which the motor has to be rotated
so that it will receive maximum intensity of light
from the sun.
The power generated from this process is then
stored in a lead acid battery.
Stored energy is used to run different appliances
It consist of a LDR sensor senses max solar power
which is being given to the Microcontroller through
the ADC which digitizes the LDR output.
Controller then takes the decision according to then
algorithm and tilts the panel towards the direction of
the max energy given by LDR with the help of DC
The Motor is used to rotate the LDR to sense the
max solar power.
On the monitoring station which receives the data send
by the system.
This data is logged into the PC.
RS232 converter is used to connect the
microcontroller to PC which convert PC"s CMOS level to
Controller"s TTL level n vice versa.
Limit sensors or Touch sensors are provided to sense the
starting and ending position of the solar panel.
Keypad is provided to adjust the starting position of the
CMOS 8-bit microcomputer

Consists array of solar panels, an inverter, and
sometimes a battery and or solar tracker and
The efficiency of a panel determines the area of
• electromechanical device which converts electrical
pulses into discrete mechanical movements. The speed
of the motor shafts rotation is directly related to the
frequency of the input pulses and the
length of rotation is directly related to the number of input
Lead Acid Battery• very low energy-to-weight ratio and a low energy-to-
volume ratio, their ability to supply high surge
currents means that the cells maintain a relatively
large power-to-weight ratio. These features, along with
their low cost, make them attractive for use in motor
vehicles to provide the high current required
by automobile starter motors.

Emergency battery backup
To improve the sun tracking, a stand alone sun
tracker can be designed using 18 seriesPIC
In 18 series PIC microcontroller, data can be stored
periodically in MMC card .We need not to do it
manually (no need of rotation).
