Now a days oil supply is decreasing therefore
energy source are becoming limited throughout the
The technology of using Bio-fuel is an alternate
solution of energy sources, but if we think that all the
world’s vehicle will be powered by bio fuels then the
amount of land used for farming must be doubled.
The thermal power plant produce energy but this
plant pollute to atmosphere. In all this Solar Tree proves
to be most beneficial source of energy for present and
This paper presents Solar Tree implementation as
Solar energy is the best option
Solar tree sounds like perfect solution for our
future energy needs
A solar tree is an artificial tree with nanowire
based solar cells arranged in Fibonacci series
Uses multiple number of solar panels which
forms the shape of a tree
CHOICE OF TOPIC:
It’s infinitely renewable
It can also increase your home’s
In 1800 solar energy plants developed.
In1839 ‘Alexandre Edmond’ discovered photo
In 1941- ‘Russell ohl’ inverted solar cell.
Solar tree foundation which began in 2008 by
In 2012 Ross Lovegrove designed the solar tree.
Designed a solar tree using an array of solar panels
of nanowire solar cells as leaves.
The solar cells on the tree were able to store
enough electricity inspite of receiving no direct solar
light for days at a time because of the clouds.
We planned to design green stems constructed of
steel pipes supporting a light bulb in which solar cells
In place of branches we use solar panel which has
to produce voltage.
Fig 1: solar tree
In area point
of view, solar
tree is more
The design copied from the pattern of coconut tree
as closely as possible. Battery is hidden at the ground
base which is closed with proper material.
The branch of the solar tree was decorated with
LED lights at the tip.
Idea of a device of installing a tall metallic pole of 50
to 70 feet height mounted on a basement of (2 X 2) Sqft
area, which will hold all the required panels on its body
like a tree.
The Fibonacci Sequence Solar Tree is one of
advanced solar tress and shown in given fig 3.
Fibanacci Sequence .
The plants follow a new growth pattern know as
Fibanacci Sequence. This pattern shows that in
sequence the previous numbers are added together to
make the next number(1+1=2, 2+1=3, 3+2=5, 5+3=8 &
etc.,) and in natural number.
Therefore, surface land is used only a maximum of
4 to 5 Square feet.
Of course, it needs some base foundation for
holding the taller pole but most of the foundation work
will be below the ground surface
TREE Stands For:
T – Tree generating
R - Renewable
E - Energy and
E - Electricity
NANOWIRE BASED SOLAR CELL:
Nano wires are made of semiconductor material
Indium phosphate- Commonly used as substrate for
Superior electron velocity, used in high-power
and high-frequency applications.
It works like antenna that absorb sunlight and
Nanowire crystal has cylindrical structure with
diameter of about 10,000 part of a human hair.
WORKING OF SOLAR TREE:
Storing of electric energy is a major problem for
all electric power system. Ways to eliminate solar
cell output fluctuations caused by the day and night
cycle and weather shifts.
Despite of energy loss, which can be high as
50% with present batteries. Solar tree panels charge
batteries during the day.
At dusk the solar tree automatically switches ON
The internal control can also regulates the
amount of light produced on how much charge is left
in the batteries.
E= Energy (kWh)
A=total solar panel area (m)
r = solar panel yield or efficiency (%)
H = Annual average solar radiation on title
PR = Performance ratio, coefficient for losses

SOLAR DATA COLLCETION
In the field of Golf courses and resorts
In Urban and Rural Areas
Applicable in city park and street light
Applicable on Airports
In Mountainous regions
Applicable on Highways
In De-forested areas
No air pollution
We wouldn’t have to worry as much about
future energy sources
People in poor country would have access
People can save money
Land requirement is very less
The solar new technology presented in this
paper will provides nearly high efficiency.
The number of papers and patents published in
this area has grown up exponentially over the last 10
Nanowire can concentrate the sunlight up to 15
times of the normal sunlight intensity
hence the surprising results have the potential for
developing a new kind of highly efficient solar cell.
