The document discusses a solar tree designed using nanowire-based solar cells, aimed at providing a clean and renewable energy source as traditional energy resources decline. It outlines the history, design principles, working mechanisms, and advantages of solar trees, along with potential applications in various environments. The solar tree employs a Fibonacci sequence structure to maximize energy efficiency while minimizing land use.

3. ABSTRACT:
 Now a days oil supply is decreasing therefore
energy source are becoming limited throughout the
world.
 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
future world.
 This paper presents Solar Tree implementation as

4. INTRODUCTION:
 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
manner
 Uses multiple number of solar panels which
forms the shape of a tree

5. CHOICE OF TOPIC:
 It’s free
 It’s clean
 It’s infinitely renewable
 It can also increase your home’s
value

6. HISTORY:
 In 1800 solar energy plants developed.
 In1839 ‘Alexandre Edmond’ discovered photo
voltaic effect.
 In 1941- ‘Russell ohl’ inverted solar cell.
 Solar tree foundation which began in 2008 by
‘Rein Triefeldt’.
 In 2012 Ross Lovegrove designed the solar tree.

7. DESIGN:
 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
are connected.
 In place of branches we use solar panel which has
to produce voltage.

 In area point
of view, solar
tree is more
efficient and
much better
than the
traditional Solar
system.

9. Conti….
 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.

10. Conti…
 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

11. TREE Stands For:
 T – Tree generating
 R - Renewable
 E - Energy and
 E - Electricity

12. NANOWIRE BASED SOLAR CELL:
 Nano wires are made of semiconductor material
Indium phosphate- Commonly used as substrate for
epitaxial InGaAs.
 Superior electron velocity, used in high-power
and high-frequency applications.
 It works like antenna that absorb sunlight and
generate power.
 Nanowire crystal has cylindrical structure with
diameter of about 10,000 part of a human hair.

14. 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
its led.
 The internal control can also regulates the
amount of light produced on how much charge is left
in the batteries.

15. EQUATION:
 E=A*r*H*PR
where,
E= Energy (kWh)
A=total solar panel area (m)
r = solar panel yield or efficiency (%)
H = Annual average solar radiation on title
panels
PR = Performance ratio, coefficient for losses
(range between 0.5 and 0.9, default value =
0.75)

20. ADVANTAGES :
 No air pollution
 We wouldn’t have to worry as much about
future energy sources
 People in poor country would have access
to electricity

 Land requirement is very less

21. CONCLUSION:
 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
years.
 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.
