INTRODUCTION
 solar energy is the best option.
 Solar tree sounds like the perfect solution
for our future energy needs.
 A solar tree is an artificial tree with
photo-voltaic cells arranged in Fibonacci
series manner.
 Uses multiple no. of solar panels which
forms the shape of a tree.

5. HISTORY
1. In 1800 solar energy
plants developed .
2. In 1839 Alexandre
Edmond discovered
the photo voltalic effect.
3. In 1941 Russell ohl
invented solar cell .
4. Solar Tree Foundation
which began in 2008 by
Rein Triefeldt
5. In 2012 Ross
Lovegrove designed
the solar tree.

WHAT IS SOLAR TREE
A solar tree is a decorative means of producing solar energy
and also electricity. It uses multiple no. of solar panels which
forms the shape of a tree. The panels are arranged in a tree
fashion in a tall tower/pole.
TREE stands for
T= TREE GENERATING
R=RENEWABLE
E=ENERGY and
E=ELECTRICITY
This is like a tree in structure and the panels are like leaves of
the tree which produces energy.

COMPONENTS OF SOLAR TREE
The solar tree consists of mainly five parts to design.
 Solar panels
 Long tower
 LEDs
 Batteries
 Stems for connecting the panels

 Tree can produce their own food material by the process
called PHOTOSYNTHESIS.
 Leaves are producing food materials for human beings.
 Likewise in solar tree solar plates are producing energy
for the society.
WHY WE CALLED IT AS SOLAR TREE

HOW SOLAR PANELS WORK?
Photovoltaic cell converts sunlight
into electric energy and this effect is
known as photovoltaic effect.
Solar cells essentially create
electricity by converting photons of
light into electrons.
Solar cell producing direct current,
or DC, this DC current is converted to
alternating current, or AC by using
inverter.

ADVANTAGES OF SOLAR
PANEL
 Ecologically Friendly
 Decreased Electrical Bill
 Low Maintenance
 Efficiency

13. 13
NEED OF SOLAR TREE
 Due to less land requirement
It require less land as compare to traditional PV system. So we
require such a plant which can generate max. energy
using minimum land.
 Efficient energy generation
It can generate energy very efficiently as compare to
traditional system.
 It can collect energy from wind
The stem are flexible so that they can rotate in any
direction and by shaking themselves they produce
energy also from wind as in the case of a natural tree.

14. 14
WHY IT IS BETTER THAN A TRADITIONAL SYSTEM
 For the traditional system we
require large size of land
Example –To generate 2 MW
power from a pv module we
requires 10 -12 acres of land
for housing of panels only.
 For the same amount of energy
we require only 0.10-0.12
acres of land in case of solar
tree.

SOLAR TREE IN INDIA
 India being a developing country and highly populated requires
a power plant where maximum energy can be generated by
using minimum land.
 We must try to produce energy from sun by using solar tree in
our country to increase our per capital and and fulfil the
growing energy demand.

16. 16
 The Salient Features of the Solar Power
Tree are:
• It takes only 4 square feet of land for a 5
KW Solar Power tree, whereas in a
conventional layout, it requires 400 square
feet of land.
• By holding the photovoltaic panels at a
higher height, on an average it gets more
sunrays for one hour in a day. As a result,
it is possible to harness 10-15% more power
in comparison to a conventional layout on
ground.
• It has a battery back-up of 2 hours on full
load, hence giving light even after sunset.
• It is facilitated with water sprinkler at
the top for self-cleaning of panels, that
increases the efficiency of the solar panels.
• The estimated cost of the device is
around Rs. 5 Lakh for a 5 KW
specification.

18. APPLICATION
 Street light
 House supply
 Industrial power supply
 Mobile charger

19. 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
 People can save money
 Land requirement is very less

20. DISADVANTAGES
As we know nothing is perfect in the world, so is Solar
tree.
Here are some of its disadvantages
 Cost is high
 May cause hazards to the birds and insects
 Hazards to eyesight from solar reflectors

21. 21
FUTURE OF SOLAR TREE
We can charge our electrical vehicles and also
enrich the environment with eco-friendly solar
trees.
Getting electrical power instantly

22. 22
CONCLUSION
 To fulfils the increasing energy demand the people.
 Saving of land, this project is very successful one.
 This can provide electricity without any power cut
problem.
