INTRODUCTION





Solar energy is available in abundance and considered as
the easiest and cleanest means of tapping the renewable
energy.
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.

HISTORY





In 1800 solar energy
plants developed .
In 1839 Alexander
Edmond discovered the
photo voltaic effect.
In 1941 Russell ohl
invented solar cell .
Solar Tree Foundation
which began in 2008 by
Rein Triefeldt
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

WHY WE CALL IT AS SOLAR TREE



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.

TECHNIQUES USED
SPIRALLING PHYLLATAXY is a technique used in
designing of solar tree .
 It provides the way to help the lower panels from the
shadow of upper ones, so that it can track maximum
power from sun.

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.

NEED FOR 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.

13
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 capita land and fulfil the
growing energy demand.
15
SALIENT FEATURES OF SOLAR TREE

The Salient Features of the Solar 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.

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
19
ADVANTAGES SOLAR TREE

Ecologically Friendly

Decreased Electrical Bill

Low Maintenance

Efficiency

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