The document discusses a seminar presentation on solar trees. It begins with an introduction to solar energy and its benefits. It then defines a solar tree as a structure that uses multiple solar panels arranged like a tree to produce solar energy and electricity. It discusses the components, types, manufacturing technologies like spiralling phyllotaxy, applications, advantages like reduced land usage, and disadvantages of solar trees. The conclusion emphasizes that solar trees can help meet increasing energy demands while saving land.

3. Now a days with the growing population and energy demand we should take a
renewable option of energy source and also we should keep in mind that energy should
not cause pollution and other natural hazards. In this case the solar energy is the best
option for us.
India is a highly populated country , so we should take the advantage of such an energy
which requires a very less space to produce energy efficiently . In this case solar tree
could be the best one for us . We can also use the technique called “SPIRALLING
PHYLLATAXY” to improve the efficiency of the plant .
INTRODUCTION

4. WHAT IS SOLAR ENERGY?
Solar energy is radiant light and heat from the sun harnessed
using a range of ever-evolving technologies such as solar
heating, solar photovoltaic, solar thermal energy, solar
architecture and artificial photosynthesis.
It is an important source of renewable energy and its
technologies are broadly characterized as either passive solar or
active solar depending on the way they capture and distribute
solar energy or convert it into solar power. Active solar
techniques include the use of photovoltaic systems,
concentrated solar power and solar water heating to harness
the energy. Passive solar techniques include orienting a
building to the Sun, selecting materials with favorable thermal
mass or light dispersing properties, and designing spaces that
naturally circulate air.

5. BENEFITS OF SOLAR ENERGY…

6. 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.

7. SOLAR TREE
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.

8. SOLAR TREE
As we know trees are present in nature and they can produce their own food material by the
process called PHOTOSYNTHESIS.
By this process they are indirectly providing food to the human society because we are
depending on the green plants for our food directly or indirectly.
Solar tree: This is a tree in which the stems connected acts as the branches of the tree and the
solar panels are like the leaves.
That’s why it is called as tree.

9. BLOCK DIAGRAM

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

11. In this diagram, the arrows show the flow of current. The solar trees provide the
energy, which is fed into the solar controller. The solar controller charges the
batteries. The controller also supplies power to the low-voltage devices using
either the solar trees or batteries as the source of power.
The AC power takes its power directly from the battery and provides the high-
voltage power supply.
TYPES OF SOLAR TREE
 System containing single tree

12. The diagram above shows a grid-tie system using micro-inverters. It is similar to
the first diagram, except that each tree is connected to its own inverter, and the
inverters themselves are dais-chained together, converting the low-voltage DC
power from each tree into a high-voltage AC power supply.
 GRID TIE SYSTEM

13. MANUFACTURING TECHNOLOGIES
 Spiral phyllotaxy
 Cyclic phyllotaxy
 Verticillate phyllotaxy
Opposite phyllotaxy

14. SPIRALLING PHYLLATAXY
 It 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.
 This technology is used to
improve the efficiency of the
plant
 It is the unique technique used so
as to make sure that every cell gets
equal amount of solar energy

15. WHY IT IS BETTER THAN 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.

16. NEED OF SOLAR TREE
 Due to less land requirement
 Efficient energy generation
 It can collect energy from wind
 It’s infinitely renewable

17. NEED OF 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
IIT Kanpur is the only place in India where you can find
 solar trees.
RECENTLY IN 2016 Council of Scientific and Industrial Research (CSIR) in New Delhi,
whose laboratory in Kolkata developed a soler tree.

18. APPLICATIONS
 Street light.
 House supply.
 Industrial power supply.
 Charging slots for cars.
 Wireless Data transmission
 E-tree

19. ADVANTADE OF SOLAR TREE
 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
 Ecological friendly

20.  Cost is high
 May cause hazards to the birds and insects
 Hazards to eyesight from solar reflectors

21.  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.
 The extra energy can be provided to the grid
 The main aim of this project is uplifting the public opinionon R E S.
