2. INTRODUCTION
 Now a days there is a necessity for large amounts of
energy and the sources to produce these energies are
decreasing day by day.
 Solar is the way people are looking to these days.
 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.

3. What is Solar Energy?
Solar energy refers to energy
from the sun.
 It is the most important
source of energy for life forms.
The main benefit of solar
energy is that it does not
produce any pollutants and is
one of the cleanest source of
energy.
 It is a renewable source of
energy.

4. WHY
SOLAR
ENERGY?
DEMAND FOR SOLAR ENERGY

5. How much
solar energy?
The surface
receives about 47%
of the total solar
energy that reaches
the Earth. Only
this amount is
usable.

6. 3 WAYS TO CONVERT SOLAR TO
ELECTRICAL ENERGY
1. Solar Photo-Voltaic Cell(PV-cell):-Use solar PV-Cell to
generate electricity by formation of electron-hole pairs.
2. Solar Thermal Energy:-Use solar energy in the form of heat
to generate steam and run steam turbines.
3. Use solar energy to get fuels for energy generation:-Use solar
energy to split water into hydrogen and oxygen and use them
as fuel in H2-O2 fuel cell.

7. SOLAR TREE
(A smarter way to produce solar energy)

8. SOLAR TREE USES SOLAR
PV-CELL TO GENERATE
ELECTRICITY

9. WHAT IS A 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.
TREE stands for
 T= TREE GENERATING
R=RENEWABLE
E=ENERGY and
E=ELECTRICITY
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

10. COMPONENTS OF SOLAR TREE
 Solar panels
 Long tower
 Batteries
 Stems for connecting
the panels

11. SPIRALLING PHYLLOTAXY
It is the unique technique used so as to make sure that
every cell gets equal amount of solar energy.
This has been mainly implemented so as to increase the
efficiency of the plant.

12. WHY SOLAR TREES??
Due to less land requirement
Efficient energy generation
It can collect energy from wind
Why Should
we think
about it??

13. APPLICATIONS OF SOLAR TREE
 Street light.
 House supply.
 Industrial power supply.
 Continuous power supply.
 Charging slots for cars.
 Wireless Data transmission.

14. ADVANTAGES AND
DISADVANTAGES
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.
 DISADVANTAGES:-
 Cost is high.
 May cause hazards to the birds and insects.
 Hazards to eyesight from solar reflectors.

15. Final Thought
Goal is to decrease our dependence on fossil fuels
so use alternate methods.
Currently, 75% of our electrical power is generated
by coal-burning and nuclear power plants.
Mitigates the effects of acid rain, carbon dioxide,
and other impacts of burning coal and counters
risks associated with nuclear energy.
Pollution free, indefinitely sustainable.
