4. NECESSITY
As there is an increasing demand for the
renewable energy day by day there is a much
scope of utilizing the natural renewable
energy resources in an effective way…….
In this context the SOLAR TREE is a new
innovation in utilizing the solar energy in an
effective way.

5. WHAT IS A SOLAR TREE???
Solar tree is the
hybrid module
combining artistic
and the solar PV
technology to
produce electricity
with less
utilization of
surface land…….

6. PHOTOELECTRIC EFFECT
Photoelectric effect is a process in which
when two dissimilar materials(P and N
type semiconductor materials) placed
close together produce an electrical
voltage when stuck by light or radiant
energy.

7. PHOTOVOLTAIC (PV) CELL
Photovoltaic or PV cell has a p-type and
an n-type semiconductor layer placed
close enough forming a p-n junction.

8. SOLAR (OR) PV CELL

9. SOLAR CELL, MODULE AND ARRAY
A group of cells is
called as a Module
A number of
modules together
called an Array

10. SOLAR TREE

11. SPIRALLING PHYLLATAXY
 Solar trees are
constructed keeping in
view that each and every
plate must receive
maximum light so that
maximum efficiency of
the tree can be obtained.
This design
technique is known as
SPIRALLING PHYLLATAXY.

12.  A solar tree consists of a
strong metallic pole base
with less base area.
 From this base the pole
is erected to a height so
that the plates can
receive a good extent of
sunlight but keeping in
view of the mechanical
balancing of the pole.
 The solar plates being a
major part of the tree are
then placed as branches
of the tree at this height.

13. ROSS LOVEGROVE’s SOLAR TREE
 Ross Lovegrove, an
industrial designer
known for his organic
inspired designs,
conceived an organic-
looking solar structure
with multiple curve
stems and circular
collections of
photovoltaic cells. This is
made of steel pipes.

14.  Ross Lovegrove has
designed this solar
tree provided with
some LED’s.
 The batteries charge
whole day time with
the electricity
produced and when it
becomes dark the
LED’s switch on and
provides light in the
night combined by
the beauty of its
elegant design.

15. INDIAN MODEL BY CSIR-CMERI
 Central Mechanical
Engineering Research
Institute(CMERI), a
constituent of Council of
Scientific and Industrial
Research(CSIR) has
developed a solar power
tree and has been
inaugurated by the
Central Minister for
Science and Technology
Dr. Harsh Vardhan on
21st May, 2016.

16. ADVANTAGES:
 Land requirement drastically reduces.
 No pollution.
 No worry about the future energy resources.
 Conventional energy sources can be effectively saved.
 Produce electrical energy at any place where there is
effective lighting.
 People in poor continent like Africa can also have an
access to electricity with this scheme.
 Due to the elevation, on an average it can get more
sunrays for 1 hour in a day.

17. DISADVANTAGES:
 Eyesight is effected due the solar plate glass reflectors.
 Initial installation cost is quite high than the
conventional system.

18. APPLICATIONS:
 Industrial power supply.
 Street lighting.
 Vehicle parking areas can be effectively utilized by
erecting such solar trees which produces electricity
and also provide shade to the vehicles.
 These trees are used in developed countries to provide
public charging slots for mobiles, laptops and other
electronic gadgets.

20. SOLAR TREE STREET LIGHTING:

21. STRAWBERRY TREE:

22. CONCLUSION:
To fulfill the growing demand of
utilizing the non-conventional energy sources in an
effective way this model is successful one. Less land
requirement makes it the best option to choose
among the solar energy utilization techniques. Hence
this model has a good future scope of development in
densely populated countries like India where less land
is required to be utilized for supplying more energy.
