1. 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. ln 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 . lo this case solar tree could be the best
one for us . We can also use the technique called "SPIRALLING
PHYLLATAXY" to improve the efficiency ofthe plant.

2. WHAT- IS-SOT,AR ~RE
~
E
~~
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=ELECTRJCITY
This is like a tree in structure and the panels are like leaves of
the tree which produces energy.

3. COMPONENTS OF SOLAR TREE
The solar tree consists ofmainly five parts to design.
Solar panels
• Long tower
• LDEs
• Batteries
Stems for connecting the panels

4. SPIRALLING PHYLLATAXY
• It is a technique used in designing ofsolar 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.

5. ~~~~
wiiYWE CALLED IT AS SOLA R-TREE
1 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.

6. How Solar P-anels Woi;k?~ ~~~:::
► 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.

7. 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 energygeneration
It can generate energy very efficiently as co1
mpare 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 ofa natural tree.

8. Advantages of Solar Panel
c Ecologically Friendly
• Decreased Electrical Bill
• Low Maintenance
• Efficiency

9. WHY~IT IS BETTER-l=HAN A J.RADITIONA~
~ TEM
• 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 ofsolar tree.
Traditional solar system
Solar tree

10. APPLICATION
Street light
• House supply
Industrial power supply

11. 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.
c 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.

12. ADVANTAGES
c. No air pollution
, We wouldn't have to worry as much about future
energy sources
0 People in poor country would have access to electricity
• People can save money
c Land requirement is very less

13. DISADVANTAGES
• Cost is high
• May cause hazards to the birds and insects
• Hazards to eyesight from solar reflectors

14. CONCLUSION
To fulfils the increasing energy demand the people.
c 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.
