2. TYPES OF ENERGY SOURCES

3. 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.

4. HISTORY
• 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.

5. 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. The panels are arranged in a tree
fashion in a tall tower/pole.
TREE stands for -
T= TREE GENERATING
R=RENEWABLE
E=ENERGY
E=ELECTRICITY
This is like a tree in structure and the panels are like leaves
of the tree which produces energy.

6. PARTS OF A SOLAR TREE
• Solar Panel
• Long tower
• Inverter
• Batteries
• Stems

7. 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.

8. WHY IT IS BETTER THAN A TRADITIONAL SYSTEM
• To generate 2 MW power from a p v module we
requires 10 -12 acres of land for housing of panels only
but for the same amount of energy we require only
0.10-0.12 acres of land in case of solar tree.
Traditional system Solar tree

9. LARGEST SOLAR TREE
Present in London
23 feet tall , Consists 27 solar panels
Produces 8.6 KW of energy
Connected to Power grid

12. CSIR develops ‘solar tree’ that can
light 5 houses (case study)
• A CSIR laboratory in West Bengal has designed a ‘solar
power tree’ that takes up only four square feet of space
and produces about three kilowatts (kW) of power,
enough to power about five households.
• The three kW solar power tree resembles a tree with
branches at different tiers and could be squeezed on
rooftops and highways with a space requirement of
around four square feet.
• The branches hold up the 30 photovoltaic panels and the
system costs around Rs.3 lakh with battery back-up.

13. APPLICATIONS
• Street light.
• House supply.
• Industrial power supply.
• Continuous power supply.
• Charging slots for cars.
• Applicable on Airports
• Applicable on Highways
• In Deserts
• Private gardens

14. • TUMKUR DISTRICT
• 2000 MW CAPACITY
• 16500 crores investment
• 13000 acres

15. 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.
• This can provide electricity without any power cut
problem. The extra energy can be provided to the
grid.

16. Disadvantages
• Cost is high.
• May cause hazards to the birds and insects.
• Hazards to eyesight from solar reflectors.
• Reliability and Efficiency.

17. PORTABLE SOLAR TREE

18. INFERENCE
• Solar tree sounds like the perfect solution for
our future energy needs
• The tree design will produce 50% more
electricity .
• It’s free and last for lifetime and environment
friendly.
• It’s a Solution for 50% of villages in India which
will have very frequent power cuts.
