Introduction

• It is a form of renewable energy resource that is some

measure competitive with fossil fuels

• Solar energy is available in abundance and considered as the

easiest and cleanest means of tapping the renewable energy

• However the main problem associated with tapping solar

energy is the requirement to install large solar collectors

requires a very big space. Solar Botanic will introduce artificial

trees that make use of renewable energy from `the sun and

wind, they are an efficient clean and environmentally sound

means of collecting solar radiation and wind energy.

SOLARBOTANIC TREE

•

The Solar Botanic Energy Tree is a new generation of hybrid, low

cost, highly efficient, eco-friendly, aesthetically pleasing and

sustainable renewable energy system that incorporates advanced

nano-technologies to mimic natural tree designs and harness energy

from the sun, wind and rain in the process we call “Artificial

Photosynthesis”.

• Here at SolarBotanic, they have amassed a wealth of information

relating to SolarBotanic Trees and Nanoleaves and the field of

photovoltaic thermovoltaic and piezovoltaic technology

• Trees make use of light, heat and wind and turn it into useable

electricity for your home or car.

Why its named so ?

• Trees can produce their own food material by the process called

PHOTOSYNTHESIS they are indirectly providing food to the human

society

• Green leaves are producing food materials for human beings

likewise the solar panel leaves are producing energy for the society

Why a solar botanic tree

Due to less land requirement:• It is the best option of energy generation because it requires very

less land as compare to the traditional PV system

Efficient energy generation:• It can generate energy very efficiently as compare to traditional

system.Depending on size and location, a tree can produce between

2000 and 12,000 kWh per year.

Construction & Working

The solar tree consists of some important parts in its design. They are

as follows

• Nanoleaves

• Long tower

• LEDs

• Batteries

• Stems for connecting the nanoleaves

• Piezoelectric ribbons

WORKING:

• Batteries are charged during the day time and used for store the

energy and can use on cloudy days

• LEDs are automatically switched on

• These are used to indicate how much charge/energy remain left

NANOLEAVES

. A Nanoleaf is thin like a natural leaf, when outside forces, like the

wind pushes the Nanoleaf back and forth, When thousands of

Nanoleaves flap back and forth due to wind, millions and millions of

Pico watts are generated, the stronger the wind, the more energy is

generated.

• Nanoleaves only reflect a small part of the sunlight that strikes them

• also convert the invisible light, known as infrared light or radiation

• it converts this thermal radiation into electricity, even hours after the

sun has set.

Properties of nanoleaves

• (1) Light, scalable, robust structure

(2) Low cost

(3) Attractive bio-compatible design

(4) Easy installation, operation and maintenance

• The trunk is the part of the tree that connects the Nanoleaf

crown with its mounting roots. This allows the Nanoleaves to

harvest Solar Radiation andwind energy to produce electricity,

which is then transported down to the base of the trunk. The

trunk is made from environmentally friendly recycled

polymers

• The trunk is made from environmentally friendly recycled

polymers and synthetic resin to give it strength.

• The Petiole or leafstalk is incorporated with piezoelectric

ribbons

Better than a Traditional system

• For the traditional system we require large size of land to generate a

small amount of power. It requires about 1% land as compare to the

traditional system. And gives effinciency of over 84 %

• Example :To generate 2 MW power from a pv 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

APPLICATIONS

• Urban and Rural

• Recreational parks, city parks

• New housing estates

• Golf courses and resorts

• Mountainous regions

• Coastlines

• Highways

• Airports

• Deserts

• Penthouses, balconies, verandas

• Private gardens

• De-forested areas

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

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. Solar tree will be the best option

to avoid this problem.

CONCLUSION

• To fulfil the increasing energy demand the people and

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.
