SOLAR TREE TANJIR ALAMECE124007

INTRODUCTION

solar energy is the best option.Solar tree sounds like the perfect solution for our future energy needs. A solar tree is an artificial tree with photo-voltaic cells arranged in  Fibonacci series manner. Uses multiple no of solar panels which forms the shape of a tree.

DEMAND FOR SOLAR ENERGY

history1. In 1800 solar energy

plants developed .2. In 1839 Alexandre

Edmond discovered the photo voltalic effect.

3. In 1941 Russell ohl invented solar cell .

4.  Solar Tree Foundation which began in 2008 by Rein Triefeldt

5. In 2012 Ross Lovegrove designed the solar tree.

WHAT IS 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 and

E=ELECTRICITY

This is like a tree in structure and the panels are like leaves of the tree which produces energy.

COMPONENTS OF SOLAR TREE The solar tree consists of manly five parts to design.

Solar Panel.

Long tower.

LEDs.

Batteries.

Stems.

How Solar Panels Work?

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.

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.

WHY WE CALLED IT AS SOLAR TREE

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.

This technology is used to improve the efficiency of the plant .

Fibonacci seies:

Application of Fibonacci sequence in SOLAR TREE

Fibonacci Sequences in Trees:

0 1 1 2 3 5 8 13 21 34………

On the oak tree, the Fibonaccifraction is 2/5, which means that the spiral takes five branchesto spiral two times around the trunk to complete one pattern.Other trees with the Fibonacci leaf arrangement are the elm tree(1/2); the beech (1/3); the willow (3/8) and the almond tree(5/13) (Livio, Adler).

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 energy generation It can generate energy very efficiently as compare 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 of a natural tree.

WHY IT IS BETTER THAN A TRADITIONAL SYSTEM 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 of solar tree.

Traditional solar system

Solar tree

APPLICATIONS Street Light.

House Supply.

Industrial Power Supply.

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.

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.

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.

Saves money.

Land requirement is very less.

DISADVANTAGES

Costly.

May cause hazards to birds and insects.

Hazards to eyesight form solar reflectors.

CONCLUSION

To fulfils the increasing energy demand the people.

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.
