INTRODUCTIONNow a days with the growing population and there is a necessity for large amounts of energy and the sources to produce these energies are decreasing day by day.

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. In 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 . In this case solar tree could be the best one for us .

WHAT IS ENERGY??

•  Energy is a property of objects, transferable among them via fundamental interactions, which can be converted into different forms but  not created or destroyed. 

IT IS OF TWO TYPES:-

1. RENEWABLE ENERGY

2. NON-RENEWABLE ENERGY

.

Solar energy is radiant light and heat from the sun harnessed using a range of ever-evolving technologies such as solar heating, solar photovoltaic, solar thermal energy, solar architecture and artificial photosynthesis.

What is solar energy?

Benefits of solar energy

DEMAND FOR SOLAR ENERGY

HISTORY1. In 1800 solar energy

plants developed .2. In 1839 Alexandre

Edmond discovered the photo voltaic 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.

 SOLAR TREE??As we know trees are present in nature and

they can produce their own food material by the process called PHOTOSYNTHESIS.

By this process they are indirectly providing food to the human society because we are depending on the green plants for our food directly or indirectly.

Solar tree: This is a tree in which the stems connected acts as the branches of the tree and the solar panels are like the leaves

Green leaves are producing food materials for human beings likewise this leaves are producing energy for the society. So it is very appropriate to called it as a tree.

COMPONENTS OF SOLAR TREE

The solar tree consists of manly five parts to design.

Solar Panel

Long tower

LEDs

Batteries

Stems

DESIGN •Designed a solar tree using an array of solar panels of solar cells as leaves. •The solar cells on the tree were able to store enough electricity . • We planned to design green stems constructed of steel pipes supporting a light bulb in which solar cells are connected.

• In place of branches we use solar panel which has to produce voltage. •Battery is hidden at the ground base which is closed with proper material.

• The branch of the solar tree was decorated with LED lights at the tip.

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.

EQUATION:

E=A*r*H*PR

where, E= Energy (kWh) A=total solar panel area (m) r = solar panel yield or efficiency (%)  H = Annual average solar radiation on title panels PR = Performance ratio, coefficient for losses (range between 0.5 and 0.9, default value = 0.75)

            

 

          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 .

WHY IT IS BETTER THAN A TRADITIONAL SYSTEMFor 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.

It require less land as compare to traditional PV system. So we require such a plant which can generate max. energy using minimum land. It can generate energy very efficiently as compare to traditional system.

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.

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.

Solar tree sounds like the perfect solution for our future energy needs. 

Solar tree is a revolutionary urban lighting concept.The tree design made 50% more electricity and the collection

time of sunlight was up to 50% longer. it helps the environment, saves money, cheap to use and you

can have them on your homes .It’s free and last for lifetime and  environment friendly.
