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.

What is Solar Energy?Solar energy refers to

energy from the sun. It is the most important source of energy for life forms.The main benefit of solar energy is that it does not produce any pollutants and is one of the cleanest source of energy. It is a renewable source of energy.

WHY SOLAR

ENERGY?

DEMAND FOR SOLAR ENERGY

How much solar

energy?

The surface receives about

47% of the total solar

energy that reaches the Earth. Only

this amount is usable.

3 WAYS TO CONVERT SOLAR TO ELECTRICAL ENERGY

1. Solar Photo-Voltaic Cell(PV-cell):-Use solar PV-Cell to generate electricity by formation of electron-hole pairs.

2. Solar Thermal Energy:-Use solar energy in the form of heat to generate steam and run steam turbines.

3. Use solar energy to get fuels for energy generation:-Use solar energy to split water into hydrogen and oxygen and use them as fuel in H2-O2 fuel cell.

SOLAR TREE

(A smarter way to produce solar energy)

SOLAR TREE USES SOLAR PV-CELL TO

GENERATE ELECTRICITY

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.TREE stands for T= TREE GENERATING R=RENEWABLE E=ENERGY and E=ELECTRICITYSolar 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

COMPONENTS OF SOLAR TREE

Solar panels Long tower Batteries Stems for connecting the panels

SPIRALLING PHYLLOTAXY

It is the unique technique used so as to make sure that every cell gets equal amount of solar energy.This has been mainly implemented so as to increase the efficiency of the plant.

WHY SOLAR TREES??

Due to less land requirementEfficient energy generationIt can collect energy from wind

Why Should we

think about it??

APPLICATIONS OF SOLAR TREE

Street light. House supply. Industrial power

supply. Continuous power

supply. Charging slots for

cars. Wireless Data

transmission.

ADVANTAGES AND DISADVANTAGES

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.

Final ThoughtGoal is to decrease our dependence on fossil fuels so use alternate methods. Currently, 75% of our electrical power is generated by coal-burning and nuclear power plants.Mitigates the effects of acid rain, carbon dioxide, and other impacts of burning coal and counters risks associated with nuclear energy.Pollution free, indefinitely sustainable.
