What is Solar Energy and its Harness Methods.

As we know that energy is needed to do the work , we have Traditional energy resources like oil, nature gas and coal,  these resources is called Fossil fuels and is not renewable resources . However fossil fuels have negative impact too.

Global warming

Acid rain

Toxic gases

 The best alternative we have is solar energy , which is a renewable energy resources .it provides unlimited steady supply through time. It has many benefits over the fossil fuels that make it one of the most promising energy form Eco-friendly or Non polluting and freely available worldwide

What is Solar Energy ?

It is the energy that is  produced by the sun in the form of heat and light. Solar Energy has been used by the people since ancient or very long time by using simple magnifying glasses to concentrate the light of the sun into beams so it get heated up cause catch fire.If you are already utilizing the Solar Energy, you can improve it and make it more efficient than the existing setup.

There are so many methods to convert the Solar Energy into electricity. solar energy is harnessed from the sun . It's main ways are :

 1. Photo voltaic systems (PV system)

2.Solar Water Heating

3.passive solar energy

4.Solar Thermal Electricity

5. Solar Heating  and cooling 

1.Photo voltaic system :-

This system is panel which is made up of material that , when exposed to the sun light , sunlight strikes on the panels then the migration of electron take place  through which electric current produce , is called photo voltaic effect .

2. Solar Water Heating:-

when the sunlight strikes on system it captures the it in order to heat the water in the passage to be used for baths, showers ,in kitchen etc.

It is usually  rectangular chamber with multiple small tube called flat plate collector which circulate water .

3.passive Solar Energy:-

Basically this system is used to heat and cool the the light living space. When sun light strike on the building , the building materials can reflect , transmit or absorb the solar energy or solar radiation.

4.Solar Thermal Electricity:-

In this system Solar Energy is concentrated on the fluid basically on the water , then hot water falls on the turbine to produce clean electricity.

5.Solar Heating and cooling:-

 In this system also the sunlight is strikes on the water , space cooling, heating and the same for commercial and industrial applications.

This system is used , where the huge amount  amount of energy is required like in office, industry and for the large building.

All the 5 conversion method will explain in details in the further article.
