What is solar energy?  

Solar energy is the most easily available source of energy. It is free in form and therefore no one owns it. Solar energy does not pollute the environment and the most unblemished source of energy.

What is the source of solar energy?

The sun is the source of solar energy, the most essential source of energy.  The heat and light energy that it radiates can be absorbed and transformed into electric energy and utilised for various activities and processes. It is free in form and therefore can be used abundantly. It’s a non conventional source of energy.

History

The utilisation of solar energy has existed since the pre-historic times. There have been efforts made to utilise solar energy in the most efficient way possible. Earlier most of the efforts were academic based and only for study purpose. But now, since the reform period the efforts are being applied to the practical life as well, as these efforts have proved to be cost effective.

Solar energy is cost effective in nature. Solar panels are used for transforming solar energy into various other forms of energy.

Solar panels are very useful and productive. Solar panels and various other solar devices absorb the heat and light energy from the sun throughout the day time and then help us meet our requirements as necessary. Solar energy can be transformed into electric energy, light energy etc.

Details or facts about solar energy:

Essential facts about solar energy are that, it is an energy which is harnessed from the heat or sunlight of the sun. This heat is utilized by various technologies such as solar powers, solar heaters, artificial photosynthesis, and various other contraptions in generating electricity. Solar energy is a renewal source of energy and has an unlimited supply. It is infinite, can be replenished and its supply would probably never run out.

Solar energy is basically of two types-

a) First is Solar photovoltaic (PV) –

They directly transform the radiance of the sun into operational energy through a PV cell which smothers a semi-conducting component,

b)  The second one is Concentrating Solar power (CSP) –

These assist in accumulating sunlight energy within a heat receiver transforming that sun’s heat into mechanical energy, and then finally into, solar thermal powered electricity.

Various facts about solar energy…

•   All life forms have been surviving on solar energy as it is the major source of energy.

•   The sun is 90 million miles away from the earth but it takes less than 10 minutes for the light energy to travel that distance and touch the earth surface. A free form of energy.

•   Solar energy utilisation is further categorised to active and passive technologies. Photovoltaic cells or panels and solar thermal panels are examples of active technology. The construction of rooms such that there is a favourable use of sunlight with improved air-circulation would be an example of passive technology.

•   Only 70% of the total sunlight is ingested in by the land, water and the clouds, the rest is cast back to the space.

•   Solar energy is also used in the process of photosynthesis. The chemical gas that is emitted during the process of photosynthesis helps in the making of the fossil fuels.

•   Solar energy is used in the creation of salt from the sea water, it is one of the oldest techniques that is being followed since the pre-historic period.

•   Photo-voltaic cells are used to convert solar energy into electric energy, the process is known as photoelectric effect. Concentrated solar power can also be used to for converting solar energy into electric energy.

•   Fossil fuels have been proved to be one of the major sources of energy to the world and solar energy helps in the creation of fossil fuels.

•   Solar energy can be used for domestic purposes as well using solar panels, they can be used for cooking, heating water and various other domestic purposes.

•   Solar energy is pollution free and it does not affect the environment in any harmful way.

•   Solar energy can be exploited into electric energy using various renewable energy techniques as it is the most extensively used renewable energy.

•   Spaceships have been using solar powers for various missions outside space by different countries, as sun is the only source of energy there.

•   Solar power plant covers around 1000 acres of land in Mojave desert in California. It happens to be the largest solar power plant in the world.

•   Solar panels do not need regular maintenance or service once installed and they last for a very long period of time, for years.

•   Kilowatt hour is the unit used for measuring solar energy.

•   Hefty investment is one reason that disallows people from using solar panels in large numbers.

Few parts of the world have already started following the trend of using solar energy including India. But, the success only lies on people’s inception.

Advantages:

Avoids greenhouse gas emission

Advantageous Facts About Solar Energy is that it dodges the harmful greenhouse gases which are caused by fossil fuels, and apart from panel production, it does not emit or emanate any kind of greenhouse gases. Solar energy is the energy got from the sun – a process devoid of any sort of harmful gases and products.

Ongoing Free Energy

Apart from the cost required for just the basic or conventional installation and maintenances, no cost is needed as the entire energy is free. There is no requirement of extensive raw materials like oil and coal, and needs basic labor only as compared to other power production houses. Raw materials are not required to be continuously extracted and neither is the need for transportation costs.

It is efficient as well as an infinite source:

According to the above mentioned facts about solar energy, we all are aware that is an infinite source of energy and that it is obtained directly from the sun it will never fade. It is a renewal energy source. Another benefit of it is that it is extremely environmental friendly and does not inflict any damage to the eco-system. It is pollution free.

Disadvantages:

•    One major disadvantage of this is that electricity generation rests entirely on how much a country is exposed to the sun. It can further be reduced due to its climatic phenomenon and conditions

•    Solar energy panel installations can lead to big expenses as well as straggle of precious time for many years and savings on energy bills to equal initial procurement.

•    The main source of solar energy is the sun; hence it can only be got during day time only. At night it cannot be extracted.

Thus with the above mentioned article all the relevant facts about solar energy, I think is quite clear to us.
