Advantages and Disadvantages of Solar Energy | pros and cons

Solar energy is a trending topic of science in recent time. The non-renewable sources of energy are about to extinct due to its limited storage on the Earth. Therefore, alternative sources of energy are needed to fulfill our daily needs of energy. There are some renewable sources of energy like Solar energy, Wind energy, Geo-thermal energy, Hydro energy, etc. available in nature which can be good options as the alternative sources of energy. In this post, I am going to share some advantages and disadvantages of Solar energy with a short description.

What is Solar Energy?

Solar Panel
Solar Panel

The term “Solar” comes from the word “Sun”. The light energy coming from the Sun is known as Solar energy. Light energy of Sun can be converted into heat energy and electric energy that can fulfill our daily requirements of energy.

How is solar energy used?

Now, what solar energy is used for? Silicon-made Solar cells can convert the Solar energy into the electric energy. This will fulfill the shortage of electricity. Apart from this, the Solar energy is a powerful source of heat energy. If the solar energy is available then we don’t need to burn coal or petroleum to produce heat.

The usage of Solar energy has some pros and cons which are discussed in later half of this post.

A short description on Solar energy

At the present time, the non-renewable sources of energy like coal, petroleum, etc. are the most dependable sources of heat and electricity. But, the world is facing the crisis of these sources of energy. Therefore, people are thinking to use the renewable sources of energy. The light energy of the Sun is the Solar energy which is a potential alternative source of energy. One can convert the Solar energy into the heat energy and electrical energy. The conversion of light energy into the heat energy is an old deal. For example: If we need some hot water, we can get it by placing a bucket of water in the Sun. But, the conversion of solar energy into the electricity is a new finding.

Albert Einstein discovered the Photoelectric effect in 1905 where he explained how light can emit electrons from the metal surface. If we arrange a proper circuit, these emitted electrons flow through the circuit to give electricity. That concept is now adopted with a proper way. We can convert the Solar energy into electricity easily. The discovery of Semiconductor materials has made it easier. Many of the official and private sector buildings use Solar panels as the source of electricity which consist of Solar cells made of photo-diodes.

Solar energy as renewable resource

The non-renewable sources of energy like Coal, Petroleum, etc. do not have unlimited storage. These are vanishing day by day as we are using these. We cannot generate these sources of energy in a quick time, it takes million of years to regenerate these sources. On the other hand, Solar energy is very much natural which can be available for the next billion of years. Sunlight will be available at every morning repeatedly when Sun comes out (except in cloudy days). This is why the Solar energy a renewable resource of energy. We can use Solar energy to heat a body, to produce electricity, etc.

There are some other renewable resources of energy like Wind energy, Geothermal energy, Hydro energy, etc.

Advantages of Solar Energy

There are some advantages and disadvantages of Solar energy and its usage. In this section, I am going to point out the advantages only. There is a separate section for disadvantages of Solar energy. The pros of Solar energy usage are as followings –

Solar energy is renewable

The main advantage of Solar energy is that it is renewable. There will not be any shortage of Solar energy as long as the Sun exists.

Impact of Solar energy on environment

The burning of Coal and Petroleum pollutes the environment badly. But, the Solar energy is natural and environment-friendly.

Low cost

Solar cells convert solar energy into electricity. Solar cells consist of Semiconductor-made photo-diodes which is very cheaper in cost. Therefore, the production cost of Solar Panels (consist of large number of solar cells) is very low.

Disadvantages of Solar Energy

There are two main disadvantages of Solar energy-

  1. It is almost impossible to get Solar energy from the Sun during the rainy season or cloudy days. Therefore, we need to have another alternative source as a back up.
  2. Solar cells cannot convert the entire amount of solar energy falling on it into the electricity. That means, the efficiency of the solar cells is not that good.

Conclusions of Solar energy

In this article, we have discussed the Solar energy, its advantages and disadvantages. We may conclude that –

  • Non-renewable sources of energy will extinct very soon. So, we need alternative energy resources.
  • Solar energy, wind energy, geo-thermal energy, hydro energy are some good resources of renewable energy.
  • Use of Solar energy is easier now. Solar cells or solar panels can convert solar energy into electric energy.
  • There are some advantages and disadvantages of Solar energy.
  • Still we are unable to use the majority part of the Solar energy due to lack of proper mechanism. So, there are many scopes of utilizing solar energy in better ways.

Hope we will be able to take full advantages of Solar energy in future. This is all from this article. If you still have any doubt on this topic you can ask me in the comment section.

Thank you!
