Introduction: Solar energy is a type of renewable energy that is extracted by the light of the sun by various modes of existing technologies like Solar cells, Photosynthesis, Photovoltaic, and solar power plants. It is an important source of energy. The two techniques that are Active Solar and Passive Solar are used for the extraction of the energy from the sunlight. Over time Solar Energy has proved to be an efficient and clean source of energy.
The interesting fact that with 1 hour of solar energy we can fulfill the electricity requirements for 1 year, but unfortunately we can use only 0.001% of solar energy using solar panels. Solar technology is constantly improving, because of which our ability to use the abundance of solar energy is increasing day by day.
According to a report by the International Energy Agency (2017), the use of solar energy has exploded and we have found the growth of solar energy to be higher than all other fuels. The day is not far off when all of us will collect electricity and enjoy solar energy.
Advantages of Solar Energy: As we know that the solar energy is renewable so it is very efficient in terms of fulfilling the needs of people in terms of energy and along with that it is environment friendly as well. Solar energy will be accessible as long as we have the existence of the sun.
Below are the major pros of solar energy:
Solar energy is pollution-free (Eco friendly) – The electricity generation from other energy sources causes lots of pollution. Solar energy is eco-friendly. We get solar energy directly from the Sun. Every day lots of sun rays fall on earth which have no use, so using them as an energy source is a productive thing.
Not dependent on other sources of energy – After the solar panel came into existence, it has reduced the pressure on other energy sources which are causing environmental issues which is a wonderful sign for both ecosystems and the environment.
No maintenance – Solar power systems do not require maintenance. Just you need to clean it regularly. But we should keep it in mind that experts who know this work well should always do cleanliness. Inverters are also a part of the system, which needs to be replaced in every 5 to 10 years i.e. Very little expenditure on maintenance and repair work besides the initial cost.
Safer than other energy source devices – Solar energy is far safer than traditional electricity sources, whether it is for use, maintenance, and repair.
Renewable energy – Solar energy is a renewable energy source. We can use it in every corner of the world, it is always available. Unlike other sources of energy, solar energy is a source of never-ending energy. So, if we use this solar energy more and more, we can save our other non-renewable energy sources.
Reduction in electricity bill – Since we generate electricity by solar energy. It will meet all our energy requirements, so it will decrease our electricity bills and save our money. Now, there are so many types of solar panels coming in which solar panels are connected with your electricity meter and during the daytime, it will save our electricity using the solar energy and at night it will use the traditional source of electricity.
Maximum Use – We use solar energy for various purposes. It can deliver electricity to areas without electricity; use it in factories, supply clean water, use in household chores, and use for space satellites. Because of this, it will gradually decrease the manufacturing cost in various industries.
Technology development – Successfully increasing the use of solar energy has led us to expect growth in industrial development and to explode. Now lots of people are using solar equipment all over the world. Because of solar energy, lots of business is developing everywhere.
Disadvantages of Solar Energy:
High Cost of Installation – The initial cost of purchasing a solar panel system can be high, it includes solar panels, inverters, batteries, wiring, and installation costs. The government is trying to reduce the price of Solar panel systems so that people understand its benefits.
A required enormous area of land – The more electricity you want to supply, the more Solar panels will be required and solar panels require considerable space to install. It will require more area, although we can put solar panels on the roofs, but the space is not enough. Now the government is using drought land and unused lands to install thousands of solar panel grids.
Weather dependent – The major issue happens when the cloudy or rainy season starts. In the rainy season duro to cloud photon energy from the sun can’t reach the surface of solar panels which causes low or zero generation of solar energy.
Storage of solar energy are expensive – Solar energy can be used immediately, or we can store it in a battery. We can use the stored energy at night, but experts say the method of collecting or storing it is expensive because we will collect the energy in the battery only when our solar system is connected to a device called the grid. After every 3-4 years, we need to change batteries connected with solar panels, so it needs some extra cash.
Conclusion: Solar energy is an excellent alternative to other energy sources, but the government needs to work more in this direction. Also, they have to spread awareness about the importance of solar energy. If we still use the traditional electricity system, in the coming generation there will be an extensive lack of all resources other than solar energy in this world.
