What is Solar Energy ? What is this ? And what is its use?
what is solar energy and its importance ?Actually solar energy is obtained by the rays of the sun. We know that the sun is a powerful source of energy and by installing solar energy, it can be put to good use.
What is Solar Energy?
Solar energy means that we convert the energy received from the sun into electricity and use it in our homes and business. Solar energy, radiation from the sun capable of generating heat, causing chemical reactions, or generating electricity. The total amount of solar energy incident on Earth far exceeds the current and anticipated energy needs of the world. If used appropriately, this highly diffused source has the potential to meet all future energy needs. Solar energy has become a main topic in today’s era of renewables. Do you know this interesting fact that with 1 hour of solar energy we can meet the requirements of 1 year, but unfortunately we are able to use only 0.001% of this energy. Solar energy is expected to become increasingly attractive as a renewable energy source in the 21st century because of its inexhaustible supply and its non-polluting character, in contrast to the limited fossil fuels coal, petroleum and natural gas.
As solar technology is constantly improving, so is our ability to harness the abundance of the Sun’s energy. According to a report by the International Energy Agency (2017), the use of solar energy has increased rapidly and the growth of solar energy is found to be more than all other fuels. The day is not far when all of us unitedly will be able to take advantage of solar energy generated electricity and other benefits. The Sun is an extremely powerful energy source, and sunlight is by far the largest source of energy received by the Earth, but its intensity at the Earth’s surface is actually quite low. This is essentially due to the enormous radial spread of radiation from the distant Sun. A relatively minor additional loss is caused by Earth’s atmosphere and clouds, which absorb or scatter up to 54 percent of the incoming sunlight. NS The sunlight that reaches the ground consists of about 50 percent visible light, 45 percent infrared radiation, and small amounts of ultraviolet and other forms of electromagnetic radiation.
Solar Panel / Thermal Energy what is solar energy and its importance
Flat-plate collectors are among the most common devices used to capture solar energy and convert it into thermal energy, which are used for solar heating applications. Since the intensity of solar radiation at the Earth’s surface is so low, the area of these collectors must be large. For example, even in the sunny parts of the world’s temperate regions, a collector must have a surface area of about 40 square meters (430 sq ft) to collect enough energy to meet a person’s energy needs. Solar cells are made of silicon and the cells together form solar energy (solar energy). When photons hit a solar cell, they loose electrons from their atoms. An electrical circuit is formed when the positive and negative sides of a conductor cell are connected and electricity is generated when electrons flow through such a circuit. One of the most widely used flat-plate collectors is a black It is a colored metal plate, covered with one or two sheets of glass, which is heated by sunlight falling on it. This heat is then transferred to air or water, called the carrier fluid, which flows past the plate. solar energy in india
The heat can be used directly, or it can be transferred to another medium for storage. Flat-plate collectors are commonly used for solar water heaters and home heating. Storage of heat for use at night or on cloudy days is usually accomplished by using insulated tanks to store hot water during periods of sunshine. Such a system could supply a home with hot water drawn from a storage tank, or, with hot water flowing through tubes in the floor and ceiling, it could provide space heating. Flat-plate collectors typically heat the carrier fluid to a temperature of 66 to 93 °C (150 to 200 °F). The efficiency of such collectors (that is, the ratio of the energy received to the usable energy they convert) ranges from 20 to 80 percent, depending on the design of the collector.future of solar energy in india
Concentrated solar power plants employ concentrating, or concentrating, collectors to focus the sunlight received from a wide area onto a small black receiver, which increases the intensity of the light significantly to generate higher temperatures. . Carefully aligned mirrors or arrays of lenses can focus enough sunlight to heat a target to a temperature of 2,000 °C (3,600 °F) or higher. This heat can be used to operate the boiler, which in turn generates steam for the steam turbine electric generator power plant. For direct steam production, movable mirrors can be arranged so that large amounts of solar radiation are focused onto the black pipes through which the water is circulated and thus heated.

Benefits f solar energy
- Solar power systems do not require much maintenance. Cleaning is needed only twice a year, but it should be kept in mind that always get the cleaning done by experts who know this work well.
- Solar energy is used for many purposes, such as – for heating, drying, cooking food and in the form of electricity, etc. The use of solar energy is suitable for use in cars, in airplanes, in big boats, in satellites, in calculators and also in other devices.
- Some pollution is bound to happen during the generation of electricity or other energy source and this pollution harms the environment. On the other hand, there is no such difficulty in the generation of solar energy.
- Solar power equipment can be installed at any place. It can even be installed at home, as it is also cheaper as compared to other sources of energy.
- Solar energy is a never ending resource and it is the best replacement of non-renewable resources.
- After the advent of solar energy and its increasing use, the pressure on other energy sources has reduced, which is a good sign for both the ecosystem and the environment.
- Since solar energy is a non-renewable energy resource. Therefore, in countries like India, where the production of energy is expensive, then these resources are the best option there.
- Solar energy is also beneficial for the environment. When it is used, it does not release carbon-di-oxide and other harmful gases into the atmosphere, so the environment is not polluted.
- Inverters are also a part of the system, which needs to be replaced every five to 10 years, meaning that apart from the initial cost, there is very little cost on maintenance and repair work.
- Solar energy is much safer than conventional sources of electricity, whether in terms of usage or maintenance and repair.
Disadvantages of Solar Energy
- The initial cost of purchasing a solar system can be quite high, including the cost of solar panels, inverters, batteries, wiring and installation.
- In order to generate solar energy, apart from solar equipment, we need inverter and battery for its storage. Although solar equipment is cheap, the useful inverter and battery together make it costly.
- Solar devices are large in size, so large area of land is required to install them and once these devices are installed, then that area is used for this purpose for a long time and it can be used for any purpose. And can’t be done in work.
- The amount of energy generated in this way is very less in comparison to other resources, which are unable to meet our needs.
- The more power you want to supply, the more solar panels will be needed and the solar panels require considerable space to be installed. That is, more area will be required for this, although solar panels can be installed on the roofs, but the space is not enough. Alternatives to this problem are also being sought.
- We cannot do the work of generating electricity from solar energy at night.
- Also, even during the day when it is rainy season or cloudy, then the work of generating electricity cannot be done by solar energy. For this reason we cannot fully rely on solar energy.
- Only those areas can be capable of producing solar energy, where there is sufficient amount of sunlight.
- Solar equipments are delicate, whose maintenance is very important to take care of, due to which there are additional costs due to the expenditure on their insurance etc., which increases the expenses.
What will be the future of solar energy – what is solar energy and its importance?
All these changes will increase the employment of people in the solar industry. From today itself, people have started working in Solar by becoming Dealers, Distributors and Influencers.
