Importance of solar energy

 Importance of solar energy

53% of electricity production in the country is done by coal and it is estimated that this will also end by the year 2040-2050. More than 72% of the people of India live in villages and half of these villages are living without electricity. Now India has come to such a situation that now we have taken steps for more production of energy, in the field of conservation of energy, its renewal and protection. The use of solar energy is the best way to meet this demand, so that we can establish harmony between the demand and supply of energy.

(What is solar energy) :

In common language, solar energy refers to the energy obtained from the sun. When energy is generated by gathering the sun's rays at a point, this process is called solar energy production. Solar energy means converting the sun's rays into electricity, whether it is P. V. [ Photovoltaic ] directly by or c. S. P. Indirectly by [Concentrated Solar Power]. c. S. P. Lenses or mirrors and tracking devices are used to generate solar energy and collect a very large portion of sunlight into a small beam. Solar power plants work in the same way.

India is a tropical country, one of the benefits of which we get in the form of sunlight. Being a tropical country, we receive solar radiation throughout the year, including about 3000 hours of sunlight, which is equivalent to 5000 trillion kWh. In almost all areas of India, 4 – 7 kWh per square meter is equivalent, which is equivalent to 2300 – 3200 hours of sunlight per year. Since most of the people of India live in rural areas, there are many uses of solar energy. Also, there are possibilities of development and if the use of solar energy starts, then there will be a reduction in the use of branches and wood in domestic work. This will not cause air pollution.

In India, vast scope is available for generating solar energy because the land of India is located in such a place, where sunlight reaches in sufficient quantity. The amount of sunlight that reaches the earth's surface every year is enormous. More than twice as much sunlight reaches the earth every year as many non-renewable materials, such as coal, oil, natural gas and other uranium materials obtained by mining, are consumed in a year.

Solar energy technology -:

Solar energy is a technology developed by using solar radiation and heat from the sun. There are other forms of it, such as -: solar heat, solar radiation and artificial photosynthesis, etc.

It seems even more reasonable because of the benefits of solar energy. Some of the benefits of this are listed below:

Solar energy is a never-ending resource and it is the best replacement for non-renewable resources.

Solar energy is also beneficial for the environment. When it is used, it does not release carbon-dioxide and other harmful gases in the environment, so the environment is not polluted.

Solar energy is used for many purposes, such as - for heating, drying, cooking and in the form of electricity, etc. It is suitable to use solar energy in cars, in airplanes, in big boats, in satellites, in calculators and in other devices.

Since solar energy is a non-renewable energy resource. Therefore, in countries like India where energy production is expensive, these resources are the best alternative.

Solar energy equipment can be installed at any location. They can even be installed at home, because they are cheaper than other sources of energy.

 (Solar power disadvantages) -:

We cannot produce electricity from solar energy at night.

At the same time, even during the day when the weather is rainy or cloudy, the work of electricity generation cannot be done by solar energy. For this reason, we cannot fully rely on solar energy.

Only those areas can be able to produce solar energy, where sufficient amount of sunlight comes.

In order to generate solar energy, apart from solar devices, we need inverters and batteries for its storage. By the way, solar equipment is cheap, but the accompanying useful inverter and battery make it expensive.

Solar devices are large in size, so a large area of ​​land is needed to install them and once these devices are installed, that land is used for this purpose for a long time and it is used by someone. And it cannot be done in action.

The amount of energy generated in this way is very less compared to other resources, which are unable to meet our needs.

Solar equipment is delicate, and it is very important to take care of its maintenance, which causes additional costs in addition to the expenses on insurance etc., which increases the expenses.

In India also many projects have been started keeping in mind the benefits of solar energy -:

India's Thar Desert has launched the country's best solar energy projects so far, capable of generating an estimated 700 – 2100 GW of energy.

On March 1, 2014, the then Chief Minister of Gujarat inaugurated the country's largest solar power plant in Neemuch district of Madhya Pradesh.

The central government has set a target of generating up to 20,000 MW of energy by the year 2022 by starting the 'Jawaharlal Nehru National Solar Energy Project [JNNSM]'.

By solar energy and in it auxiliary objects and equipments are manufactured, some of which are as follows -:

solar panel,

Brainy Eco Solar Home UPS 1100,

Solar DC System 120,

Solar Power Conditioning Unit,

PV Grid Connected Inverters,

Solar Charge Controller -:

PWM technology,

MPPT Technology

solar conversion kit,

solar shine wave inverter,

solar battery,

Solar Home Lighting System -:



Solar street lighting system, etc.

Thus, solar energy has adopted a developed form in our country and we are benefiting from its benefits.
