Benefits of Solar Energy

Solar energy is a type of energy derived from the sun. Since the origin of human life on earth, the sun has always been the ultimate source of energy. Every mutual process that supports ecological stability requires the presence of sunlight. In fact, all other sources of energy have been derived from the sun. So, it is basically the solar energy that manifests itself in all other sources of energy. Even fossil fuels have been formed as a result due to the heat provided by the sun, the Ocean thermal energy is also a result of the temperature difference caused by the sun rays. Even wind energy is a result of uneven heating caused by the sun.

Solar energy constitutes the non-conventional or the modern source of energy. It is a renewable resource since the sun will continue to radiate an enormous amount of energy for another five billion years. The emerging technologies have provided a new outlook on the concept and design of solar energy. A fact that remains hidden is that all solar energy devices are usually based on solar constant. If we go deep into the physics we will ultimately discover that India is privileged to receive a large amount of solar energy for a large part of the year. On average daily India receives solar energy equal to 4to 5 kWH/m2. The devices usually convert solar energy into electrical energy by using two embedded layers of Silicon. A potential difference is created when the electrons trapped between the silicon arsenic layer and the silicon boron layer are made to move upon the action of sunlight. Usually, a solar panel consists of multiple solar cells.

India has enormous potential for achieving its energy needs through solar energy. But still, solar energy remains a potential resource in Gujarat and Rajasthan, the states which receive the largest amount of solar energy.

Indeed, solar energy is the future of NON-CONVENTIONAL ENERGY. The energy is being utilized in all remote and inaccessible hamlets where the laying of power lines can be commercially viable.

But still, all other sources enjoy an unfair advantage over this resource. Actually it’s all because of limited usage. The cost of solar devices remains high. They are still very expensive for the middle class and the poor to afford. The Government of India should extend support to solar projects and should initiate a solar policy. The framework of the solar policy must be specifically designed to support maximum usage and lower costs. Actually combining innovation with solar interfaces is really very important. New plans need to be developed and implemented. There should be a rural infrastructure that supports solar energy in day to day activities.

Let's arrive at an important conclusion that in order to furnish such high energy needs of the overgrowing population, solar energy resources need to be developed and properly utilized. Solar energy is a clean source of energy. So if we develop such sources we will achieve a dual objective –one that we will be able to cater to the energy needs and secondly we will be able to tackle the evil of pollution.
