Uses of Solar Energy

We all know that solar energy is one of the most powerful and inexhaustible sources of energy. The need to explore alternative sources of energy arose when large scale consumption of energy started taking place in the form of fossil fuels, coals, gas, etc. These are forms of exhaustible energy as they are limited in supply and will end some day. Solar energy or in layman's language, the energy derived from sun rays can not only be replenished but it will never get exhausted. After considerable research and analysis, scientists started utilizing solar energy for various purposes. We shall study the common uses of solar energy in a broader sense from the following content.How does Solar Energy Work
Before going into the usefulness of solar energy, we shall study how this system works. Solar energy or the radiant energy is harnessed by human beings to serve a plentiful purposes. This energy is put forth to use by techniques that utilize various theories of physics and chemistry. The crude form of energy gets converted to useful source by the photovoltaic cells or heat engines. The energy captured by the solar cells (mostly made up of silicon) is converted to electrical energy that is useful for many purposes. The mechanism by which the solar cells work is a physicochemical process that helps in production of energy. Now this energy is harnessed to carry out a wide range of day to day works.
Solar Energy Uses
The concept of utilizing solar power has large industrial applications. If you consider solar energy over exhaustible sources of energy, then the advantages are many. Solar energy is cost effective and it requires no additional expenses in harnessing. The only cost incurred is in manufacturing the cells. The biggest advantage is that solar energy is an infinite source and we would never run short of in near future. Unlike other sources of energy (carbon dioxide and coal), solar energy doesn't cause pollution. Thus, it is completely environment friendly. It is due to these facts that future uses of solar energy are on the positive side. Let's find out the uses of solar energy from the content below.
* Micro hydro system is a mechanism by which photovoltaic (PV) cells are used for running turbines to generate hydro power. PV systems are largely incorporated in remote areas for distribution of drinking water. The use of solar pumps is very common in such areas. Hospital and water supply zones are also equipped with PV systems for carrying out desalination. The only thing that they need to do is to keep battery storage to prevent running out of supply.
* Solar energy being the cheapest source of energy is also used in small scale industries for running low duty machines. If it's used for heavy duty electrical loads then a hybrid power system is set up that serves to connect the photovoltaic cells to diesel generators. It is also used in radio stations and T.V signaling stations to garner power for generating electricity. Solar energy finds a large application in the power light houses and in aircraft warning lights. Being considerably cheap, it's also used for lighting traffic signals, buoys and offshore navigation purposes. These are some of the direct uses of solar energy.
* Photovoltaic mechanism is employed for making solar cookers and home heating appliances. The advantage of solar energy is best employed for this purpose. Solar panels are raised on roof tops for harnessing solar energy. Some other home appliances that run on solar energy are solar cookers, solar water heaters, solar refrigerators and solar composting toilets. You can check out the utility of these products from home improvement shops marketing solar energy products.
