Solar and Wind Power

Definition of solar energy and the way it is generated

Solar energy can be defined as the process of transforming naturally received sunlight into machine power, chemical power and electric currents. In other words, the process of storing and using the radiant energy of the sun is termed solar energy. Different technologies and devices related to solar energy are used to convert sunlight into mechanical and chemical power, and electricity. Chief among these devices are water pumps, solar chimneys, photovoltaic cells and solar thermal equipments. In case you are thinking how exactly solar energy works, we would be addressing precisely that issue in this article.

Solar energy working mechanism ” the method and its immense power

For learning how solar energy works, the steps of regenerating and applying solar power has to be understood in minute detail. Solar energy also needs to be one of the best sources of abundant and renewable energy. The upper layers of the earths atmosphere are hit by the electromagnetic waves of sunlight. About seventy percent of these waves are reflected back into space. Clouds, landmasses and water bodies on the earths surface help in the absorption of the remaining thirty percent. Radiant heat can be obtained from these radiations of the sun. This radiant energy can be effectively stored and converted to electricity, chemical power and mechanical power, via different machines. In fact, about 99% of the total amount of renewable energy reserves on earth, that can be put to use, is accounted for by solar power. Individual power requirements determine the efficiency with which solar energy is used by the different techniques. This in turn, decides how the solar power would be made to work. Indeed, solar energy finds usage in a wide range of common applications, including architecture, cooking and planning of urban areas. Solar power may be used to drive vehicles as well.

How the solar energy would be made to work, and what tools would be used for these purposes depend on the final use to which it will be put. However, a broad classification of solar energy technologies into two separate types is easily possible. These are: 1) active solar energy techniques and 2) Passive solar energy techniques. The former method aims at direct absorption of the radiations of the sun by pumps (for conversion to mechanical power), by photovoltaic cells (for transformation into heat) or by fans (in order to generate electricity from solar power). The latter methodology, however works differently. The passive solar techniques try to obtain as much sunlight as possible. Urban planning is eased by this technique, since constructions are done in well-lit spaces which have access to plentiful sunrays. These techniques hence aim to do away with all other sources of energy, and establishing solar energy as the ultimate source. Active solar techniques, try to maximize the amount of supply of sunlight. Such detailed analysis makes it quite clear that solar energy plays a large role in our lives, and as such it should indeed be carefully examined. The fields of application of solar power are manifold as well. Solar energy is used for cooking, agriculture, architecture, planning for cities, solar lights, disinfection, desalination, and generating electricity, as well as for other purposes too. Hence, the benefits of solar power are large. However, the few cons of using solar power as an energy source need also be considered.

Advantages and disadvantages of solar energy

The advantages as well as the disadvantages of solar energy need to be understood, in order to know how solar energy works. Firstly, solar energy is free, abundant and a renewable source. This indeed makes it am extremely advantageous source of power. In stark contrast to other conventional fossil fuel sources of energy that release harmful greenhouse gases that contribute to global warming and pollute the atmosphere, solar energy is extremely eco-friendly and does not use these gases at all. It can even be used as the source of power on which vehicles and satellites can be operated. There are, however, certain limitations on the power of solar energy sources. Firstly, these solar power plants should only be set up at places where exposure to continuous and strong sunlight is available. Hence, these plants are found only at certain select places. Secondly, a solar power plant at a place that has intermittent sunlight would never be able to produce the targeted outputs. With the high costs of installation, such plants would not remain economically viable either. However, experts are trying to deal with these problems, and we can expect that in not too distant future, almost all homes would have a solar power converter. That would indeed usher in a pollution-free, cleaner environment.

Users should ideally take help from a reference manual to learn how to install the solar power plant. Generally, information on the best place to install the system, the way to acquire other components at cheap prices and how to get the batteries free also need to be known. How the wiring is to be done as well as the necessary safety tips are also certain things you must know. Indeed, a well-documented reference manual can ease the process of setting up a solar power system.
