Solar Energy Systems-Is It Worth It?

What is solar energy? What are the solar energy systems?

Solar energy system is all about utilizing the radiant energy emitted by the sun in the form of sun rays that are essentially electro magnetic waves. Sunlight is actually a beam of electromagnetic waves that are absorbed by the upper layers of earthís atmosphere. This is called solar radiation and the energy is called radiant energy. A good amount of this absorbed sunlight can be captured and machinated into different forms of power suiting our various requirements. This conversion of this radiant energy into electricity, mechanical power or even chemical power is called as solar energy. The modern devices that convert solar power into other forms of energy are called solar energy systems. There are different types of solar power generators like the photovoltaic cells, solar thermals, solar heaters etc. In this article we will be throwing some light on the types and functions of solar power generators.

Solar energy systems: how effectively do they work?

Solar energy systems work on the simple principle of trapping the sunís radiant energy and devising it into the needed form of energy according to our needs. Solar energy systems can be broadly classified into two types, namely active and passive solar power generators. Active solar energy technologies make use of the sunís radiant energy directly in the concerned practical end like pumps, to convert sunlight into mechanical energy, photovoltaic cells to convert sunlight into heat, and even fans to convert solar energy into electrical power. Other examples of active solar technology are solar thermals, solar heaters, solar vehicles, etc. And passive solar technology stresses on the direct use of sunlight like designing buildings with well-lit and well-circulated spaces, citing a building optimally to the sun etc. Thus now it is very clear that passive solar energy technologies greatly deter and actually downplay the use of alternative power resources and active solar energy systems favor more and more supply of solar power.

To empathize the utilization, regeneration and application of sunís radiant energy, we definitely need to realize this solar power as a feasible resource. As stated above let us discuss in detail as to what at all this solar energy is and how it can be regenerated into desirable and applicable forms of power. The sunís rays are made up of electromagnetic waves that hit the earthís upper atmosphere. About seventy percent of this radiation is absorbed by the earth like the clouds, water bodies and the landmasses. The remaining thirty percent gets reflected back to the space. The landmasses, water bodies and the atmosphere that fences the earth are all heated up by the absorbed radiation. This is called radiative heating of the earthís atmosphere. And the radiation produced due to direct sunlight causes solar radiation and the heat produced is called radiant heat. This solar radiation accounts for about 99 percent of the usable flow of the renewable energy on earth. Now how does a solar energy generator work effectively in a particular field economically and practically depends on how expeditiously this solar radiation is being oriented by the solar energy technologies at that very practical end.

Solar energy systems: advantages and disadvantages

To realize the fact that how do the solar energy systems work, we need to single out each and every pros and cons of this high end application of modern technology. The biggest advantage of solar power is that it is an absolutely limitless source of energy.Secondly, solar energy is perfectly free of any air pollutants and none of the solar power technologies produces any air pollutants or greenhouse gases like the other conventional power plants. Solar power is such an amazing replacement of alternate energy resources that even cars and satellites are being drawn with this versatile and specialized fuel! Economically also solar energy cells are very much cost effective to be deployed for practical usage since the source itself is free and once installed properly the maintenance cost is barely minimum. However, the fact that a very strong sunlight and therefore areas with very strong and consistent sunlight are needed for the solar energy generators to work, limits the use of this technology to only some elite parts of the world. A diffused source would produce a low solar energy which will not be economical to the pricey set-up. Developments are happening though to overcome these limitations so that solar power technologies can be used without any uncertainty by the environ-conscious citizens worldwide.

Solar power is a superb alternative because as previously mentioned, the advantages are both financial as well as ecological. Thus setting up a system at home makes a lot of sense. And the best news is you can do it yourself provided you have some knowledge of where best it will work, how to install the home solar power system, getting the parts cheaply, procuring the batteries free, wiring the system and the safety precautions. With this knowledge, you can install the solar power system efficiently and safely in no time and make it up and running.
