What is solar power? How is it generated?
Energy from the sun can be utilized in a number of ways. This utilization of radiant energy from the sun is called solar energy. Sunís rays reach the earthís atmosphere and get absorbed by the landmasses, clouds and water bodies. Sunlight is essentially a beam of electro-magnetic waves that can be captured and converted into different forms of energy. This conversion of solar energy into mechanical, chemical and electric energy is called solar power. The modern device that converts solar power into other forms of energy is called a solar power generator. 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 power generator: how does it work?
To realize the regeneration, utilization and application of sunís radiant energy, we definitely need to realize this solar power as a viable 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. Approximately seventy percent of this radiation is absorbed by the earth like the clouds, water bodies and the landmasses. The remaining thirty percent is reflected back to the space. The absorbed radiation heats the landmasses, water bodies and the atmosphere that fences the earth. 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 flux of the renewable energy on earth. Now how does a solar power generator work in a particular field economically and practically depends on how efficiently this solar radiation is being tailored by the solar power technologies at that very practical end.
Solar power generator basically works on the simple principle of capturing the sunís radiant energy and machinating it into the required form of energy according to our needs. Solar energy generators can be broadly classified into two types, namely active and passive solar power generator. Active solar power technologies make use of the sunís radiant energy directly in the concerned practical end like pumps, to convert sunlight into mechanical power, 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, On the other hand passive solar technology emphasizes 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 it is very clear now that passive solar technologies greatly deter and actually minimize the use of alternate power resources and active solar technologies favor more and more supply of solar power.
Solar power generator: Advantages and disadvantages
To understand the fact that how does a solar power generator work, we need to single out each and every pros and cons of this high end application of modern technology. The main advantage of solar power is that it is an unlimited source of energy.† Secondly, solar power is perfectly pollution free and none of the solar power technologies produces any air pollutants or greenhouse gases like the other traditional power plants. Solar power is such an amazing replacement of alternate energy resources that even cars and satellites are being run with this versatile and specialized fuel! Economically also solar power cells are pretty cost effective to be deployed for practical usage since the source itself is free and once installed properly the maintenance cost is barely minimal. However, the fact that a very strong sunlight and therefore areas with very strong and consistent sunlight are required for the solar power generators to work limits the use of this technology to only some few parts of the world. A diffused source would produce a low energy which will not be economic to the expensive set-up. Developments are happening though to overcome these limitations so that solar power technologies can be used without any dubiety by the environ-conscious citizens worldwide.
The many advantages make it logical to generate solar power at home itself by installing a system. All you need is a guide to know where to set it up in your home, how to complete the wiring and the installation procedure, where to affordably find the batteries and the parts and what are the safety precautions that have to be followed.
