From the very beginning of the mankind, power generation and using it efficiently has been one of the most burning issues. For the past thousands of years, various sources of energy have been used for power generation. But alongside them a new form of energy is being popular day by day. It is the solar power. It is pollution free, noise free in some cases and above all the most favoured renewable energy of the present time.
Electricity is the most used form of energy because it is possible to convert electricity into another form of energy more efficiently and effortlessly. Solar panel which is used to make the said conversion, that’s why is being popular overnight. No other forms of energy are as abundant as the solar power. It can be placed on roof tops, on the upper surfaces of the vehicles like trains (DEMU) and even in the handheld devices. In a word, solar power is compatible with almost every device from small scale to large scale.
Basically, the power generation technology in solar panel follows the photovoltaic effect. When the sunlight beams the surface of the panel, silicon microchips are forced to emit electrons by the light energy. These yields direct currents. To convert it into practical AC of desired frequency and amplitude, converter is used herewith. Several numbers of solar panel modules are sometimes combined and then an inverter. Without solar lights’ energy, this panel doesn’t work. And it is the positive side. Because sun light is eternal, there is no chance of exhausting this source in near future, not even in 500 million years. It is not wonder that the sun’s beam fallen on the earth in one hour is more than the total annual energy consumption. So several researches are being carried out to improve solar panel: the key to conversion. System loss is being reduced. The world leaders and the leading scientists are interested on this point.
The advantages of solar energy are too many to describe. First of all it is pollution free. No other energy sources except wind mill offer us to produce energy, specifically electrical energy without a big sound. The sun is the only source of all kinds of energy on the earth, and so solar energy is reliable. It is called the green technology because it is carbon emission free. Solar based power plants helps to reduce the demand of fossil fuel, where that is the only medium of power. It also assures the proper utilization of abundant lands. Solar energy is clean and conversion is waste free. Sun light can be temporarily exhausted for bad weather, but is sure to get it in a fair one.
The earth is losing fuel source. Sources like coal, gasoline are on the decrease. Uranium can also be exhaust in a late future. Only solar and air energies are left. Windmill is not congenial for all the places. So it is the high time to make solar power a major source of energy of today’s world. Because the future is here. Solar power will not only meet the demand of the energy, but also make the world greener, cooler and nicer one. Above all everyone will lead a life with the certainty of using adequate energy for him/her self.
