Solar Energy: Installation and Economic Benefit of Photovoltaic Systems [Student’s name] [Course] [University] [Professor’s name] [Due date] Introduction Solar energy has been the most dominant energy source since the dawn of civilization, though indirectly.
(Daniels 1971: 490) Meanwhile in 1973 another researcher, George O.G. Lof said that the man has to find other energy sources as the use of fossil fuel is unsustainable. For him, the development of technology that captures solar power is much more important. He expounds: The raw energy, in the form of electromagnetic radiation, reaches the earth’s atmosphere at a rate of 170 trillion kilowatts. Even after about one-fourth is scattered into space by clouds and dust, the quantity of energy reaching the land area of the United States is more than 700 times the current demand for all types of energy. (Lof 1973:53) For Lof, fossil fuels have to be replaced with renewable sources of energy because its inventory is finite and will soon run out. Moreover, as supply of petrol fuels decrease, its cost will increase steeply. More than 40 years after Lof’’s pronouncements, the world is now experiencing the repercussions of the indiscriminate use of petrol fuels. For one, price of petrol fuels are at record high levels. ...
