Solar Power Generation
Solar energy appears to be the most promising among the non-conventional sources of energy. The sun’s great energy release is the result of an elaborate chemical process in the Sun’s core-a process of thermo-nuclear fusion like the reaction in hydrogen bomb. Sun radiates energy of about 3.5 X 1023 kw into space and only 2 X 1014 kw reaches the earth. Converting even a part of the solar energy a very very low efficiency can produce in far more energy than could conceivably be harnessed or utilized for power generation. Even if 90 per cent of the solar energy reaching the earth is lost by reflection, refraction and absorption in the outer layers of atmosphere, the quantity available at the surface is 2 X 1013 kw, which is equivalent to the burning of some 17 million tons of coal. The stupendous solar energy which is non-exhaustible and completely pollution free, could drive the civilization forever, if it could be properly and economically harnessed. However, it has got some serious draw-backs-energy density per until area is very low, it is available for only a part of the day, and cloudy and hazy atmospheric conditions largely reduce the energy received. Therefore, in harnessing solar energy for generation of electrical power large areas to collect sufficient amount of energy and the means to store it will be required. The solar energy is collected through collectors (flat plate or concentrating collectors) whose surfaces are designed for high absorptive low emissivity. The heat absorbed is utilized to evaporate some working medium or heat feed water to convert it into steam which run the turbine coupled to the generator or alternator.
