Solar Energy by Karansank
‘Solar Energy is a safe solution for our energy crisis and is environmental friendly’ may be a pleasant music for the ears. But in reality, it is otherwise, mainly due to the that commercial generation of solar energy needs vast area of lands apart from water for the periodical cleaning up of parabolic mirrors. As on date, there are two types for the generation of solar energy. 1.Photovoltaic panels. 2.Concentrated Solar Power (CSP) The first one is used for a limited power generation of heating water for bath, lighting a few streets or houses. Its power is user specific and cannot be useful during winter and rainy days. Cells in the Photovoltaic panels convert sunlight directly into electricity and these panels sit mainly on roofs and need little land. These are individual focus and could not be extended for mass generation of electrical energy. The second one contains parabolic mirrors, shaped as ultra long troughs, which concentrate sunlight into a long tube of molten salts that
