Various Solar energy ApplicationsImportant Facts

Sun as the source of energyThe sun has a surface temperature of 6000C, maintained by continuous nuclear fusion reactions between hydrogen atoms within its interior. These nuclear reactions will gradually convert all of the hydrogen into heavier elements, but this is a relatively slow process and the sun should continue to supply power for another 5 billion years.

Important factsThe sun radiates huge quantities of energy into the surrounding space, and the tiny fraction intercepted by the Earth's atmosphere, 150 million km away, is however equivalent to about 15,000 times humanity's present rate of use of fossil and nuclear fuels. Even though approximately one-third of the intercepted energy is reflected away by the atmosphere before reaching the earth's surface, this still means that a continuous and virtually inexhaustible flow of power amounting to 10,000 times our current rate of consumption of conventional fuels is available in principle to human civilization.

5.Design of Parabolic troughParabolic GeometryA parabola is the locus of a point that moves so that its distances from a fixed line and a fixed point are equal. The equation of a parabola is as follow. X.X = 4a Y where, 4a = lattice rectum a = Focus pointBasic Parts And structureReflecting SurfaceAbsorberSupport StructureTracking SystemPumping System

K is an incidence angle modifier that can be used to account for deviations from the normal of the angle of incidence of the radiation on the aperture.

Performance and Efficiency Calculations. PERFORMANCE b. Thermal performance The actual useful energy gain: Where Aa is the unshaded area of the concentrator aperture and Ar is the area of the receiver, S is the absorbed solar radiation per unit of aperture area, Ti and Ta are inlet fluid temperature and ambient temperature FR is the collector heat removal. OVER ALL EFFICIENCY Over all efficiency of a solar collector is based on the optical and thermal performances. the over all efficiency can be calculated as; = (Qu / Ib) 100

Why Is the Sun So Important? 1. a. What is the sun? The sun is a star that is the source of light and heat for the planets in our solar system. b. What are some reasons that the earth needs the sun? Life on earth would not exist without the heat and light provided by the sun. The suns gravity also helps keep the earth in its orbit, causes weather phenomena, and plays a role in ocean tides. 2. Important facts: In terms of energy generated, burning all the coal, oil, gas, and wood on earth would only equal a few days of energy output by the sun. The total amount of energy humans have derived from burning fossil fuels since the start of civilization is less than all the energy provided by the sun in just 30 days. More energy from the sun falls on the earth in one hour than everyone on earth uses in one year. Renewable energy could account for almost 80% of the world's energy supply within four decades, but only if governments, businesses, and individuals pursue the policies needed to promote it.
