  1. 1. Solar Energy By: Sayef Amin ID No: 2013020301030 26 th Batch, Section: A
  2. 2.       Solar Energy Definition: radiant light and heat from the sun that is used and transformed into different types of energy. Most abundant source of renewable energy on the planet Production of solar energy uses heat engines and photovoltaic The most common way of collecting solar energy is by use of solar panels energy storage methods:  paraffin wax  glaubers salt salts are good  low cost  high specific heat levels and  can deliver the right temperature heat to conventional heating systems
  3. 3. Advantages/ Disadvantages   Advantages  Long lasting  Can be used anywhere  Silent and non polluting  Solar cells can be added when there is demand for more energy  Sunlight that reaches the earth everyday is 200,000 times the total electrical energy generated everyday  Solar power production is growing rapidly  It is a secure type of energy Disadvantages     High initial cost Takes a lot of solar panels to be efficient initially Can only generate during the day Cost about twice of what fossil fuels do
  4. 4. Facts about Solar Power  passive or active solar: Active; photovoltaic panels and solar thermal collectors  Passive; buildings pointed to the sun, spaces within buildings with rooms that circulate air, and building with materials that have a favorable thermal mass Solar wind and biomass are the top consumed type of energies from humans Biomass could lead solar in terms of consumption, but it is a cause of global warming and is bad for agriculture    
  5. 5. Applications:  Houses:  solar lighting, heating and ventilation systems         pumps fans and windows Use natural solar lighting when building Hybrid solar lighting: faces mirrors track the sun throughout the day and use optical fibers to distribute it Water heating: china and Cyprus have the most amount of solar thermal water heaters Farming:  greenhouses turn solar energy to hear Photovoltaic cells: collect photons and release electrons as energy Made of silicon  as small as a calculator and as large as pods in desert parabolic discs
  6. 6. Solar Energy in Daily Life     Water heating system (Schematic diagram ) Basic Theory: Collect the solar radiation, transfer it to heat energy and apply in our daily life. As the solar panel collect the heat from the solar and transfer it to the water inside the pipe, the water is heated and outflow from the other pipe. Then, we may use the hot water in the showers, warming machine.
  7. 7. Solar Energy for Industrial Applications  Basic Theory of Solar power plant    (1). Sunlight → Heat → Electricity: transfer the heat from the solar thermal collector to working medium steam, then the steam gas turbine engine drive the electric generator to generate electricity. (2) Sunlight → Electricity: Due to the photovoltaic effect, we may trans the light to electric energy directly. The Electricity may be used for microwave, TV, radio, telemetry, radio telephones and industrial production.
