  2. 2. TOPICS  What is solar energy?  Why solar energy?  Main uses of solar energy  Introduction of Solar power plant  Types of solar power plant  Photovoltaic solar power plant  Concentrated solar power plant  Conclusion  References 2
  3. 3. WHAT IS SOLAR ENERGY?  The most precise Solar Energy definition : Energy from the sun.  But what is solar energy really? There are two types of solar energy: Thermal Energy & Electric Energy.  Thermal Energy: Thermal Energy is everywhere. It heats the earth, our bodies and our homes. It dries our clothes . All for free!  Electric Energy: Electric Energy uses the power of the sun to produce electricity through solar cells, otherwise known as Photovoltaics (PV). 3
  4. 4. • World Energy Conservation predicted estimation about the rate of utilization of energy resources shows that the coal deposits will deplete within the next 200 to 300 years and petroleum deposits will deplete in next few decades. • The most advantage using Solar Energy is that this is distributed over a wide geographical area, ensuring that developing regions such as India have access to electricity generation at a stable cost for the long-term future. 4 WHY SOLAR ENERGY?
  5. 5. MAIN USES OF SOLAR ENERGY  The main uses of solar energy are: 1. In solar power plants 2. In water treatment 3. In water heating 4. In cooking 5
  6. 6. SOLAR POWER PLANT  Solar power plant is based on the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP).  Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam.  Photovoltaics converts light into electric current using the photoelectric effect. 6
  7. 7. TYPES OF SOLAR POWER PLANT  There are mainly two types of solar power plants:  1. Photovoltaic solar energy plant  2. Concentrating power plant 7
  8. 8. PHOTOVOLTAIC POWER STATION  A photovoltaic power station, also known as a solar park, is a large-scale photovoltaic system (PV system) designed for the supply of merchant power into the electricity grid.  Photovoltaic cells will capture the energy which is generated from the sun and converted into electricity.  They are sometimes also referred to as solar farms, especially when sited in agricultural areas. 8

  11. 11. CONSTRUCTION AND WORKING Solar array arrangements:  The solar arrays are the subsystems which convert incoming light into electrical energy.  They comprise a multitude of solar modules, mounted on support structures and interconnected to deliver a power output to electronic power conditioning subsystems.  They are mainly of three type: 1. Fixed arrays 2. Dual axis trackers 3. Single axis trackers 11
  12. 12. CONSTRUCTION AND WORKING Power conversion:  Solar panels produce direct current (DC) electricity, so solar parks need conversion equipment to convert this to alternating current (AC), which is the form transmitted by the electricity grid.  This conversion is done by inverters. Transformers:  The system inverters typically provide power output at voltages of the order of 480 VAC. Electricity grids operate at much higher voltages of the order of tens or hundreds of thousands of volts, so transformers are incorporated to deliver the required output to the grid. 12
  13. 13. CONCENTRATED SOLAR PLANT  The method of functioning of these solar power plants is similar to that of the photovoltaic solar energy plants.  The extra addition in these concentrating power plants is that they make use of mirrors and lenses in order to capture energy from the rays of the sun.  The light from the sun will be directed towards the photovoltaic cells and they will be converted into heat energy. 13
  14. 14. CONCENTRATED SOLAR PLANT  Concentrated solar power (also called concentrating solar power, concentrated solar thermal, and CSP) systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a small area.  Electricity is generated when the concentrated light is converted to heat, which drives a heat engine (usually a steam turbine) connected to an electrical power generator or powers a thermochemical reaction (experimental as of 2013). 14

  18. 18. CONCENTRATED SOLAR PLANT  Concentrated-solar technology systems use mirrors or lenses with tracking systems to focus a large area of sunlight onto a small area.  The concentrated light is then used as a heat.  Mirrors focus sunlight onto a glass receiver containing water that can be heated.  Water passes to heat exchanger for additional heating using natural gas to make high pressure steam.  Steam is fed to turbine which generates electricity.  Electricity is transfer from storage substation. 18
  19. 19. TECHNIQUE USED TO CONCENTRATE SOLAR ENERGY IN SOLAR PLANT 1. Parabolic trough:  A parabolic trough consists of a linear parabolic reflector that concentrates light onto a receiver positioned along the reflector's focal line.  The receiver is a tube positioned directly above the middle of the parabolic mirror and filled with a working fluid. 19
  20. 20. TECHNIQUE USED TO CONCENTRATE SOLAR ENERGY IN SOLAR PLANT  2. Solar power tower: A solar power tower uses an array of tracking reflectors (heliostats) to concentrate light on a central receiver atop a tower . These are more cost effective, offer higher efficiency and better energy storage capability among CSP technologies. 20
  21. 21. TECHNIQUE USED TO CONCENTRATE SOLAR ENERGY IN SOLAR PLANT 3. Dish Stirling:  The Stirling concentrating dish solar dish combines a parabolic with a Stirling engine which normally drives an electric generator.  The advantages of Stirling solar over pv cells are higher efficiency of converting sunlight into electricity & longer lifetime. 21

  23. 23. CONCLUSION  Solar energy is a resource that is not only sustainable for energy consumption, it is indefinitely renewable. Solar power can be used to generate electricity, it is also used in relatively simple technology to heat water. The use of skylights in construction can also greatly reduce energy expenditure required to light rooms in homes interior during day. 23
