  • 1. Solar Energy B.Murali Krishna 08841A0467
  • 2. Rural Electrification Empowering rural INDIA B.Murali Krishna 08841A0467
  • 3. o At the rate of 48 per dayo More than 1650 per yearo At least 10,500 from 1996-2007
  • 4. Farmers who committed suicide
  • 5. Reasons• Climatic conditions• Politics• Lack of energy
  • 6. Law of conservation of energy :“Energy can neither be created nor destroyed but it can be converted from one form to another form”
  • 7. HISTORY OF ELECTRICITY • Many people think Benjamin Franklin discovered Electricity with his famous kite- flying experiments in1752 • But electricity was not discovered all at once
  • 8. THE BATTERY • In 1800, Alessandro Volta , an Italian scientist, made a great discovery. • He soaked paper in salt water, placed zinc and copper on opposite sides of the paper, and watched the chemical reaction produce an electric current.
  • 9. • Volta had created the first electric cell.• By connecting many of these cells together, Volta was able to “string a current” and create a battery.• It is in honor of Volta that we measure battery power in volts.
  • 10. A CURRENT BEGAN • An English scientist, Michael Faraday, was the first one to realize that an electric current could be produced by passing a magnet through a copper wire. • Almost all the Electricity we use today is made with magnets and coils of copper wire in giant power plants.
  • 11. Types of energy sourceso Renewableo Non renewable
  • 12. Types of non renewable energy resourceso Coalo Petrolo dieselo Natural gas
  • 13. Disfavors!!!o extinction of resourceso Increasing demando pollution
  • 14. TYPES OF RENEWABLE ENERGY SOURCESo Solar energyo Wind energyo Tidal energyo Geo thermal energyo Bio mass
  • 15. here comes the SUNSolar energy is the radiant light and heat from the sun
  • 16. The total solar energy available to earth isapproximately 3850 ZETA joules per year
  • 17. Facts about solar energy.• Earth surface receives 1.2x1017 W of power from sun.• Energy supplied by the sun in one hour is almost equal to the amount energy required by the human population in one year.• Most if the other source on renewable energy have their in sun.
  • 18. Why Solar Energy.• Solar energy is the most readily available source of energy.• It is free.• It is also the most important of the non- conventional sources of energy because it is non-polluting.
  • 19. Solar Cell (Photovoltaics) ElectricityLight Solar Cell (PV)
  • 20. The PV Value Chain (multi-crystalline) Polysilicon Wafer Solar Cell Solar Module SystemsChemical Process Casting Surface Treatment Assembly Installation (purification) Cutting Operation
  • 21. Developments in solar cells First generation – pure silicon,33%efficiency, more expensiveSecond generation -- thin film solar cells low cost low efficiency, CdTe , selenium , amorphous silicon Third generation– low cost high efficiency multi junction, tandem cells nano structured
  • 22. SUNENERGYMENALTERNATIVES
  • 23. SOLAR ENERGYSolar energyis the energygained bycapturinglight and heatemitted bythe Sun. Solar panel
  • 24. Solar Energy It is called renewable energy to the It is a so-called renewable energy obtained from natural sources energies, particularly clean inexhaustible. group, known as clean energy or green energy. The sunflower is the icon of renewable energy by harnessing its great sunlight and its "similar" to the Sun
  • 25. TYPES OF SOLAR ENERGY•Passive SolarEnergy: Harnessthe suns heatwithoutmechanisms ormechanicalsystems.
  • 26. TYPES OF SOLAR ENERGY•Solar ThermalEnergy: To producelow-temperature hotwater for sanitaryand heating.
  • 27. TYPES OF SOLAR ENERGY•SolarThermoelectricEnergy: To produceelectricity with aconventionalthermodynamiccycle from a hightemperature heatedfluid (thermal oil).
  • 28. TYPES OF SOLAR ENERGY•Solar Hybrid Energy:combines solar energywith other energy.According to theenergy with which is ahybrid combining:-Renewable: Biomass,wind power.-Fossil.
  • 29. TYPES OF SOLAR ENERGY•Solar Wind Energy:Works with the air heatedby the sun, which risesthrough a chimney whereare the generators. Wind generator / solar laptop
  • 30. TYPES OF SOLAR ENERGY•Photovoltaic Solar Energy:Its a way of obtainingelectricity throughphotovoltaic panels. Photovoltaic solar panel
  • 31. Current growth in theSolar photovoltaicis limited in2006 for lack of subjectpremium (so-grade siliconlar) in the market.
  • 32. The burning of rice husk is obtained18% of ash containing 92 percentsilicon.
  • 33. Photovoltaic cells convert the sunsradiation directly into electricity,using the conductive properties ofsilicon.
  • 34. PHOTOVOLTAIC MODULES A photovoltaic module generates electricity that can be used directly or stored in batteries for later use.
  • 35. Spain is currently one of the world producers of photovoltaics with aninstalled capacity of 3,200 MW estimated, behind Germany, which has3,800 MW.
  • 36. OUTLINE OF THE FABRICATION OF A SOLAR PANEL
  • 37. The first photovoltaic solar panel arrived in Spain was in the year 1978 and is manufacturedin the U.S., after three decades and is in perfect condition.
  • 38. HY-BIRD: First airplane that will go around the world using only renewableenergies, hydrogen-powered and photovoltaic solar energy. Solar cells arelocated in the wings.
  • 39. Satellites with photovoltaic panels to sendenergy from space to Earth. NASA andJapan already studying install 1 km2 ofsolar panels in orbit in a year that willproduce more energy than all the knownoil reserves.
  • 40. At the end of thelifetime of solarpanels, can be adifficult pollutantrecyclable wastetoday.
  • 41. We must seizeenergy from the sun bycapturing light andheat issues.
  • 42. Street Light MNES Traffic SignalGarden Lights Blinker
  • 43. 10 kW roof integrated photovoltaics at CSE canteen, Delhi
  • 44. Indian Oil Corporation Building, Delhi (14 kW BiPV and 4000 lpd SWHS)
  • 45. Main Application Areas – Off-grid Space Water Telecom Pumping Solar Home Systems
  • 46. Challenges……..o High capitalo Land scarcityo Slow progresso Climatic conditions
  • 47. Applications …o domestic lightingo street lightingo village electrificationo water pumpingo Solar satelliteso powering of remote telecommunication repeater stations ando railway signals.o Solar vehicles
