Solar energy

  1. 1. Solar energyPrienai ‘Žiburys’ gymnasium
  2. 2. What is solar power? Solar power is energy from the sun and without its presence all life on the Earth would end. Solar power is produced by collecting sunlight and converting it into electricity. According to scientists, it is the most powerful energy source on the Earth. European Renewable Energy Council (EREC) predicts that by 2040 the worlds largest share - 27.4 percent of all electricity will be generated by solar power. They predict that even after 30 years, 82 percent of all electricity will be produced from various renewable sources, mainly solar and wind.
  3. 3. Electricity generationThere are two ways to use solar energy to generate electricity: Photovoltaic technology (PV) Concentrating solar thermal technology (CST)
  4. 4. Photovoltaic technology PV converts sunlight directly into electricity. The sun illuminatesthe solar cells, which convert the energy from the sunlight intoelectricity. The electricity goes into an inverter and into the powerlines to your home. However, solar panels are only effectiveduring daylight hours because storing electricity is not aparticularly efficient process
  5. 5. Photovoltaic power plants82 MW Senftenberg Solar park, Germany 80 MW Solar park Finsterwalde I,II,III, Germany
  6. 6. Photovoltaic power plants70 MW Rovigo PV power plant, Italy 84 MW Montalto di Castro PV power plant, Italy
  7. 7. Photovoltaic power plantsSolar park Gabardan in France (44 MW) Solar farm Les Mées in France (31MW)
  8. 8. Advantages of using solar power Energy is free Energy is independent. Solar batteries equipment lets us become independent from General Electric Networks and save money. Energy is ecological. Solar batteries don’t pollute environment because their materials are clear and recycled easily. Energy is longevous (long term used). Solar cells can be installed in all the objects that use electricity.
  9. 9. Disadvantages of using solar power  A large number of panels may be necessary to produce sufficient amounts of heat or electricity, requiring a significant financial investment.  Parts of the world that dont receive large amounts of sunlight are not well-suited to the generation of this type of power.  Solar panels cannot be used to generate power at night and the production of power may be impaired when there is significant cloud cover.
  10. 10. Use of solar power Measuring Stations  TV and radio transmitters and amplifiers
  11. 11. Use of solar powerControl devices  RailwayTraffic
  12. 12. Use of solar power Telemetry  Calculators
  13. 13. Use of solar power Satellite, space  Bicycles stations
  14. 14. Use of solar power Power stations  Buildings, their heating, light and constructions.
  15. 15. Solar power innovations. Solar cars Solar cars produce energy from the sun converting it into electricity. That electricity fills the battery that runs the cars motor. Instead of using a battery, some solar cars direct the power straight to an electric motor. Solar cars can get this energy through photovoltaic cells (PVC).
  16. 16. Lunokhod  Solar panels are used in creation of lunokhods. Usually high-efficiency photovoltaic (PV) cells are located on top of the lunokhods, they charge the batteries so that lunokhods can move.
  17. 17. Space stations Double-sided solar, or photovoltaic arrays, provide electrical power for the space stations. These bifacial cells are more efficient and operate at a lower temperature than single-sided cells commonly used on Earth, by collecting sunlight on one side and light reflected off the Earth on the other.
  18. 18. Solar powered containers and backpacks  Solar powered containers handle garbage more efficiently by periodically compacting the trash inside, creating space for more garbage.  A solar powered backpack is a green gadget. The photovoltaic panels in a solar powered backpack collect energy from the sun to power a variety of electronic devices, including laptops, cell phones and music players.
  19. 19. Solar windows The window lets in less light, while still being transparent, so buildings get needed shade during hot sunny hours, reducing their air conditioning use and making the building more energy-efficient. At the same time, the panels produce solar power, which the building can use for electricity.
  20. 20. Solar powered gadgets The companies Apple and Samsung are already planning to offer gadgets that are charged by solar energy. Engineers created solar powered yacht Turanor fitted with 536 square meters of photovoltaic panels, which has successfully sailed halfway around the world. In Switzerland was created first solar-powered glider (airplane) „Solar Impulse“.
