Solar Final

  1. 1. European Energies Solar energy group PORTUGAL, FEBRUARY 2010
  2. 2. World Energetic Consumption 79,5% of the energy used by humans came from fossil fuels in 2000 Source: Internacional Energy Agency
  3. 3. Concepts •Solar energy is the energy derived from the sun through the form of solar radiation. •Solar powered electrical generation relies on photovoltaics and heat energies.
  4. 4. TYPES OF SOLAR PANELS Monocrystalline Solar Polycrystalline Solar Panels: Panels: - Made from a large crystal - The most common, less of silicon expensive - Most efficient, more - it consists of multiple expensive amounts of smaller silicon crystals
  5. 5. SOLAR TECHNOLOGIES ACTIVE SOLAR PASSIVE SOLAR – use photovoltaic - Include selecting panels, pumps & materials with thermal solar thermal properties, designing collectors spaces and buildings - purpose: converting - purpose: reducing sunlight into energy the need for & increasing the alternative resources supply – supply - demand technologies technologies
  6. 6. APPLICATIONS OF SOLAR TECHNOLOGY Architecture and urban • Passive solar architecture oriented planning relative to the sun Agriculture and • greenhouses horticulture • Daylighting systems Solar lighting • Hybrid solar lighting • Water heating Solar thermal • Heating, cooling, ventilation • Photovoltaics (PV) Electrical generation • Concentrating solar power (CSP)
  7. 7. FUTURE TRENDS • POSITIVE - Experts estimate the sun’s ability to produce 10,000 times as much energy as the Earth produces - preoccupation and extensive research in this area • NEGATIVE - the challenge of creating solar plants because of the restricted sunny area - the challenge and expenses of the constructing new buildings and refitting old ones EXPECTATIONS - ´20 20 20´ EC strategy. - Solar thermal power industry will grow from 1,2 GW in 2009 to 14 GW in 2014
  8. 8. What can WE do? • In spite of all the progress, the future of energy lies in our own hands and actions:  installing solar panels  donating to research organizations in the field  studying science or engineering  voting for measures directed to alternative energy development
  9. 9. Solar energy in Romania In process, solar Romania’s climate The most plant construction : 210 sunny important solar projects – Covaci days/year & 1250 regions: Black Sea Solar Park (480 kWh/ m² of solar coast, Dobrogea 000 solar panals radiation and Oltenia and 35 MW capacity
  10. 10. Solar energy in Greece Smaller importance of The second Applications photovoltaic biggest market used almost applications in UE in solar exclusively for (capacity of collectors water heating 332 kWp in 2000)
  11. 11. Solar energy in Spain Public grants New laws for from regional Different civil and national situation into construction government the isles due to has developed helping the isolation of the solar citizens to set electric grids energy up panels
  12. 12. Solar energy in Poland 1000 W/m² Investment Now we have solar into solar 5% renewable radiation per panels will energy and by year paid off after 8 2020 we need years 15%
