    SOLAR PHOTO VOLTAICS
    DESIGN OF BUILDINGS
    TECHNOLOGY DEVELOPMENT TRADES
    ADVANTAGES AND DISADVANTAGES
    CONCLUSION
  • SOLAR POWER
  • SOLAR ENERGY
    The Solar energy originates with the thermonuclear fusion reaction occur in the Sun.
    AUGUST MOUCHOT was the first person to develop a system that uses solar power in 1878.
    Solar energy has greatest potential of all the sources of the Renewable energy.
  • The solar power where sun hits the Atmosphere is 1017 watts.
    It comes to earth with 1016watts
    The world wide power demand of all the needs of civilization is 1013 watts
    There fore the Sun gives us 1000 times more power than we need.
  • Non- Renewable Energy
    Natural resources such as coal, petroleum, oil and natural gas take thousands of years to form naturally and cannot be replaced as fast as they are being consumed.
    Coal
    Oil Rig Collecting Petroleum
  • SOLAR COLLECTORS
    Non-concentrating Concentrating
  • NON-CONCENTRATING
    FLAT PLATE COLLECTORS.
    They are made in rectangular panels, from about 1.7 2.9 sq.m in area and relatively simple to construct.
    Flat plates can collect and absorb both direct and diffuse solar radiation
  • Evacuated collectors
  • CONCENTRATING
  • Applications Of Solar Energy
    • Solar water heating
    • Heating and cool of residential buildings
    • Solar cookers
    • Solar engines for water pumping
    • Food refrigeration
    • Solar vehicles
    • SOLAR PHOTOVOLTAIC CELLS
  • SOLAR PHOTOVOLTAICS
    An increasingly popular use of solar energy involves solar electric systems, called Photovoltaics.
    Photovoltaic (PV) systems convert sunlight directly into electricity, and are potentially one of the most useful of the renewable energy technologies.
  • Design of buildings
    Placement of room-types, internal doors & walls, & equipment in the house.
    Orienting the building to face the equator.
    Extending the building dimension along the east/west axis.
    Adequately sizing windows to face the midday sun in the winter, and be shaded in the summer.
  • THE HOUSE OF THE FUTURE:
  • Technology development trades
    Integration of solar energy in buildings.
    Solar lights.
    Solar city demo in boding.
    Solar drying technique.
    Thermal power generation.
  • Advantages
    Electric bills are dramatically drop.
    -No power outages.
    -No pollutants.
    DISADVANTAGES
    -sun does not shine consistently.
    -solar energy is a diffuse source.
  • Final Thought
    Argument that sun provides power only during the day is countered by the fact that 70% of energy demand is during daytime hours.
    At night, traditional methods can be used to generate the electricity.
    Goal is to decrease our dependence on fossil fuels.
    Currently, 75% of our electrical power is generated by coal-burning and nuclear power plants.
    Decrease of acid rain, carbon dioxide
    pollution free, indefinitely sustainable.
  • Earth’s Non – renewable
    Resources Are
    Getting Used Up!
    To Save Them,
    Follow 3 Simple Steps:
    Save, Recycle And Grow Trees
