this is a small ppt about SOLAR POWER.. i think it may useful to all of us..

2. CONTENTS INTRODUCTION TO SOLAR ENERGY SOLAR COLLECTORS SOLAR PHOTO VOLTAICS DESIGN OF BUILDINGS TECHNOLOGY DEVELOPMENT TRADES ADVANTAGES AND DISADVANTAGES CONCLUSION

3. SOLAR POWER

4. 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.

5. 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.

7. 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

8. SOLAR COLLECTORS Non-concentrating Concentrating

9. 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

10. Evacuated collectors

11. CONCENTRATING

13. Heating and cool of residential buildings

14. Solar cookers

15. Solar engines for water pumping

16. Food refrigeration

17. Solar vehicles

19. 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.

20. THE HOUSE OF THE FUTURE:

21. Technology development trades Integration of solar energy in buildings. Solar lights. Solar city demo in boding. Solar drying technique. Thermal power generation.

22. Advantages Electric bills are dramatically drop. -No power outages. -No pollutants. DISADVANTAGES -sun does not shine consistently. -solar energy is a diffuse source.

23. 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.
