  1. USES OF SOLAR ENERGY PRESENTED BY, J M VIRGIN MARY PHYSICAL SCIENCE ST JACOB’S TRAINING COLLEGE

  2. For photosynthesis. • For drying clothes. • For cooking food. • For heating water. • For generating electricity. What are the uses of Solar energy?

  3. Guess the picture? Solar pannel

  4. SOLAR PANNEL • Electronic device. • Made by assembling solar cells. • Solar energy falls on one side of a solar cell,a small current is produced -photoelectric effect. • Electric current is stored in battery and used when required.

  5. Developed to provide electricity for satellites. • Used in calculators, street lights. • SPV produces electricity of 1000kw. Give some uses of solar energy?

  6. Guess the picture? solar water heater

  7. Heat from the sun is used to heat water. • water is pumped through blackened pipes into the glass panel. • Water is pumped at the bottom. • so convection helps the flow of hot water on the top.

  8. Guess the picture? SOLAR COOKER

  9. Can cook food as a conventional oven. • A basic solar cooker is an insulated box with a glass top. • Heat from sunlight gets trapped and cook food.

  10. Solar power plant Guess the picture?

  11. Generate electricity. • concave reflectors are used to focus sun's rays on blackened pipes with water. • water boils and becomes steam. • Steam rotates the turbine. • Generator attached to turbine is activated. • Guragon in haryana,capacity-500kw.

  12. Give the advantages of solar energy? • Long lasting. • Can be used almost everywhere. • Cost effective solution to energy issues. • Totally silent and non-polluting.

  13. High initial cost. • Require large area. • Silicon used in cells is expensive. Give the limitations of solar energy?
