  1. 1. A.I.E.T (ALWAR) Presenting by- Ravi Yadav
  2. 2. Renewable energy :- Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat. which are renewable (naturally replenished) Renewable energy provides 19% of electricity generation worldwide.
  3. 3. Types :- Wind power Hydropower Solar energy Biomass Biofuel Geothermal energy
  4. 4. Solar Energy :- Solar energy is the energy derived from the sun through the form of solar radiation. Solar powered electrical generation relies on photovoltaic.e.g.:- Solar photovoltaic cells(solar panels), Heat Engine, solar heat collectors Solar energy utilization
  5. 5. Why it is required soon ? From last century mostly the power is produced by Hydro Carbon fuel. Conventional and Hydro Carbon energy resources are constant in nature . Soon conventional resource will go to finish . Sun power is longtime and reliable , (it have very long term commitment)
  6. 6. Top oil Importers :-
  7. 7. How it produce Electricity ? (by solar panels)
  8. 8. Solar panels- Flat plate solar collectors system Concentrated photovoltaics (CPV) systems1. CVP-
  9. 9. Concentrated solar power:- also called concentrating solar power and CSP systems use mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a small area. Electrical power is produced when the concentrated light is converted to heat, which drives a heat engine connected to an electrical power generator
  10. 10. Photovoltaic Power Plants type- Ground based solar system Space solar power (SSP) system
  11. 11. SSP- SOLAR SPACE POWER Space-based solar power (SBSP) is the concept of collecting solar power in space for use on Earth It has been in research since the early 1970s. The SBSP concept, originally known as Satellite Solar Power System (SSPS),
  12. 12. SSP Built in Components :- A Satellite Concentrating mirrors Photovoltaic cell convertor (sunlight to Electricity) Microwave transmitter / LASER Transmitter Microwave/ LASER converter (MW to Electricity) ** Power controller & distribution
  13. 13. Method:- It use the method of collecting the Solar power in space and then supply on to the Earth by means of transmitting power in the form of Microwaves , LASER beam. method of transmitting power over long distances . (e.g., from an SPS to Earths surface) using microwaves from a very large antenna (up to one square kilometer) on the satellite to a much larger one, now known as a rectenna, on the ground.
  14. 14. The SSP concept :-
  15. 15. Why in Space ?
  16. 16. • No air & clouds in space, so the collecting surfaces could receive much more intense sunlight, unobstructed by weather A satellite could be illuminated over 99% of the time (Earths shadow on satellite comes only 16 minutes) Higher collection rate: In space, collection in orbit is approximately 144% of the maximum attainable on Earths surface. Longer collection period:
