INTRODUCTION
Solar power satellite
Placed in Geostationary orbit
Geostationary is located at space
It facing towards the sun
It Converts sunlight into electricity
Advantages of solar power satellite(S.P.S) over solar panel
No Effect of weather problems
Loss due to eclipses is also less
Energy received is 10 times more than solar panels
Occupies less very area compared to solar panels
It consists of large sheet of solar cells
Solar cells keep facing sun
Only moving part is transmitting antenna
Transmitter is array of radio tubes
Ground based rectenna consists of antennas
ADVANTAGES
Unaffected by day-night cycle, weather or seasons.
Provides 21 hour power supply per day.
This is an Eco-friendly, renewable and maintenance free energy resource unlike the conventional fuels.
As the equipment positioned in space, It occupies less area & unaffected by harsh weather conditions.
The space antenna could direct energy to rectenna on earth , which satisfy the energy requirements of all equatorial countries.
Waste heat is re-radiated back into space
No warming of biosphere due to dissipated heat.
CONCLUSION
More reliable than ground based solar power
So we can conclude that SPS is the one of the best way to face the demand of electricity.
If we develop this ,we need not bother about the exhaustion of natural resources
If this project succeeds it will become a boon to the next generations.
