solar energy uses
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. SSPS consists of a space-based power generation/transmission facility that gathers sunlight, converts it into microwaves or laser beams, and transmits those to the ground; and a power receiving facility on the ground.
Space-based solar power essentially consists of three elements:
• a means of collecting solar power in space, for example via solar cells or a heat engine
• a means of transmitting power to earth, for example via microwave or laser
• a means of receiving power on earth, for example via a microwave antenna
SBSP uses photovoltaic conversion, which uses semiconductor cells to directly convert photons into electrical power.
ADVANTAGES
There is no air in space, so the collecting surfaces could receive much more intense sunlight, unobstructed by the filtering effects of atmospheric, cloud cover, and other weather events.
Orbiting satellites can be exposed to a consistently high degree of solar radiation, generally for 24 hours per day, whereas surface panels can collect for 12 hours per day at most
Space solar power can be exported to any place in the world, and its energy can be converted for local needs. Space solar power will not produce hazardous waste
DISADVANTAGES
• The large cost of launching a satellite into space and The large size and corresponding cost of the receiving station on the ground
• Maintenance of an earth-based solar panel is relatively simple, but performing maintenance on a solar panel in space incurs the extra cost of transporting a team of astronauts into space.
• Space debris is a major hazard to large objects in space, and all large structures such as SBSP systems have been mentioned as potential sources of orbital debris.
