Introduction Space-based solar power (SBSP) is

the concept of collecting solar power in space for use on Earth.

SBSP would differ from current  solar  collection methods in that the means used to collect energy  would reside on an orbiting satellite instead of on Earth's surface.

History

The SBSP concept, originally known as satellite solar-power system (SSPS), was first described in November 1968.

Satellite A satellite is an artificial object

which has been intentionally placed into orbit such object are some times called artificial satellite.

Main Aim of the S.B.S.P system A means of collecting solar power in

space, for example via solar concentrators, solar cells .

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 (rectenna)

distributed to the earth

Solar satellite Large arrays of photovoltaic cells

mounted on a satellite.

Sun light will be capture and converted into electricity by photovoltaic panel.

Panel will remain in sun light 24 hours a day. Producing a constant source of base load power.

Energy transmitted to the earth There is no transmission losses

so each satellite is able to deliver a quantity of power similar to the nuclear power plant.

This energy will safely transmitted by the radio waves.

Energy received. This energy is received on the

earth by large easy to assemble grids called rectenna. and it convert from microwave to electricity then distribute it.

Rectenna A rectenna is a rectifying

antenna a spatial types of antenna. That is used to convert microwave energy into electricity.

They are used in wireless power transmission that transmitted power by radio waves.

Advantages Eliminationof plant and wildlife

 interference.

There is no air in space, so the collecting surfaces could receive much more intense sunlight.

A satellite could be illuminated over 99% of the time, and be in Earth's shadow on only 75 minutes per night at the spring and fall equinoxes.

Disadvantages The large cost of launching a

satellite into space.

The space environment is hostile ; panels suffer about 8 times the degradation they would on Earth.
