Nowadays electronic circuits are widely used which in turn increased the demand for power in future. Solar energy, which is non-renewable energy can be used. But only 1/100th part of total solar energy is received on the earth. There are many satellites which are being used for many applications. A Satellite with a specific application for generating power from solar energy is proposed which can be used to transmit the stored energy to the earth station in the form of microwaves (RF signal). This kind of satellites are called as solar power satellites (SPS) and these are placed in LEO/MEO so that they would be able to face the sun 99% of the time. These Solar Power Satellites collect energy from the sun and convert them to DC power and stores in a battery reserve. This DC power from the battery reserve can be converted into RF energy of required frequency using a device called Magnetron and the converted power is transmitted to the earth station antenna which is coupled to an array of Rectifier circuit so that the received RF power is then converted to DC energy. The motive behind the Solar power satellites is environmental pollution due to carbon dioxide emissions from thermal power plants and global warming.
