Solar System / Universe
Stars like Sun have a lifetime of about 11 billion years. Its tremendous amount of hydrogen present at the core creates fusion providing the energy to light the planet Earth. Sun does undergo fusion to emit light with the help of the hydrogen atoms present inside its core. While about 5.5 billion years guaranteed till touchdown occurs when there is no more hydrogen to light up the Earth, it is time that we consider to make use of this unique, omnipresent, massive and significant source of energy available to us.

Producing electricity from solar radiation can be classified on the type of conversion technology into two broad categories.
