Solar Energy is received by the earth through radiation. The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere. The incoming solar radiation to the earth is known as insolation.
Radiation is a process in which energetic particles or energetic waves travel through vacuum, or through matter-containing media that are not required for their propagation.
