The Earth receives 174 Petawatts (PW) of incoming solar radiation at the upper atmosphere. Approximately 30 % of its radiation is reflected back to space while the rest of 71 % (124 PW) is absorbed by clouds, oceans and land masses. The world cumulative solar PV installed capacity reached almost 398 Gigawatts (GW) in 2018. This is only about 0.3 % of solar energy utilization from the sun. There is a wide gap of utilization is noticed due to lack of technology. In 1931 selenium cell efficiency of 1% invented then in 1980 thin films cell efficiency of 6-7% introduced. After 2013, efficiency of 18 to 21% achieved by crystalline silicon technology. In India, the installed capacity of till 2018 is of 350 GW which includes renewable and non-renewable energy sources. In that the cumulative installed solar capacity is only about 25 GW. By 2022, India wants to install 175 Gigawatt (GW) of renewable power capacity which corresponds to around half of its total electricity production.
