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.
Conventional buildings don’t have sustainability because of the approach of designing and the construction method. The total energy consumption calculates for all buildings account for up to 40% in India, and commercial and residential real estate combined will account for more than 2000 TWH of energy consumption by 2030. India has an expected energy deficit of around 12% which is one of the major hurdles for the government. This will result in a further inc
