Over 120 nations are members of the International Solar Alliance (ISA). It is a collection of countries that benefits from more than 300 days of sunshine because it is situated halfway between the Tropics of Cancer and Capricorn. The ISA’s head office is located in Gurgaon, India. The first organisation in the world to exclusively focus on solar energy is ISA.
ISA serves as a forum for cooperation in the area of energy security in nations with warm climates. The alliance’s main goal is to lessen reliance on fossil fuels by working together to maximise the use of solar energy. The ISA seeks to create applications for cost-effective solar technologies. ISA is also expected to mobilise $1 trillion for funding solar energy projects by 2030.
Prime Minister Narendra Modi originally proposed this idea at a speech at London’s Wembley Stadium. On November 30, 2015, at the 21st session of the United Nations Climate Change Conference of the Parties (COP-21) in Paris, France, Indian Prime Minister Narendra Modi and former French President Francois Hollande announced the formation of the International Solar Alliance.
India will host ISA’s main office. At the National Institute of Solar Energy (NISE), Gwalpahari, Gurgaon, the ISA’s interim Secretariat is based. For the next five years, India has committed a fund of 100 crores and provided secretarial help worth 225 crores.
Currently, 81 countries have signed and ratified the ISA Framework Agreement. There are 102 countries that have signed the ISA Framework Agreement. The alliance is an intergovernmental group based on treaties. Countries beyond the Tropics are welcome to join the alliance and take advantage of all its benefits, with the exception of voting rights.

The alliance has pledged $1 trillion in investment and is dedicated to lowering the cost of solar energy for isolated and difficult-to-reach populations. The cooperation will help India reach its objective of producing 175 GW of renewable energy and 100 GW of solar energy by 2022. The nations will aid one another in high-level tasks like research and development. Additionally, it is viewed as an alliance of developing nations in order to create a unified front and conduct research and development for manufacturing solar power equipment in poor nations.
