Indian Prime Minister Narendra Modi has launched a global solar alliance with French President François Hollande at COP21 in Paris.
The International Agency for Solar Technologies & Applications aims to help countries in the tropics boost solar projects.
India’s Government is investing $30 million (£20m) to build the headquarters in the country.
A total of 120 countries have signed up to the international initiative.
Mr Modi said: “It will create unlimited economic opportunities that will be the foundation of a new economy of the century. This is an alliance that brings together develop and developing countries, governments and industries, laboratories and institutions in a common enterprise.”
India aims to generate 40% of its energy from non-fossil fuels by 2030.
