The launch will coincide with a summit of world leaders at the start of two weeks of talks on the outskirts of Paris to seek a new global deal on curbing climate change, by shifting from fossil fuels towards renewable energy.

An Indian government statement on Sunday said there were well over 100 solar-rich countries in the tropics that could be members of the International Solar Alliance to develop clean and affordable solar energy.

Aware of the shadow cast by the failure of the 2009 Copenhagen summit, the last attempt to reach a global climate deal, the United Nations is placing as much weight on the efforts of individual governments as on an overarching UN Agreement.

India's national plan focuses on solar, saying it is expected to grow significantly. The aim is to reach capacity of 100 gigawatts by 2022, to be scaled up further in the future.
