The Prime Minister said of the 121 countries associated with ISA, 61 have joined the alliance and 32 have ratified the Framework Agreement.
The NDB and the ISA agreed to consider a roadmap for the mobilisation of financing to promote solar energy in countries of common interest and to explore mechanisms for supporting solar energy development.
Addressing the plenary session of the conference at which 23 heads of nations and 10 ministerial representatives were present in New Delhi, Prime Minister Modi said there should be a full ecosystem for availability and development of technology, economic resources, and development of storage technology, mass manufacturing and innovation. "While solar is fast becoming one of the most cost-effective ways to generate new power and deliver energy access, to deploy fast enough, complementarity must exist between our work and the broader renewable energy mandate and development tools established by IRENA".
The ISA aims to create 1,000 gigawatts (GW, or 1,000 MW) of solar power capacity by 2030, and mobilise $1 trillion for this.
During the summit, New Delhi also announced 27 solar projects under the Indian government's credit lines in 15 countries, including Bangladesh, Chad, Congo, Ghana, Mali, Rwanda and Sri Lanka.
Macron, who arrived in India Saturday on a three-day official visit, has pledged an extra €700 million ($861.5 million) for solar energy projects in developing nations.
Macron applauded India's efforts in expanding renewable energy capacity within two years, from 39GW to 63GW, with solar energy growing up by 140%. To date, 121 countries are involved in the International Solar Alliance.
French President Emmanuel Macron has taken a swipe at Donald Trump for withdrawing from the Paris climate agreement.
Without directly mentioning Trump, Macron praised the "solar mamas", a group of women trained as solar engineers, saying that the women had continued their mission to promote solar energy even after "some countries decided just to leave the floor and leave the Paris Agreement". "They made a decision to act and keep acting", he said.
"We have to ensure that a better and affordable solar technology is easily accessible to everyone", he said.
Furthermore, the UAE Energy Strategy 2050 targets increasing the contribution of clean energy in the overall national energy mix to 50 percent by 2050, saving US$190 billion of the overall energy costs until 2050. The UAE has also launched many initiatives to provide the necessary funding to carry out and develop renewable energy generation projects, such as the initiatives taken by Abu Dhabi Fund for Development and Masdar. Regulatory aspects as well as standards have to be framed which will expedite adoption of solar solutions, Modi said, adding that consultancy support has to be development for putting up bankable solar projects in developing countries.
