Accelerating the global deployment of solar energy

There are still many political, regulatory, technical and financial obstacles to the deployment of solar energy projects, especially in developing countries. The ISA aims to tackle these obstacles by drawing on the expertise of major technical and financial institutions, sharing knowledge and best practices and ensuring that member countries take ownership of these challenges at the highest political level.

The ultimate objective of the ISA, which was launched at the COP 21, is to support the addition of one thousand gigawatts to solar capacity and to raise more than one thousand billion dollars of investments by 2030.

The International Solar Alliance trains local stakeholders, advocates for financing mobilization, shares technical know-how and raises awareness on solar energy solutions in those industries that are most strategic for member countries. The objective is to support member countries identify fundable projects and ensure their implementation.

We are at a point in history where we can make an effective nudge towards ensuring that we focus not just on renewable energy but on responsible renewable energy.
Dr Ajay Mathur, Director General of the International Solar Alliance

At the One Planet Summitin Nairobi, Kenya in 2019, the French Development Agency (AFD) announced that it would increase its financing of the International Solar Alliance (ISA) solar projects to reach $ 1.5 B by 2022.

The Alliance is working closely with multilateral development banks (MDBs) and development finance institutions (DFIs) to build a roadmap for mobilizing $1,000 billion by 2030.

The International Solar Alliance’s two main courses of action which are supported by France are: 

  • to reduce financial risk relating to solar projects investment, in particular as part of the Sustainable Renewables Risk Mitigation Initiative (SRMI) launched in 2019 with the World Bank and the Agence Française de Développement;
  • to provide training and capacity building via the Solar Technology Applications Resources Center (STAR-C). 

The ISA has also developed industry-specific programmes aimed at improving service provision in a number of solar market segments (applications in agriculture, small networks, solar roofing, smart mobility, solar farms, solar cooling).

The International Solar Alliance is based on a framework agreement. Since 2020, membership has been open to all United Nations members. 

Key decisions and strategic guidelines are approved at the annual Assembly. The Permanent Committee and four Regional Committees make preparations for the assembly. 
The Secretariat, headed by the Director General, heads the activities and management.

To date, the ISA has 97 member countries and 21 countries are in the process of joining. The ISA also has a large number of international institutional partners

Each year, the ISA Secretariat publishes a reports of activity and on solar opportunities, which can be found here:
