Architecture of Action
Strategic Pillars of ISA
Catalytic Finance Hub
The Hub will provide catalytic and blended finance to mitigate risk and attract private investment across Asia-Pacific, Latin America, and the Caribbean, building on the success of the Africa Solar Facility under the Global Solar Facility.
Global Capability Centre and Digitisation
Pursuing a "Silicon Valley for Solar" vision in India, the initiative links national centres of excellence including STAR-C through a hub-and-spoke model, mainstreaming innovation via the SolarX Startup Challenge and replicating proven solar models globally to reduce fossil fuel dependence.
Regional and Country-Level Engagement
Through platforms such as the SIDS Platform, the initiative will advance e-tendering and e-procurement for aggregation and scaling, while deepening engagement with Member Countries across ISA's ten programmes.
Technology Roadmap and Policy
To accelerate solar energy uptake across ISA Member Countries, the initiative will address supply chain diversification and emerging technologies, including solar PV, AgriPV, Floating PV, BIPV, battery storage, E-Mobility, green hydrogen, grid interconnection, and solar heating and cooling.
