Environmental - Directly serves SDG-7 (Affordable & Clean Energy) and SDG-13 (Climate Action). - Aligned with India's Panchamrit commitments at COP26: 500 GW non-fossil capacity by 2030; net-zero by 2070.
Economic - Targets USD 1 trillion solar investment mobilisation by 2030. - ISA Solar Facility — payment guarantee mechanism to de-risk solar investments in Africa. - 2026 launch: Green Hydrogen and Storage Start-up Challenge to enable technology transfer and market access in member countries [S1].
Scientific / Technological - Flagship programmes: STAR-C (Solar Technology Application Resource Centre), SolarX Grand Challenge for startups, Solar Awards. - Promotes solar mini-grids, solar pumps, rooftop solar, e-mobility, green hydrogen.

- GS-III: Infrastructure — Energy; Conservation, environmental pollution and degradation; Climate change.
- Plausible question stems: 1. "The International Solar Alliance is more than a renewable energy platform; it is an instrument of India's climate diplomacy." Discuss. 2. "Assess the role of ISA in achieving India's Panchamrit commitments and SDG-7 in the Global South." 3. "Examine the institutional architecture and financing challenges before the ISA in mobilising USD 1 trillion in solar investments by 2030."
