India Unveils Major Global Solar Initiatives at ISA Assembly

India’s Global Solar Push at the ISA Assembly: New Platforms, Old Problems

On October 29, 2025, during the Eighth Assembly of the International Solar Alliance (ISA), India unveiled four groundbreaking initiatives designed to accelerate the global solar transformation. Among the new announcements was the SUNRISE platform, aimed at addressing the neglected issue of solar waste recycling and circularity. With over 78 million metric tonnes of solar panel waste projected globally by 2030, India’s assertion of leadership in upcycling is critically timed. Alongside, the high-profile relaunch of One Sun One World One Grid (OSOWOG)—a transcontinental clean energy network—signposts India’s ambitions to position itself as a convenor of the Global South ahead of COP30 next month in Brazil.

From Advocacy to Implementation: Breaking the Pattern

The initiatives signal a significant shift in ISA’s role, moving from broad advocacy to demonstrable implementation. For nearly a decade, the ISA has aspired to mobilize USD 1 trillion in solar investments by 2030, per its founding charter, but infrastructure-scaled action has been inconsistent. Until recently, ISA’s focus seemed skewed toward rhetorics of cooperation, with member contributions often scattered across pilot projects rather than scaled systems. The launch of specific mechanisms like the SIDS Procurement Platform, co-developed with the World Bank, and the Global Capability Centre (GCC) now offers a concrete toolbox—efficient solar procurement, cutting-edge R&D, and focused capacity development on a globally coordinated scale.

Moreover, the emphasis on circularity through the SUNRISE initiative challenges conventional solar narratives which have turned a blind eye to resource recovery. This approach departs from earlier initiatives that saw sustainability narrowly framed as energy access and affordability, leaving environmental externalities unaddressed.

The Machinery Behind the Ambition

Institutionally, ISA’s capacity to execute these ambitions remains constrained by its budgetary and legal matrix. The ISA Framework Agreement and subsequent amendments passed in 2020 allow cooperative financing, but remain ambiguous regarding binding obligations for members. Despite membership swelling to 125 countries, the organization runs on modest funding—just over $65 million annually, according to the Ministry of New and Renewable Energy (MNRE). Furthermore, ISA has yet to radically scale up private-sector partnerships for innovative financing models—a critical gap.

The SIDS Procurement Platform, for example, intends to consolidate solar procurement for Small Island Developing States. While impactful in theory, such coordination has historically faced implementation challenges due to fragmented procurement systems and differing policy environments. The parallels with India’s domestic solar policy complications—where mismatched tariff structures impede coordinated energy pricing—suggest potential hurdles.

What the Data Speaks Versus the Headlines

ISA’s rhetoric this week leaned heavily on global solar investment statistics, citing USD 521 billion in solar financing globally in 2024. While impressive, this figure hides critical nuances. Only 41% of investments in solar came from low- or middle-income countries, per ISA’s "Ease of Doing Solar" metric. Within ISA member countries, financing flows remain clustered in high-capacity regions (e.g., South Africa, Brazil), while smaller members in Sub-Saharan Africa and Pacific areas remain under-resourced. The SUNRISE initiative, though promising, fails to elucidate clear funding mechanisms for upcycling R&D beyond generic commitments. Recycling solar waste demands expensive technology adaptation, particularly if India intends to set regulatory benchmarks on material recovery efficiency.

Then there's the much-heralded OSOWOG plan, connecting continents from East Asia to Europe. Its promise of "energy resilience" overlooks the geopolitical challenges of cross-border energy trade. Europe’s ongoing struggles integrating grid-dependent renewables, particularly in Eastern and Mediterranean regions, could foreshadow problems for ISA proposals.

The Questions Nobody Is Asking

The trouble lies not with ISA’s vision, but its operational feasibility. Who precisely shoulders the financial and infrastructural burden of these initiatives? ISA may be headquartered in India, but its governance relies only minimally on Indian funding, leaving much to voluntary contributions from member states. Given the resource limitations of countries in the Global South, how realistic are the timelines? For instance, recycling technologies proposed under SUNRISE might be viable for middle-income economies like South Africa, but prohibitively expensive for smaller economies like Malawi.

Moreover, ISA’s proposed focus on capacity-building through the Global Capability Centre mirrors a prior UN initiative (IRENA’s Renewable Readiness Assessment) that faltered precisely because local institutions lacked absorptive capacity for technology transfer. An honest inventory of where ISA’s on-ground presence in member states stands today would reveal stark gaps—in technical manpower, regulatory agencies, and supply chain adaptability.

South Korea’s Solar Strategy: Lessons in Long-Term Planning

For ISA’s aspirations to take off, it might draw lessons from South Korea’s solar advancement post-2018. Unlike ISA’s broad, transcontinental frameworks, South Korea implemented focused national programs tied to industrial geology. For example, it built a dedicated solar waste management system through its Electronics Recycling Act—mandating recovery targets, alongside state-subsidized R&D for recyclables. India’s ISA-led SUNRISE remains conceptually critical, but legally unregulated by binding guidelines on solar waste disposal in member economies.
