Solar diplomacy got a concrete new chapter on Friday, 6 November 2026, when Union Minister for New and Renewable Energy Pralhad Joshi sat down with H.E. Arkam Ilyas, Sri Lanka's Deputy Minister of Energy, to map out a sharper, project-driven future for India–Sri Lanka cooperation under the International Solar Alliance (ISA).

The meeting, held on the sidelines of the #BRESummit2026 and the 9th ISA Assembly, ranged across a striking breadth of technical ground: solar integration into existing grids, energy storage solutions, digital grid management, floating solar installations, and agricultural solarisation. Joshi described it as an 'engaging meeting', and the agenda backed that up — these are not aspirational talking points but working domains where both nations have already signalled intent.

STAR-C at Moratuwa: turning a partnership into a lab

The sharpest deliverable on the table is the operationalisation of the STAR-C (Solar Technology Application Resource Centre) collaboration with the University of Moratuwa, Sri Lanka's leading technical institution. STAR-C is an ISA capacity-building initiative that embeds solar technology expertise directly inside member-country universities — making knowledge transfer structural rather than episodic. Getting Moratuwa's centre fully live would give Sri Lankan engineers and policymakers a standing institutional resource, not just a bilateral promise.

The ISA itself was co-launched by India and France at COP21 in 2015 and has since grown into a multilateral platform for solar investment and technology sharing. India has consistently used the alliance as a vehicle for renewable energy diplomacy with its neighbours, and Friday's meeting slots neatly into that pattern — but with a post-crisis urgency that earlier engagements lacked.

Why Sri Lanka's energy transition matters right now

Sri Lanka's economy went through a severe crisis in 2022, and energy sector stabilisation remains central to its recovery. The island nation is pushing to diversify away from expensive fossil-fuel imports, and solar — given its geography and solar irradiance — is a logical anchor for that shift. India's neighbourhood-first approach means New Delhi has a strategic interest in that transition succeeding: a stable, energy-secure Sri Lanka is a more reliable partner across trade, connectivity, and regional diplomacy.

Floating solar and agri-solarisation are particularly significant here. Floating solar arrays on reservoirs reduce land-use conflicts on a densely populated island; agri-solarisation allows farmers to generate power without sacrificing cultivable land — a dual dividend that can accelerate rural electrification without political friction.

Reaffirming commitment at the 9th ISA Assembly

Joshi explicitly 'reaffirmed India's commitment to supporting Sri Lanka's renewable energy transition through practical cooperation and knowledge-sharing' — language calibrated for the multilateral audience of the ISA Assembly. The emphasis on 'practical cooperation' and 'concrete projects' signals that both sides want to move from frameworks to signed agreements and funded initiatives. The 9th ISA Assembly provides the institutional moment to do exactly that, with member-state ministers, development finance institutions, and solar industry representatives all in the same room.

Whether the STAR-C centre at Moratuwa gets a launch date, or whether a grid-interconnection pilot clears its final technical hurdles, the next few days of the Assembly could translate Friday's bilateral into something with a budget line and a deadline.
