Global Solar Fleet Hits 3 Terawatts as India Races to Close Its Manufacturing Gap
The world added 664 GW of solar in 2025, but India's 17 GW annual manufacturing shortfall leaves its build programme exposed to Chinese supply-chain shifts.
The global solar fleet crossed 3 terawatts of installed capacity in early 2026, after a record 664 gigawatts of new photovoltaic capacity was added worldwide in 2025 — tripling total capacity in just four years, according to SolarPower Europe's Global Solar Market Outlook 2026-2030, published in the week of 2026-06-22.6
India is building more aggressively than almost anyone. Some 1,000 trucks a day jostle along a single-lane road near the Pakistan border to supply the Adani Group's Khavda renewable energy park, a 730-square-kilometre site designed to deliver 30 gigawatts of combined solar and wind capacity when complete — enough to cover roughly 4% of India's current electricity consumption. Construction began in 2023, with the first 551 megawatts coming online in February 2024; generation from the park currently stands at around 13 GW.2,5
The scale is deliberate and government-backed. India's $100 billion grid investment programme, which OilPrice.com reported on in July 2026 (2026-07-08), is accelerating both deployment and a domestic manufacturing push. A decade ago the country's solar sector barely existed beyond scattered microgrids and rooftop arrays; the Modi administration's pivot toward utility-scale deployment around 2015 has since rewritten the ambition entirely.8
But the manufacturing base has not kept pace with the build. Domestic solar-cell production capacity runs to around 3 gigawatts annually, against average demand of 20 GW — a gap of 17 GW that must be sourced from international markets, according to India's Ministry of New and Renewable Energy.1 That dependence on imports creates an exposure, particularly given how quickly China — the world's dominant panel supplier — is adjusting its own industry.
Beijing announced earlier this year it was halting approvals for some new domestic solar projects and cutting subsidies to developers, moves designed to cool an overheated domestic build-out. The slowdown is expected to redirect Chinese manufacturing toward export markets and reduce global panel prices. Industry experts cited by the Observer Research Foundation estimate module prices in India could fall by as much as 25% as a result.1 For Indian project developers, that reduction in equipment costs is straightforwardly useful. For India's domestic cell manufacturers, a 25% price cut from a better-capitalised Chinese competitor is a different kind of news entirely.
This is the dilemma the $100 billion programme has not resolved. Cheap Chinese imports keep the build costs manageable and the megawatt targets reachable; they also erode the economics of the domestic supply chain India is simultaneously trying to cultivate.8,1
The broader trajectory for solar remains steep regardless of where the panels originate. SolarPower Europe projects solar will become the world's largest source of electricity by 2032, with battery storage capacity reaching 3.8 terawatts by 2035.4 Some 511 GW of new capacity was added globally in 2025 alone, driven by cost declines that have made the technology competitive with fossil fuels across a widening range of markets, The Diplomat reported in April 2026 (2026-04-13).7
Projects are scaling accordingly. Until recently, benchmark solar developments were measured in hundreds of megawatts; now gigawatt-scale sites are under active construction or in permitting across multiple continents.3 The Khavda park, should it reach its 30 GW target, would represent a single site rivalling the total grid capacity of many mid-sized economies.5
For coal and gas markets, the displacement implications feed through slowly. India's current thermal dependence means any sustained slowdown in the solar build — financing constraints, grid infrastructure bottlenecks, or a disruption to Chinese supply — would extend coal demand further than the capacity headline numbers imply. Newcastle physical coal settled at $119.70 per tonne as of Friday's close (2026-07-18), a level that remains commercially viable for Indian thermal generators running well below the utilisation rates a faster renewables build would force.
The forward risk is whether India can convert access to cheap imported panels into domestic manufacturing capability, or whether it remains structurally reliant on Chinese supply through the decade. With module prices potentially falling another 25%, the economics favour importing rather than building local capacity — which keeps the dependence intact precisely when geopolitical relationships between the two countries are most subject to revision.1
