China’s new export curbs have exposed how far India’s solar and battery makers depend on Chinese machinery, and manufacturers are now scouting for alternatives in Europe, Japan and South Korea. The India solar battery machinery dependence was laid bare by Beijing’s move in October to restrict 12 solar manufacturing technologies, and Moneycontrol reported on 10 November that the curbs reach deep into the equipment Indian factories need. India can assemble solar modules at scale, but it still buys most of its cells, wafers and factory tools from China.
The curbs came in a joint announcement on 16 October from China’s Ministry of Commerce and its Ministry of Science and Technology. The order bans the export of manufacturing processes for perovskite-silicon tandem cells and large-area single-junction perovskite modules, and it puts licensing rules on high-end crystalline silicon technologies, including TOPCon, heterojunction and back-contact cells. China said the technologies also have uses in aerospace, defence and other sensitive sectors, and need closer monitoring. The India solar battery machinery dependence covers the tools as well as the technology, and those rules land directly on Indian factory plans.
The gap in India’s own capacity is wide. As of June 2026, India had about 262 gigawatts of solar module manufacturing capacity, but only about 37 gigawatts of cell capacity, about 2 gigawatts of ingot and wafer capacity, and no polysilicon capacity at all, according to Chetan Shah, chairman and managing director of Solex Energy. China controls an estimated 75 to 90 per cent of the global solar supply chain, Shah said, and China supplies about 95 per cent of the cells India imports and about 90 per cent of its factory tools. The India solar battery machinery dependence starts with that imbalance: modules are made in India, but the chain behind them is not.
India solar battery machinery dependence and the battery chain
Batteries carry the same problem. Chinese lithium iron phosphate cells are about 30 per cent cheaper than domestic or Western cells as of late 2026, and China controls 75 per cent of purified phosphoric acid and 95 per cent of battery-grade manganese sulphate, two inputs battery makers need. A separate licensing regime from November 2026 covers capital goods used in solar equipment and heavy machinery, including tunnel boring machines, and India’s trade deficit with China has crossed $100 billion this fiscal year. The India solar battery machinery dependence is therefore not a single import line but a chain of them, from cells to chemicals to the machines that make both. The India solar battery machinery dependence runs through every link of that chain.
Industry voices say the immediate hit to module output should be small, because existing plants already have their tools, but new capacity is where the curbs bite. Vinay Rustagi, chief business officer at Premier Energies, expects the curbs to be graded by how advanced the technology is, with newer and more efficient technologies facing stricter limits. Arulkumar Shanmugasundram, chief executive of SWELECT Energy Systems, said ingots face the most heat, since China holds a near monopoly over their production and the equipment used to make them. The India solar battery machinery dependence will show first in projects that planned to move upstream into cells, ingots, wafers and polysilicon.
India solar battery machinery dependence and the search for alternatives
Manufacturers are looking elsewhere. High-precision gear from Germany, Switzerland and South Korea offers a way out, but it usually costs 15 to 20 per cent more than Chinese equipment, and some estimates put the premium at 20 to 40 per cent, given limited supply and higher technology costs outside China. Amit Manohar, secretary general of the Indian Solar Manufacturers Association, said Germany, Japan, Taiwan, South Korea and the United States offer valuable skill in equipment, materials and advanced cell processes, and that Indian makers are well placed to widen those partnerships. The India solar battery machinery dependence has pushed firms to weigh dearer tools against the risk of relying on one supplier.
The government is moving too. The Department for Promotion of Industry and Internal Trade has launched a drive to indigenise 100 critical items spanning intermediates and capital goods across sectors, in response to China’s proposed curbs. Shah has called for the ALMM-II order, which requires makers to source made-in-India cells from an approved list, to be extended by at least 12 months, and for dedicated production-linked incentives, capital subsidies and a manufacturing push for critical photovoltaic equipment, spares and consumables. He also urged technology partnerships with the United States, the European Union, Japan, Korea and Taiwan, and work with Indian capital goods firms, CSIR laboratories and IITs. The India solar battery machinery dependence will not close quickly: domestic tooling is expected to take until 2028 to mature, and the gap years will test how far Indian makers can diversify.
