India Braces For Impact Again
China’s shadow if set to grow longer on India’s solar manufacturing plans, with the solar giant planning a fresh set of restrictions on transfer of technology. Readers will be aware that India’s emergence as a key solar cell manufacturer has happened almost completely under the shadow of shadow boxing with China, as visa issues, and machinery restrictions at various points in the past two years slowed down many plans. The ame playbook is visible in battery cell manufacturing too, and now, apparently, in ingot and wafer manufacturing besides polysilicon itself. However, keep in mind that the final call might be restricted to the latest versions of these manufacturing technologies, which might yet offer an escape route to Indian firms seeking to build themselves.    
A Dominance That Is Unmatched 
China’s dominance of the global solar industry has long rested on a powerful combination of manufacturing scale, low costs, technological expertise and an integrated supply chain. That had meant an overall global market share of close to 80% or higher for all parts of the solar suppy chain for China over the past two decades. But as rival economies seek to replicate that model, Beijing appears increasingly determined to protect the technologies underpinning its lead.
On October 16, China proposed adding 12 photovoltaic manufacturing technologies to its list of technologies prohibited or restricted for export. The proposed measures cover technologies used in producing thin silicon wafers, advanced polysilicon, perovskite and tandem solar cells, while specified manufacturing processes for TOPCon, heterojunction (HJT) and back-contact cells would face export restrictions. There are no restrictions proposed on finished modules and cells however. 
The announcement came as Chinese solar exports continued to weaken. Exports of solar cells and panels by weight fell 6.4% year on year in September, according to Chinese customs data on October 18.
Taken together, the developments highlight a strategic challenge for Beijing: how to retain control over an industry in which China’s extraordinary manufacturing success has also created excess capacity, intense price competition and pressure on manufacturers’ profitability.
China’s proposed restrictions are significant because they target manufacturing know-how, not simply finished solar products. The distinction matters. Countries can import panels relatively easily, but building a competitive domestic industry requires access to production equipment, process engineering, manufacturing expertise and continual improvements in cell efficiency. The gradual weakening and demise of many European firms that offered the only non-Chinese alternative in many of these technologies has been notable in the past decade. 
The proposed restrictions on selected next-generation technologies are particularly noteworthy. Perovskite-silicon tandem cells offer the prospect of higher efficiencies than conventional silicon cells, while advances in wafer production and cell architectures can reduce costs and improve performance.
While China claims the proposed controls are intended to address national-security concerns and prevent sensitive technologies from being improperly transferredt the measures form part of a broader review of export controls covering technologies in sectors including artificial intelligence and biotechnology.
Public consultation is scheduled to run until November 15, 2026, and specified technologies would be subject to different levels of restriction. An interim registration requirement for certain technology transfers has, however, already taken effect.
The timing is important. China’s solar industry is dealing with a problem partly created by its own success: production capacity expanded faster than profitable demand could absorb it.
The International Energy Agency has documented how rapid capacity growth across the polysilicon, wafer, cell and module segments created a substantial manufacturing overhang, pushing down prices and profits. Competition among Chinese provinces and the shift towards more advanced cell technologies have added to the problem.
Last week,  SaurEnergy reported how five major manufacturers—LONGi, Trina Solar, JinkoSolar, JA Solar and Tongwei—employed 154,061 people at the end of 2025, down by 40,589, or approximately 21%, from a year earlier. This followed a substantial reduction across the dsame set of firms in 2024 as well. 
This is a striking contradiction: solar deployment continues to expand globally, yet some of the industry’s largest manufacturers are cutting jobs and struggling with losses.
September’s export decline adds another indicator of the pressure facing the sector. A single month’s fall does not establish a sustained trend, but it reinforces the need to examine whether global demand can absorb China’s enormous manufacturing capacity at remunerative prices.
For Beijing, protecting technology leadership may therefore have significance beyond preserving export revenues. It could help Chinese firms maintain an advantage as competing countries build factories, while retaining control over the next wave of manufacturing innovation.
India is directly exposed to the implications of the proposed controls. Its solar manufacturing ambitions increasingly extend beyond module assembly towards cells, wafers and a more integrated domestic supply chain. With the next key deadline June 2028, for ingots and wafer manufacturing domestically.
If access to Chinese manufacturing know-how becomes more restricted, Indian firms may face higher costs, longer development timelines and greater difficulty adopting advanced production processes. Projects relying on technology licensing, equipment transfers or Chinese technical assistance could be particularly affected, depending on the final rules.
But the development also reinforces the case for investing in domestic research and development, manufacturing equipment, process engineering and collaboration between industry and research institutions.
India should also avoid assuming that export restrictions will automatically create a competitive advantage for domestic manufacturers. Technology access is only one part of the equation. Scale, productivity, financing costs, supply-chain depth and the ability to sell into global markets will continue to determine competitiveness.
For India, (and the rest of the world)  the challenge is not merely to manufacture more panels. It is to develop the capabilities required to compete when access to the most advanced production technologies can no longer be taken for granted.
For India, that may be the most important takeaway from Beijing’s proposed export controls: manufacturing independence ultimately requires technological independence, not just more factories.
