From Galleons to Gigawatts: How China’s Solar Machine Made Silver Strategic
WRITTEN BY JASON TOGUT

Beginning in 1565, Manila galleons carried Chinese silk and porcelain eastward and massive quantities of New World silver westward from Spain’s colonies in Mexico and Peru. The Ming state’s growing reliance on silver taxes had made China the world’s great silver sink, pulling a metal extracted in the Americas across the Pacific and helping create one of the first truly global commodity systems. Four and a half centuries later, China is again drawing silver into its economy, this time not to pay taxes but to print electrical contacts onto solar cells.
The analogy only goes so far. China does not control the world’s silver mines, and its manufacturers still depend on metal sourced abroad. But the scale of China’s solar industry is hard to overstate: its plants turned out 574.5 gigawatts of modules in 2025, roughly 83 per cent of world output. That means decisions made in its factories — how many cells to produce, how much silver paste to apply, and how quickly to substitute copper — can alter the balance of the global market. China’s role in the global silver market, then, rests less on what it controls at the mine than on what it decides at the furnace.
That is what makes silver strategically important. The issue is not Chinese ownership of the metal itself, but the power and the vulnerability created when industrial policy concentrates much of a commodity’s marginal demand within a single manufacturing ecosystem. China has not conquered silver; it has built an industrial machine that decides how much silver the solar build-out requires.
The silver in solar
Silver occupies an unusual place in global markets. It is both a precious metal and an industrial input. In photovoltaic cells, silver paste forms conductive lines that collect and carry the electrical current released when sunlight strikes the silicon wafer. Manufacturers use it because no other metal combines the same electrical conductivity, reliability, and ease of application at commercial scale.
The scale of solar deployment has created a new source of silver demand. According to the Silver Institute, photovoltaic manufacturing consumed a record 197.6 million ounces of silver in 2024. That was 17 per cent of total silver demand and 29 per cent of industrial demand. The solar sector did not single-handedly cause the market’s recent deficits, but it has grown large enough that changes in solar production could materially tighten or loosen the market.
For policymakers, silver shows why mineral security cannot be measured only at the mine mouth. Silver’s strategic importance does not depend on concentrated extraction; rather, risks associated with losing access can rise when downstream manufacturing is highly concentrated and one industrial system drives a large share of incremental demand.
Silver supply is poorly suited to respond quickly to changes in demand. Mexico remains the largest silver-mining country, while China is also a major producer. Much of the world’s silver, however, is extracted as a byproduct of lead, zinc, copper, and gold mining. A rise in silver price cannot automatically bring a flood of new metal onto the market because production often depends on investment decisions made for other commodities. This makes the market unusually sensitive to shifts in industrial demand.
The divergence of 2025, with record global installations alongside a 6 per cent fall in photovoltaic silver demand to 186.6 million ounces, showed why the relationship cannot be reduced to a simple claim that more solar always means more silver. Installations kept climbing, but silver use in photovoltaics fell as manufacturers accelerated thrifting and substitution in response to intense competition and higher metal costs. The same Chinese factories that had helped push silver demand to a record high were able to pull it back by using less metal. Silver’s strategic relevance lies precisely in this two-way interaction between industrial scale and technological adaptation.
China’s demand-side power
China did not build its solar position to gain leverage over silver. Silver demand is a consequence of a much larger industrial project. State-directed industrial policy and a vast domestic market allowed Chinese firms to scale every major stage of photovoltaic manufacturing. The International Energy Agency estimates that China accounts for more than 80 per cent of global capacity across the principal manufacturing stages, from polysilicon and wafers to cells and modules.
Domestic deployment reinforced that manufacturing base. China added about 278 gigawatts of solar capacity in 2024 and nearly 370 gigawatts in 2025. Installations at home absorbed enormous output, helped firms move down the cost curve, and supported an export industry that made solar panels cheaper around the world. Production and deployment became a feedback loop: policy created scale, scale lowered costs, and lower costs expanded both Chinese and global demand.
That ecosystem gives Beijing and Chinese manufacturers demand-side influence over silver without giving them control of silver supply. When Chinese cell production expands rapidly, it can absorb a meaningful share of incremental metal. When manufacturers change cell architecture or reduce silver loadings, they can suppress demand even as the number of panels rises. Commodity producers, traders, and investors must therefore follow Chinese industrial decisions because those decisions increasingly determine the market’s marginal barrel — or, in this case, its marginal ounce.
But influence is not immunity. China’s solar industry is also exposed to a commodity it does not dominate. A sustained silver shortage or price spike would squeeze already thin module margins, raise the cost of domestic deployment, and intensify the search for copper-based contacts and other substitutes. The relationship is one of mutual dependence: China shapes silver demand, while silver availability and price constrain China’s industrial ambitions.
Why the relationship matters
For policymakers, silver shows why mineral security cannot be measured only at the mine mouth. Silver’s strategic importance does not depend on concentrated extraction; rather, risks associated with losing access can rise when downstream manufacturing is highly concentrated and one industrial system drives a large share of incremental demand. The United States’ decision to add silver to the 2025 List of Critical Minerals recognises the economic costs that a disruption could impose. But the proper response is not necessarily to recreate the entire Chinese solar supply chain or to pursue silver autarky.
A more realistic resilience strategy would identify the points where disruption would be most damaging and where public policy can change the outcome. That includes diversifying silver sourcing and refining, improving recovery from industrial scrap and retired panels, supporting research into lower-silver and copper-metallisation technologies, and checking how quickly new cell designs are being adopted. It also means distinguishing the root vulnerability from its symptom. Silver did not cause Western countries to fall behind in solar manufacturing; China’s industrial ecosystem did. But silver is one of the constraints through which that concentration can transmit risk to the global energy transition.
For China, the policy implication runs in the opposite direction. The country’s manufacturing dominance has created a large exposure to foreign commodity markets. Accelerating substitution is therefore not merely a cost-saving exercise; it is a form of industrial security. The more silver-efficient Chinese producers become, the less vulnerable Beijing’s deployment targets are to a metal whose supply responds slowly and whose price is also driven by investment demand.
For investors, the lesson is that silver can no longer be analysed only through inflation, interest rates, jewelry demand, or safe-haven flows. Solar manufacturing is now a major, but technologically fluid, component of demand. The 2025 decline in photovoltaic silver use, despite continued growth in installations, showed that Chinese module margins, cell technology, production targets, and substitution rates can matter as much as the headline pace of solar deployment itself.
From sink to system
The history of silver has not come full circle, but it has begun to rhyme. Ming China pulled silver across the Pacific because its fiscal system created enormous monetary demand. Modern China pulls silver into factories because its industrial system creates enormous technological demand. In neither era did China need to own the mines to reshape global flows.
The difference is that modern China is not simply absorbing silver. Its manufacturers help decide the scale and intensity of its use. They can expand demand through unprecedented production and then reduce it through engineering. That is demand-side commodity power: not sovereignty over a resource, but the capacity to set the pace at which the world consumes it while depending on supply it does not control.
Silver is more than a niche input in solar panels and less than a tool of Chinese power. It is a case study in how industrial policy is changing the geography of commodity power. In the twenty-first century, strategic resources derive their importance not only from what lies underground, but also from what happens on factory floors.
