Industrial Silver Demand: Solar, EV, Electronics and Medical

What “industrial demand” for silver actually measures

The Silver Institute publishes the annual World Silver Survey (WSS), researched by the London consultancy Metals Focus. The survey defines total silver demand as the sum of four categories: physical investment (coins and bars), jewelry, silverware, and industrial fabrication. Industrial fabrication is by far the largest of the four.

Industrial fabrication itself breaks down into six reported end uses: electrical and electronics (which includes the photovoltaic subsector, brazing alloys and solders, other industrial applications, plus photography). Photovoltaics is disclosed as a subset of electrical and electronics because solar cells use silver conductive paste as an electrical contact. The other-industrial line captures a wide mix of small applications, including catalysts, mirrors, water purification, biocides, and the growing medical device segment.

According to the World Silver Survey 2025 (35th edition, published April 16, 2025, covering calendar 2024), industrial demand reached 680.5 million ounces in 2024. That was a 4% year-on-year increase and the fourth consecutive record. The World Silver Survey 2026 (36th edition, published April 15, 2026, covering calendar 2025) reported industrial demand of 657.4 Moz for 2025, a 3% decline driven mostly by softer photovoltaic off-take in China. Even after the pullback, 2025 was still the second-highest industrial demand year on record.

To put that in perspective, physical investment (coins and bars) totaled 190.9 Moz in 2024 and 165.1 Moz in 2025 per the same WSS reports. Industrial fabrication is roughly four times the size of retail investment demand and represents about 59% of total silver demand in a typical recent year.

Solar photovoltaics: the largest single growth engine

Solar cells use silver conductive paste screen-printed onto the front and back of each cell to collect and carry the electric current generated when photons hit the silicon. Silver is the metal of choice because it has the highest electrical and thermal conductivity of any element, and because the paste can be co-fired with the silicon wafer at high temperature without degrading the junction.

The World Silver Survey 2025 reported that photovoltaic demand for silver reached a record 197.6 Moz in 2024, up 9% year over year. The World Silver Survey 2026 shows PV demand at 174 Moz in 2025 (a decline of about 12% on lower Chinese module output and a modest reduction in per-cell silver loading from thrifting programs).

A joint December 2025 study by Oxford Economics and the Silver Institute, “Silver: The Next Generation Metal,” quantifies the structural shift plainly. The share of silver industrial demand attributable to photovoltaics rose from 11% in 2014 to 29% in 2024. In one decade, PV moved from a niche end use to the largest single sub-category inside industrial silver fabrication.

Two technology changes matter for future silver intensity per panel:

• Cell architecture. The industry is transitioning from PERC (Passivated Emitter and Rear Contact) cells to TOPCon (Tunnel Oxide Passivated Contact) and heterojunction (HJT) cells. TOPCon and HJT cells are more efficient but currently use more silver per cell than PERC. The net effect on total silver demand per gigawatt of installed capacity depends on how quickly per-cell thrifting research catches up with the architecture change.
• Copper metallization research. Several manufacturers are testing copper-plated contacts as a partial substitute for silver paste. Copper is far cheaper but harder to apply reliably without degrading the cell. Meaningful commercial displacement of silver in mainstream solar cells has not yet occurred and remains an open technical question.

Electronics: the invisible baseload

Electrical and electronics fabrication (excluding the photovoltaic subset) is the second-largest industrial end use of silver. The World Silver Survey 2025 reports total electrical and electronics demand of 445.1 Moz in 2024, which nets to roughly 247.5 Moz of non-PV electronics after removing the 197.6 Moz PV line.

Silver’s role in electronics is baseload rather than glamorous. Every printed circuit board with silver-bearing solder, every high-end capacitor and switch, every RFID antenna, every 5G base station and radio-frequency component, every membrane keypad, every conductive ink for flexible displays and printed sensors uses small amounts of silver. Individual devices contain milligrams. The category is huge because the world builds billions of devices per year.

Three long-running trends keep this line growing:

• Data center build-out. Oxford Economics and the Silver Institute report that global data center IT power capacity grew from 0.93 GW in 2000 to about 50 GW in 2025. Data centers are dense with server hardware, networking equipment, and power electronics, all of which carry silver-bearing components.
• 5G and next-generation wireless. Higher-frequency radios use more silver-containing components per base station than the 4G equipment they replace. Each new generation of wireless infrastructure pushes silver-per-cell-site higher.
• Printed and flexible electronics. Silver conductive inks are the workhorse for printed antennas, wearable sensors, automotive touch surfaces, and RFID tags. This is a small but rapidly growing segment.

Electric vehicles: the fastest-growing per-unit consumer

An internal combustion engine (ICE) vehicle contains roughly 15 to 28 grams of silver per vehicle, mostly in switches, sensors, relays, and small electric motors. A battery electric vehicle contains substantially more because it adds high-voltage power electronics, battery management systems, on-board chargers, and dozens of additional sensors and switches.

The Silver Institute / Oxford Economics report cites a per-vehicle silver load of 25 to 50 grams for battery electric vehicles, which is 67% to 79% more silver than a comparable ICE vehicle. Plug-in hybrids sit in between. Charging infrastructure adds a further silver load per charger installed, particularly in fast-charging stations that use silicon carbide power electronics and high-current relays.

The World Silver Survey 2026 confirms that the automotive share of “other industrial” demand continues to climb, driven by both rising EV penetration and increased silver content per vehicle (more sensors and switches even in modern ICE cars for advanced driver-assistance systems). The Oxford Economics report projects that by 2031, electric vehicles will account for 59% of total silver demand from the automotive sector. That is a forecast from the Oxford Economics work and not a Silver Institute survey number; treat it as a directional projection rather than a hard estimate.

Medical and antimicrobial silver

Silver ions are naturally antimicrobial. The medical device industry uses silver in wound dressings, catheter coatings, surgical instruments, and dental restorations. Consumer products use silver in athletic apparel, food packaging films, and appliance surfaces to inhibit microbial growth. The World Silver Survey classifies this demand inside the “other industrial” line rather than as a stand-alone category, so precise segment numbers are not published, but the segment is one of the reported drivers of steady growth in the other-industrial bucket.

Nanosilver (silver in particle sizes below 100 nanometers) is the workhorse form for antimicrobial applications because the high surface-area-to-volume ratio maximizes ion release. Regulatory scrutiny (US EPA, EU REACH) is tightening around unnecessary nanosilver in consumer goods but not around demonstrably medical uses, where the clinical benefit is documented in peer-reviewed literature.

Brazing alloys, solders, and other industrial uses

Silver-bearing brazing alloys join dissimilar metals in HVAC systems, refrigeration equipment, aerospace assemblies, and power plants. Silver solders (which use lower silver content than brazing alloys) do similar work at lower temperatures. This is a mature end use with modest single-digit growth tied to global construction, aerospace production, and industrial equipment cycles.

The World Silver Survey 2025 puts brazing alloys and solders at 47.9 Moz in 2024, roughly flat with 2023. Other industrial applications (catalysts, mirrors, water purification, biocides, medical, printed electronics, and everything not otherwise classified) totaled 132.4 Moz in 2024. Photography, once a top-three industrial end use in the film era, is now a small residual line at 24.5 Moz in 2024, essentially flat and unlikely to change materially.

Why industrial demand matters for silver supply

The reason all of this matters for anyone who owns physical silver, or is thinking about buying it, is that industrial demand is largely price-inelastic in the short run. When a solar module manufacturer builds a factory, it commits to a silver-paste supply plan. When an automaker qualifies a silver-bearing sensor for a vehicle platform, it uses that part for the whole platform lifecycle. Industrial buyers do not stop buying silver when the spot price rises 20%. They pass the cost through to the finished product or absorb it into margins.

Meanwhile, mine supply is slow to respond. The World Silver Survey 2025 reports 2024 mine production of 819.7 Moz, up less than 1% year over year. The World Silver Survey 2026 shows 2025 mine production at 846.6 Moz, up 3%. Roughly 72% of that supply is a by-product of copper, lead, zinc, and gold mining, which means silver mine output is largely dictated by the economics of other metals rather than by the silver price itself. Recycled silver added 178.9 Moz in 2024 and 195 Moz in 2025 per the same WSS reports.

The result has been persistent annual deficits. Industry data from the Silver Institute and Metals Focus:

Cumulative deficit over the five years 2021 to 2025 is roughly 800 Moz. That gap has been filled by drawing down above-ground stocks (bullion held in London vaults, COMEX warehouses, and Shanghai depositories). Above-ground stocks are finite. The World Silver Survey 2025 called out that identifiable bullion inventories in London vaults declined for the third consecutive year through end-2024, and the WSS 2026 confirmed further modest drawdown through end-2025.

None of this predicts a silver price move. Precious metals prices react to a mix of industrial fundamentals, monetary conditions, investor flows, and speculative positioning, and the Silver Institute does not publish price forecasts. What the data does say is that industrial demand is structural, growing, and technology-driven, and that mine supply has struggled to grow with it. Each of those non-industrial forces is mapped out separately in what actually moves silver prices.

Where recycling fits in the industrial cycle

Recycled silver (called “silver scrap” in the WSS) is the second-largest supply source after mine production. Most silver recycling comes from three streams: industrial scrap (spent electronics assemblies, plating solutions, radiographic film), jewelry and silverware scrap sent for refining, and photovoltaic module recycling (still a small stream but growing as first-generation solar farms reach end of life).

Photovoltaic module recycling is worth watching. The Silver Institute reports that end-of-life PV recycling was a small contributor to 2025 scrap totals, but the first big wave of installed panels (systems deployed 2010 to 2015 in Germany, Italy, and Spain, plus 2013 to 2018 in China) is now reaching typical 25 to 30 year design life. The volume of end-of-life panels will grow through the late 2020s and into the 2030s. Silver recovery rates from spent panels can exceed 90% with the right process, so mature PV recycling infrastructure would eventually recycle a meaningful share of the silver installed today.

Comparing silver’s industrial profile with gold and platinum

Silver stands out among the precious metals for how much of its demand is genuinely industrial. Rough shares of total demand across the three metals in a typical recent year:

Silver shares in the table are drawn from the World Silver Survey 2025 covering 2024. Gold shares are from the World Gold Council Gold Demand Trends 2024 full-year report. Platinum shares are from the World Platinum Investment Council Platinum Quarterly Q4 2024 report. Directional comparison only, single-year snapshots move with cycles. The full breakdown of gold mine output, recycling, and demand by end use is in gold supply and demand.

The practical implication for a US investor: silver’s price behavior is a hybrid of an industrial commodity and a monetary metal. Gold trades much more like a pure monetary asset. Platinum trades much more like an industrial commodity tied to the auto cycle. Silver is meaningfully both, which explains why silver often shows higher price volatility than gold in either direction. Investors asking whether platinum belongs in a tax-advantaged account will find the eligibility rules in the platinum IRA complete guide.

Individual investor takeaways from the industrial demand data

Three practical points a US investor can draw from the WSS 2025 and WSS 2026 numbers:

• The demand base is structural, not cyclical. Solar installations, electric vehicles, data centers, and 5G build-out are policy-driven and multi-year infrastructure programs. They do not turn off in a recession the way, for example, consumer jewelry purchases might.
• Substitution risk exists but is bounded. Every major silver-consuming industry has a substitution research program (copper-plated solar cells, aluminum bond wires in some electronics, alternative antimicrobials). None of these have displaced silver at scale in the past decade. Ongoing monitoring is worthwhile but not urgent.
• Silver is a physical commodity first. Owning silver means owning a metal with a real industrial use. That is materially different from owning a fiat currency or a digital token. It is also different from owning gold, which is dominated by monetary demand. If you buy silver for portfolio diversification, understand which side of that dual nature is doing the work in your thesis.

Silver’s role inside a retirement account has its own set of rules that turn on the specific product form (round versus bar versus coin, fineness, IRS-approved refiner or mint). The Goldiew silver IRA eligible products full list covers exactly which silver products qualify under IRC Section 408(m)(3) and which do not. If you are considering a rollover or a first-time precious metals IRA setup, the silver IRA rollover step by step guide walks through the mechanics.
