A solar cell with thinning silver gridlines beside a widening supply deficit bar

Where things stand

Written 11 September 2026, on Silver Institute forecasts for 2026 and contemporaneous analysis of solar silver loadings.

Solar took 19 per cent less silver in 2026 than in 2025 — photovoltaic demand falling from around 186.6 million ounces to roughly 151 million, the largest annual decline on record in silver’s biggest industrial end market.

The silver deficit widened anyway. The market is running a sixth consecutive annual shortfall, and forecasts put 2026 wider than 2025 rather than narrower.

Thrifting, not substitution

The distinction matters and is routinely lost. Solar manufacturers have not replaced silver. They have learned to use less of it per cell — finer gridlines, better screens, different cell architectures — which is what the industry calls thrifting.

That is a durable, engineering-driven reduction in grams per watt. It is not silver being designed out. Every cell still needs it, and the industry is still installing more gigawatts each year, so the total is falling more slowly than the per-cell figure suggests and will stop falling when thrifting hits its physical floor.

Why the deficit widened despite the fall

Because industrial demand is not the whole market. Physical investment demand — coins, bars, exchange-traded products — is forecast up sharply to a multi-year high, and that increase more than absorbed the tonnage solar released.

  • Industrial pullback: solar thrifting, and jewellery and silverware fabricators cutting content at high prices
  • Investment inflow: retail and institutional buying of physical metal, which is price-chasing rather than price-sensitive
  • Mine supply: largely a by-product of copper, lead and zinc mining, so it does not respond quickly to a silver price signal

The by-product problem. Most silver is not mined for silver. It comes out alongside base metals, which means the supply response to a high silver price is weak — the operator’s decision is driven by copper or zinc economics. A deficit can therefore persist for years rather than self-correcting.

What it means for solar cost in India

Directionally, less than the price chart implies. Silver is a small share of a module and a smaller share of an installed system, and thrifting has been cutting the exposure at roughly the rate the price has been rising.

The more useful reading is about module prices generally, which are in a different cycle: polysilicon oversupply has held module pricing near historic lows through 2026 regardless of what silver does. A metal getting dearer inside a component whose price is being set by a glut elsewhere in its own supply chain does not move the number a buyer sees.

For anyone sizing a rooftop or a solar-plus-storage system, module price is not currently the variable to worry about. Our note on sizing solar and storage for an Indian home covers the ones that are.

The caveat

Forecasts of structural deficits have a poor record of predicting prices. A deficit tells you the flow balance, not the stock — there are large above-ground inventories, and what they do is decided by investors rather than by manufacturers. Analysts warning of volatility rather than a steady climb are describing the honest position.

Frequently asked questions

What is silver thrifting in solar cells?+

Using less silver per cell rather than replacing it — finer gridlines, better screen printing and different cell architectures. It is a durable engineering reduction in grams per watt, not silver being designed out. Every cell still needs it, so total demand falls more slowly than the per-cell figure implies and will stop falling once thrifting reaches its physical floor.

Why did the silver deficit widen if solar used less?+

Because industrial demand is not the whole market. Physical investment demand — coins, bars and exchange-traded products — rose to a multi-year high and more than absorbed the tonnage solar released. Mine supply could not respond, because most silver is a by-product of copper, lead and zinc mining.

Does a higher silver price make solar more expensive in India?+

Not noticeably right now. Silver is a small share of a module and smaller still of an installed system, and thrifting has been cutting that exposure at roughly the rate the price has risen. Module prices are currently being set by polysilicon oversupply, which has held them near historic lows regardless of silver.
