China’s Solar Shift: Copper Cells Threaten 19% of Silver PV Demand in 2026
Key Takeaways
- Major Chinese solar firms are ditching silver for copper in PV cells—could cut PV silver demand by 19%.
- This is the first time all three market leaders are mass-producing copper-based cells at scale.
- Silver’s six-year deficit story may face a new test if the copper transition accelerates globally.
- I’ll be watching silver demand data closely—this could shift portfolio strategies for Singapore buyers.
Chinese Solar Giants Pivot Away from Silver
The structural shake-up comes as China’s top three solar manufacturers—LONGi Green Energy, JinkoSolar, and Aiko Solar—begin mass production of copper-based cells this quarter. Traditionally, silver has been a critical component in solar PV cells, used to carry electricity generated by sunlight. But copper, which is much cheaper, now threatens to displace silver on a scale not seen before.
Analysts estimate the change could reduce global silver demand for solar by up to 19% in the coming years, should the switch be sustained and adopted outside China. That’s a significant dent—solar accounted for an estimated 14% of total silver demand last year. The move comes as producers face ongoing margin pressure and seek ways to control costs in a fiercely competitive market.
Here’s a quick comparison of key numbers:
| Metric | 2025 Value | Post-Copper Estimate |
|---|---|---|
| Silver demand (solar, Moz) | [Undisclosed] | -19% |
| Solar’s share of total demand | ~14% | Lower (uncertain) |
| Number of firms adopting tech | 3 (top Chinese) | Likely to grow |
As someone who’s been tracking silver’s industrial growth—especially in clean energy—this is the first time I’ve seen all three leaders synchronise a technology pivot like this. It’s not just an R&D experiment lah, but full-scale production. That’s bound to ripple through the entire PV supply chain and, by extension, the silver market.
For context, solar demand helped drive silver’s six-year deficit streak, with Singapore buyers often looking to solar as a bullish thesis. You can read more background in our previous report on silver’s 2026 deficit and our main silver products page.
What This Means for Silver Prices and Investors
So, what now for silver prices? The short-term reaction looks muted—global investment demand and AI-related industrial use are still running hot. But if copper-based PV cells catch on outside China, we could see a material dent in the “solar demand” narrative that’s propped up silver for years. It’s a structural headwind, not a short-term blip.
For Singapore investors, this means it’s time to be a bit more tactical. Do you double down on silver’s long-term tech potential, or rebalance in favour of gold or even platinum? I’m personally watching for updated demand numbers before making any allocation moves—timing matters more than ever now. If you’re thinking of adding or trimming, my usual approach is to shop around at reputable local dealers like BullionStar.
Of course, this doesn’t erase silver’s other demand drivers. But it does mean the “solar supercycle” thesis is due for a reality check. For a broader portfolio context, see my breakdown of 2026 Singapore bullion strategies.
