China’s Top Solar Maker Switches From Silver to Copper
China’s largest solar manufacturer has started producing cells that replace silver with copper, responding to surging silver prices that have pressured the solar industry since last year.
China’s largest solar manufacturer has begun producing photovoltaic cells that replace silver with copper, a major shift driven by the surge in silver prices that has rattled the solar industry since last year. The move marks a significant technological pivot for the world’s biggest solar producer, which consumes vast quantities of silver in cell metallization.
For commodities traders, this development carries dual implications. Silver demand from the solar sector has been a key driver of the metal’s rally, accounting for roughly 15% of global industrial silver consumption. A widespread switch to copper could structurally reduce silver demand growth, potentially capping price upside. Conversely, copper demand could receive a boost from the solar industry, adding to existing tailwinds from electrification and grid infrastructure.

Looking ahead, the key question is how quickly other solar manufacturers adopt copper metallization. If the technology proves cost-effective and scalable, the shift could accelerate, reshaping supply-demand balances in both metals. Traders should watch for announcements from other major Chinese solar firms and monitor silver inventory data from exchanges like the Shanghai Futures Exchange.
