Solar Power Drives Surge in Silver Demand
Industrial demand for silver, particularly from solar photovoltaic manufacturing, now accounts for nearly 60% of total global demand. The surge, reaching 680 million ounces in 2024, is rewriting the supply-demand equation for the precious metal. Miners and explorers are now racing to find new sources to support the green energy transition.
The accelerating shift to more efficient solar cell technologies is intensifying silver consumption. Newer designs like TOPCon (Tunnel Oxide Passivated Contact) and HJT (Heterojunction) can require significantly more silver than the previous industry-standard PERC cells. Key manufacturers such as JinkoSolar, LONGi, and Trina Solar are all ramping up production of these next-generation panels. This technological transition is a primary driver behind the solar industry's growing appetite for the metal, which accounted for approximately 17-19% of global silver demand in 2024. Projections indicate that photovoltaics could consume between 321 to 450 million ounces annually by 2030, a substantial increase from the estimated 198-243.7 million ounces used in 2024. The supply side of the equation faces significant constraints, keeping the market in a structural deficit for several consecutive years. The shortfall in 2024 was approximately 150 million ounces, with a deficit also projected for 2025. This persistent gap highlights the difficulty in quickly ramping up silver output. A major challenge is that over 70% of silver is mined as a byproduct of operations focused on other metals like copper, lead, and zinc. This means production levels are not solely dictated by silver's price or demand. Compounding this, miners are facing declining ore grades, meaning more rock must be processed to extract the same amount of silver. Major silver producers include Mexico's Fresnillo plc, Poland's KGHM Polska Miedź, and US-based Newmont. These companies are at the forefront of meeting the surging demand, but bringing new primary silver mines online is a lengthy and capital-intensive process. To mitigate future supply risks, the solar industry is actively researching ways to reduce silver usage through "thrifting" and the use of alternatives like silver-coated copper powders. Additionally, significant progress is being made in recycling, with new methods capable of recovering over 97% of the silver from end-of-life solar panels, promising a future "urban mine" of valuable material.
