On May 25th, international oil prices plummeted, while precious metals surged. Spot gold broke through $4570/ounce, rising over 1% intraday. Spot silver touched $78/ounce, rising over 4%. Since 2026, the silver market has experienced a rollercoaster ride: after surging to historical highs at the beginning of the year, it has sharply corrected and is currently maintaining a wide range of high-level fluctuations. As the largest industrial demand sector for silver, photovoltaics is seeing increased silver consumption per unit due to rising penetration rates of high-efficiency cells (TOPCon/HJT/BC). The soaring silver price has become a core pressure on the cost of solar panels.   Silver prices are under pressure due to high-level fluctuations. At the beginning of the year, silver continued its upward trend from 2025, strongly rising due to the triple positive factors of expectations of a Fed rate cut, Middle East geopolitical conflicts, and the essential demand for photovoltaics. In late January, London silver broke through $100/ounce, reaching a nominal historical high of $121/ounce on February 28th. Domestically, the main Shanghai silver futures contract surged in tandem, reaching over 22,000 yuan/kg in mid-April, a quarterly increase of over 60%. In late May, silver prices entered a trading range of $70-85/ounce (London silver) and 17,000-20,000 yuan/kg (Shanghai silver). Institutions predict a "mild decline with wide fluctuations" in the second half of the year: on the one hand, the peak season for global photovoltaic installations in Q3-Q4 will support industrial demand, and a silver supply-demand gap will persist (approximately 60 million ounces in 2026); on the other hand, the accelerated implementation of "de-silvering" technologies, high prices suppressing jewelry demand, coupled with uncertainty surrounding Federal Reserve policies, have weakened silver price rebounds, and prices may fall back to around $70/ounce by the end of the year.   N-type penetration drives up unit silver consumption; photovoltaics becomes the largest industrial demand for silver. Photovoltaics has become the largest industrial demand sector for silver. In 2025, photovoltaic silver consumption accounted for 35% of global industrial silver consumption. Although the "de-silvering" trend accelerated in 2026, the expansion of installed capacity still drove demand to remain high. Comparing the silver consumption of mainstream battery technologies, the penetration rate of N-type high-efficiency batteries, represented by TOPCon/HJT, is rapidly increasing, reaching 70% by the end of 2026, directly driving up the unit silver consumption: Previously, PERC had a silver consumption of 8.5-9.5 mg/W per watt, with a single cell consuming approximately 70 mg of silver; the technology was mature and had the lowest silver consumption. Specifically, TOPCon (N-type, currently the mainstream high-efficiency battery): using a double-sided silver paste process, has a silver con...

  New solar PV installations in China have reached 50.9GW between January and April 2026, according to data from the Chinese National Energy Administration (NEA).   The figures indicate that new PV capacity additions tumbled markedly over the period, while wind power maintained steady growth. Installation figures for the first four months of 2026 represent a 51% drop compared to the 104.93GW registered in the same period of 2025.   Ongoing adjustments continue to drive structural improvements across the country’s power installation mix.   Sharp drop in new PV capacity, April monthly slump most striking   Monthly breakdowns reveal an even steeper downward trajectory. New PV installations stood at merely 9.52GW in April 2026, plummeting 79% year-on-year versus 45.28GW a year earlier. The slowdown carries forward the weak growth momentum seen in the first quarter.   In contrast to the PV installation slump, wind power capacity posted steady growth. China added 21.26GW of new wind capacity from January to April 2026, rising 7% from 19.96GW in the same period last year.   As of the end of April 2026, China’s total installed power generation capacity reached 3,990GW, growing 14.2% year-on-year. The proportion of new energy capacity kept climbing. Solar installed capacity hit 1,250GW, a 26.2% year-on-year rise, and wind power capacity stood at 660GW, up 22.0% year-on-year.   Industry analysts attribute the sharp drop in new PV installations in the first four months to a periodic adjustment after the sector’s robust growth in 2025. The downturn is driven by falling PV module prices, prevalent wait-and-see sentiment and constrained power grid consumption. By contrast, wind power registers solid development thanks to mature technologies and stable power pricing policies.
