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.

A record surge in solar generation met 75% of global electricity demand growth in 2025, according to the latest Global Electricity Review 2026 from energy think tank Ember. According to the report, renewables accounted for 33.8% of global power generation in 2025, surpassing one-third for the first time and overtaking coal in a milestone moment for the energy transition. The structural shift in the global power energy mix contributed to a small decline in fossil fuel generation of 38TWh. Solar generation rose by 636TWh in 2025, marking the largest increase of any power source on record outside coal’s post-pandemic rebound in 2021. The scale of growth was equivalent to twice the annual electricity demand of the UK. Solar’s upward trajectory has continued to accelerate, with generation increases rising from 331TWh in 2023 to 479TWh in 2024, before reaching a record level in 2025. Global solar generation reached 2,778TWh in 2025, overtaking wind for the first time and cementing its position as the fastest-growing electricity source globally. The expansion in generation was supported by another record year for installations, with 647GW of solar capacity added globally in 2025, an 11% year-on-year increase. According to Ember, this sustained pace of deployment reflects long-term cost reductions, with solar panel prices falling by 90% between 2015 and 2024. Larger economies have also leaned heavily on solar-led clean power growth. China recorded the largest increase in electricity demand over the period, rising by an average of 513TWh annually, with 76% of this growth met by clean sources, led by solar. In the US, clean power supplied 88% of new demand, with solar forming a key component of that expansion. In India, which saw the second-largest increase in demand at 101TWh per year, clean energy met 48% of additional demand, a significant rise from 24% in the previous decade.   China and India lead the way A key driver of the global shift was the significant simultaneous decline in fossil generation in China and India. China’s fossil generation fell by 56TWh, while India recorded a decline of 52TWh. The two countries accounted for 42% of global fossil fuel generation in 2025. In China, the fall came despite strong electricity demand growth of 503TWh, as clean generation expanded more rapidly, increasing by 15% to 561TWh. Solar was the primary contributor in the country, rising by 40% to 336TWh. Solar alone met two-thirds of the country’s demand growth. China continued to dominate global capacity deployment, installing 378GWdc of solar in 2025, equivalent to 58% of global additions. In India, a surge in renewable generation coincided with relatively modest demand growth of 49TWh, the third-lowest increase in the past decade. Renewable output rose by a record 24% to 98TWh, driven by strong gains in solar and wind. However, milder weather conditions reduced electricity demand by an estimated 32TWh compared to 2024.   Emer...

Policymakers should accelerate the deployment of renewables to capitalise on the low costs of these technologies and insulate national grids from power price fluctuations caused by global energy disruptions.   These are the main recommendations from the latest policy advisory document from the International Renewable Energy Agency (IRENA). ‘From Energy Crisis to Energy Security: Actions for Policy Makers’ uses the ongoing conflict in the Middle East as an example of how geopolitical and global supply chain disruptions can impact fossil fuel power prices and the economies that are reliant on these technologies.   For instance, IRENA estimates that new solar PV and wind additions across the EU has reduced the demand for fossil fuels from areas in the Middle East that have been impacted by the conflict, saving the bloc €58 billion (US$67.8 billion) in additional fuel costs that would have had to be paid to import fossil fuels amid the conflict.   This echoes a similar conclusion drawn by trade body SolarPower Europe earlier this month, which found that Europe’s domestic solar capacity has saved EU countries over US$127.5 million a day since the start of the war by minimising the demand for fossil fuels.   The strategic case for renewables The IRENA document makes a number of policy recommendations to facilitate further renewable energy deployment with this economic background in mind, split over short- (up to six months), medium- (up to one year) and long-term (up to three years) timeframes.   The short-term recommendations include deploying distributed renewable energy projects alongside solar-plus-storage projects for off-grid use, as these systems are much faster to deploy than utility-scale projects or traditional grid expansion work, and introducing “grants, subsidies or tax rebates” to make renewable energy a more compelling investment option.   Heard earlier this year from SolarPower Europe about financial mechanisms, such as government auctions, and the role they have to play in making solar an attractive investment case for would-be financiers.   IRENA’s medium-term recommendations include fast-tracking current renewable energy and grid infrastructure projects, alongside incentivising battery energy storage system (BESS) deployments to improve overall grid resilience. The long-term recommendations include developing supportive policy frameworks to encourage renewable energy deployments in the long-term and supporting domestic and regional energy supply chains to minimise reliance on volatile global power prices.   “The current crisis clearly demonstrates the strategic case for renewables as a national security imperative”, said IRENA director-general Francesco La Camera. “There is an opportunity to prioritise actions that enhance long-term energy stability.   “Governments must urgently consider targeted interventions to steer invest...
