Commodity Trading Club (CTC) says Mexico, Peru, Bolivia, Chile and Argentina together supply more than half of the world’s silver production, a keystone metal for the solar energy and clean technology industries. November 6, 2025 Luis Ini Silver metallization paste Image: Heraeus By pv magazine LatAm Latin America now anchors the global silver supply chain, producing more than 55% of total world production. The metal – essential for the production of solar panels, semiconductors and electric vehicles – has shifted decisively from its historic monetary role to an industrial role. According to CTC, Mexico leads with annual production of 185.7…

German industrial group Bosch says the Bamberg plant meets European Union rules for renewable hydrogen and will produce more than a tonne of green hydrogen every day. November 6, 2025 Sandra Enkhardt The green hydrogen is stored in the 21 meter high tank under a pressure of up to 50 bar Image: Bosch By pv magazine Germany German manufacturer Bosch has put its first self-operating hydrogen electrolyzer, consisting of two proton exchange membrane (PEM) electrolysis stacks with a combined power of 2.5 MW, into operation at its Bamberg site in southern Germany. Bosch said the new in-house system produces renewable…

Major milestone for solar deployment in Britain as 15 CfD-backed projects start in the first three quarters of 2025. Further utility-scale deployment is expected, but much will depend on the outcomes in the next two CfD allocation rounds. November 5, 2025 Matthew Lynas Cleve Hill is the largest UK solar power plant commissioned to date and one of fifteen CfD-backed projects due to come online in 2025. Image: Quinbrook According to the latest government figures, Britain has broken the 20 GW barrier for solar energy deployed, adding 1.4 GW since the start of 2025, including 106 MW in September. The…

Clearway Energy Group has announced that its Rosamond South 1 project in Kern County, California, is commercially operational. The 117 MW energy storage and 140 MW solar complex will generate enough electricity to power more than 72,000 homes annually, deploying low-cost energy during peak demand when it is needed most. “We are pleased to bring Rosamond South online and continue to serve Kern County and the broader region with reliable, low-cost energy,” said Valerie Wooley, senior VP of origination at Clearway. “Thank you to our valued customers for partnering with Clearway to help achieve your clean energy goals and bring…

Researchers in Spain assessed six models used to calculate angle of incidence modifier (IAM) losses in photovoltaic systems. They identified the Martín-Ruiz model as the most comprehensive, as it uniquely accounts for additional angular losses caused by contamination. November 5, 2025 Emiliano Bellini Researchers from the Technical University of Madrid have completed a comprehensive review of modeling tools used to measure the angle of incidence modifier (IAM) – a factor that describes how the optical efficiency of photovoltaic (PV) modules changes as the sun’s rays deviate from a line perpendicular to the module surface. The team explained that IAM losses…
