With silver prices rising, more large solar manufacturers are expected to switch to copper for cell metallization. Radovan Kopecek of ISC Konstanz tells pv magazine that he expects the entire industry to follow. Ning Song of the University of New South Wales says a small efficiency tradeoff may be acceptable if the cost savings are significant and do not introduce new reliability risks.

Chinese manufacturer Sungrow has introduced a new utility string inverter, a three-phase hybrid inverter for commercial and industrial (C&I) applications, and a liquid-cooled energy storage system.

Scientists have conducted a six-sphere literature analysis of agrivoltaics, considering sustainability, soil–crop productivity, socioeconomic resilience, solar power generation, spatial efficiency, and species. They found that, under optimal terms, agrivoltaics may generate over $1 trillion in added global agricultural income.

The Chinese firm has unveiled its latest energy storage solution, the ENERpro-LFP48300, equipped with a 48V, 300 Ah lithium battery. The company boasts a lifespan of over 9,500 cycles at a high 95% depth of discharge.

Rising silver prices are pushing PV manufacturers toward copper-based metallization, with DK Electronic Materials targeting 2026 for large-scale deployment of high-copper paste solutions, while Fraunhofer ISE warns efficiency trade-offs remain unacceptable.

Researchers in Spain have tested the erosion resistance of common galvanized coatings using both free-falling sand and forced-air sand-impingement methods. The study found that continuously galvanized steel coatings showed the lowest erosion rates, outperforming HDG and Zn-Al-Mg coatings.

A research group from the European Commission Joint Research Centre has developed a new PV climatic classification, the first to address annual yield and performance ratio. Their work resulted in 10 globally applicable clusters. “It challenges the assumption that many more classes are needed to capture PV-relevant climate,” the researchers said.

US-based Copeland has launched its Sensi Hydro sanitary water heat pump designed to provide energy-efficient hot water for hotels, commercial buildings, and public facilities. The units feature ZW scroll compressors, independent refrigerant circuits, and backup mode to ensure reliable hot water supply.

UNSW researchers found that some POE encapsulants can trigger severe corrosion in TOPCon solar modules, causing up to 55% power loss under damp-heat conditions. Their study highlights that module reliability depends on the exact encapsulant formulation, not just the polymer type.

A team of scientists has simulated covering 20% of the Qush-Tepa irrigation canal with PV panels. To this end, the researchers developed a framework, termed an integrated techno-economic-environmental assessment, that can be applied elsewhere. “It explicitly quantifies energy production, water-evaporation reduction, land-use savings, and economic performance within a single analytical structure,” one of the researchers said.
