Researchers in Japan have adopted a new calcium-doping strategy to improve the stability and electrochemical properties of NFM, a cathode material used in sodium-ion batteries. The new technique enhances crystallinity and increases the interlayer spacing in NFM, resulting in higher performance compared to NFM treated with conventional processes.

Researchers in China have developed a dust monitoring technique that relies solely on the existing hardware resources of inverters, without requiring extra sensors or meteorological data. Tests on real rooftop PV arrays demonstrated an accuracy exceeding 96%.”

Anker Solix has introduced the 2 kWh C2000 Gen 2 portable power station, featuring faster dual-input charging, lithium iron phosphate batteries, and an idle power draw below 10 W.

The Chinese manufacturer said its new inverters can deliver 160% overload for 200 ms in off-grid mode, ensuring stable startup of heavy loads. The IP66-rated products feature a maximum efficiency of 97.6% and a European efficiency of 97.2%.

Demand for copper, often considered as one of the most valuable alternatives to silver in solar manufacturing, is expected to increase by almost a quarter globally by the middle of next decade. Wood Mackenzie says the energy transition is one of four ‘disruptors’ that could cause demand to increase further.

Carbon markets operate on trust: stakeholders must believe that the emission reductions credited are real, measurable, and permanent. Inconsistent methodologies, poorly monitored projects, and a lack of transparency have undermined confidence in certain markets. As discussions advance at COP30 in Belém, establishing universally accepted standards and accountability frameworks will be essential.

Sinn Power has deployed a 1.8 MW vertical solar array on a quarry lake in the Bavarian municipality of Gilching. The company highlights the ecological benefits of the vertical system configuration and, perhaps surprisingly, its high resistance to storms.

ArcelorMittal has started producing its Helioroof building-integrated PV modules in France. The steelmaker says the system aims to simplify energy retrofits for commercial and industrial roofs.

The new Fusio floating structure features a triangular design and is said to be particularly suited to markets such as India and Southeast Asia. Tilt angles can be configured at either 5° or 12°.

Industry players speak to pv magazine about whether China’s decision to tighten export controls on key minerals and technologies for lithium batteries will cause a short-term disruption or lead to a long-term strategic realignment of the global supply chain.
