China’s SDIC subsidiary commissioned a 1 GW photovoltaic plant on the Yalong River in Sichuan, making it the world’s third-highest-altitude PV facility at 4,600 m. The project integrates with hydro assets to optimize energy output in the challenging plateau environment.

The U.S. Department of Energy moved to de-obligate or revise billions in financing for clean energy projects while prioritizing natural gas and nuclear power.

This week Women in Solar+ Europe gives voice to Melodie de l’Epine, Senior Project Manager/ Head of Research & Innovation at France’s Becquerel Institute. She says that ncouraging men to shift from strict hierarchy to informal exchanges fosters more equitable rapport. Women can benefit from noticing how men address each other and consciously joining in, since subtle forms of address strongly shape power perceptions.

In a new weekly update for pv magazine, Solcast, a DNV company, reveales that last year extreme Canadian wildfires drove aerosol levels around 30% above normal, sharply reducing solar irradiance across Canada and even impacting Europe, while the Congo Basin also saw worsening aerosol conditions. In contrast, China and South America experienced unusually low aerosol levels, supporting stronger solar irradiance due to cleaner air, reduced fires, and favorable climate and policy conditions.

In all ages, humankind decided to spend considerable amounts of the available productivity on special monumental projects. Managing climate change and rebalancing within the planetary boundaries is such an activity. The enormous energetic productivity of solar PV may evolve as the central pillar to create a sustainable civilization.

Conceived for stationary energy storage, the proposed sodium-ion battery configuration relies on an P2-type cathode material and an hard carbon anode material that reportedly ensure full-cell performance. Electrochemical testing revealed initial capacities of 200 mAh/g for the cathode and 360 mAh/g for the anode with capacity retentions of 42% and 67.4% after 100 cycles.

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.

Austrian engineering group Andritz has signed a deal to supply the pump turbine units for a 500 MW pumped storage plant in South Korea, the country’s first new pumped storage project in over a decade.

Spanish tracker manufacturer Solar Steel has introduced an upgraded 2P single-row tracker designed to simplify assembly, improve standardization, and support deployment on complex terrain, including agrivoltaic projects.

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.
