Solar Power

Space-based solar could power AI more efficiently than on Earth, with full-scale deployment possible in two to three years, Elon Musk said last week in Davos, Switzerland. SpaceX’s Starship launch vehicle and its reusable rockets aim to sharply reduce space access costs, enabling solar-powered AI satellites and potentially large-scale extraterrestrial energy infrastructure.

Researchers in Spain developed a new model incorporating dynamic shading conditions in Madrid to evaluate the yield and test control algorithms for vehicle-integrated PV (VIPV) systems.

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.

A more than 15% increase in silver prices over the past week is adding cost pressure to the solar supply chain, as silver paste costs currently represent around 30% of total PV module costs.

Longi, and Tongwei have predicted steep losses for fully fiscal year 2025, as persistent oversupply and falling solar module prices continue to pressure margins across China’s PV manufacturing sector.

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.
