Key takeaways from Solar Energy Expo in Poland
Solar Energy Expo 2026, Poland’s flagship PV-plus-storage trade fair, returned this month with a small show-floor footprint but a sharp focus on flexibility and market reform, as well as the storage, inverter and grid-forming technologies shaping the nation’s next phase of grid integration.
EU opens probe into Bulgaria compensation award to foreign investor
The European Commission has launched an in-depth investigation to assess whether a €61 million ($71.6 million) arbitration award in favor of Malta-based ACF Renewable Energy is compatible with EU State aid rules.
India commissions first merchant battery energy storage system
Juniper Green Energy has fully commissioned a 100 MWh merchant battery energy storage system in western India, marking the nation’s first operational project of its kind.
Chinese PV Industry Brief: Longi, Tongwei announce losses for fiscal 2025
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 Hydrogen Stream: EU Commission invites offtakers under Hydrogen Mechanism
The European Commission is advancing market matching for renewable and low-carbon hydrogen by inviting European offtakers to signal supply interest under the Hydrogen Mechanism, while Germany’s electrolysis rollout continues to lag official targets despite new EU-backed funding schemes.
U.S. government cuts $83 billion in loans, reversing energy transition funding
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.
‘I would encourage women to be attentive to how men address each other’
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.
Aerosol divide in 2025 brings clearer skies to China and smoke to Europe
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.
Solar PV will have a major role in marshalling our productivity to create a sustainable civilization
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.
Scientists design low-cost sodium-ion battery with cheap electrode materials
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.
