RWE drops 99.9 MW solar project in Wales on grid constraints
RWE has scrapped its 99.9 MW Butterfly solar‑plus‑storage project in Wales after determining that grid connection availability made it unviable, in a move that comes amid sharply rising connection demand and mounting pressure on the United Kingdom’s queue reform process.
Span and Nvidia to develop AI data centers in your backyard, lowering electric bills
The two companies will develop XFRA, a distributed network of compute nodes connected to homes with smart panels, batteries and optional solar generation, in partnership with Nvidia and homebuilders like PulteGroup,
Silver demand from PV industry expected to drop 19% this year
A new report from Metal Focus reveals that global silver market remains structurally tight, with elevated prices, a fifth consecutive annual supply deficit in 2025, and ongoing mine and recycling constraints despite modest production growth. At the same time, PV-driven silver demand is falling sharply due to cost pressure and thrifting.
European power grid investment set to rise sharply by 2027
The EU Agency for the Cooperation of Energy Regulators (ACER) says distribution grid investment has risen 51% since 2021, but warns that fragmented planning rules and regulatory distortions could limit efficiency and slow the energy transition.
Togo opens solar minigrid tender
The government of Togo is running a tender for the construction of solar minigrids in 27 rural localities. The deadline for applications is May 26.
Varta launches all-in-one residential inverter and modular battery
The German manufacturer has launched an integrated energy system combining inverter, storage and energy management in a modular, scalable solution for new and existing PV installations. The system supports AC/DC coupling, backup power and smart energy optimization.
France, Germany set daily solar records for April
AleaSoft Energy Forecasting’s latest analysis finds increased solar energy production and lower gas futures prices helped reduce electricity prices in most major European markets last week. Germany produced 426 GWh of solar on April 8, a record for a day in April. France also set a new April day record a day later, generating 136 GWh.
Porous silica-based anti-reflective coating increases PV glass optical transmission by 5.2%
Researchers in Spain developed a porous silica anti-reflective coating for solar panels that boosts optical transmission while balancing durability and mechanical stability through optimized sol–gel chemistry.
Cyber threats for PV: What are credential compromise attacks and how do they work
Credential compromise attacks allow adversaries to gain unauthorized access to PV systems by stealing or guessing valid login credentials, enabling them to manipulate operations, disrupt monitoring, or take control of critical assets. These attacks can lead to operational instability, reduced energy production, and safety risks, making strong authentication and access control essential for system resilience.
Free midday electricity key to drive consumer demand to match excess PV generation
Free midday electricity schemes aim to shift household demand into periods of high solar PV generation, reducing midday surplus and evening fossil-fuel ramp-up. Research on Australia’s Solar Sharer program suggests such incentives could significantly improve renewable utilization, but outcomes depend on consumer behaviour, load shifting, and rebound effects.
