The largest single-unit rooftop solar power plant in Europe, developed by French independent power producer Urbasolar, is under construction on the Delta 3 multimodal logistics platform in Dourges, in France’s Hauts-de-France region.

During testing at Estonia’s 100 MW Kiisa battery park, both EstLink 1 and EstLink 2 tripped, triggering the most severe disturbance to the regional power grid since desynchronization from the Russian electricity system. As a result, nearly 1 GW of capacity was lost within seconds. The park’s owner has since publicly pointed to the battery manufacturer.

The Dutch start-up, founded by former Tesla leaders, is taking a novel approach to sodium-ion battery technology, optimizing it for integration with solar power plants. Its technology is set to be deployed for the first time in a Dutch solar-plus-storage project later this year.

Envision Energy has launched a fully integrated energy storage solution combining hardware, software, and market-facing AI to optimize performance, safety, and trading. Its “Physical AI” platform embeds intelligence across cells, systems, and operations, enabling predictive maintenance and real-time market participation.

Deployment hits ten year high in the United Kingdom with connection of largest plant to date and a ramping up of small-scale installations. Government targets accelerated deployment with new support for rooftop installations and ongoing CfD auction.

Silver hit a new all-time high of $117.66/oz, climbing over 40% in the past month and 275% in the past year, driven by dollar weakness, geopolitical tensions, and gold’s strong momentum. Silver analyst Matthew Piggott tells pv magazine the metal may reach $130/oz within a couple of weeks.

Iberdrola has commissioned Spain’s first utility-scale batteries at Alarcón, while Spain’s battery pipeline grows as major utilities develop new projects amid negative electricity prices.

The Ariya demonstration vehicle features 3.8 m² of Lightyear’s custom solar panels integrated across the hood, roof, and tailgate. Testing showed that the car could generate 0.5 kWh of solar energy during a 2‑hour, 80 kilometer trip, delivering up to 3 kilometers of range at no extra cost or charging time.

Rooftop solar generation reached 4,407 MW in Australia’s National Electricity Market (NEM) in the fourth quarter of 2025, contributing to peak renewable supply of 78.6% and reducing daytime operational demand.

GIST researchers have developed a perovskite mini-module with 22.56% efficiency by improving the SnO₂ electron transport layer with PEI, reducing defects and electron loss. The module retained 94% of its performance after 500 hours, highlighting potential for scalable, stable perovskite solar cells and modules.
