Photoncycle raises €15 million to launch seasonal hydrogen home storage
Norway’s Photoncycle has raised €15 million ($17.4 million) to develop a seasonal home energy storage system that converts excess solar power into ammonia-based hydrogen for winter use.
London Underground inks private-wire solar deal with SSE Energy Solutions
Transport for London on track to receive 65,000 MWh of electricity per year from solar connected directly to one of Europe’s largest private power networks.
EU opens third cross-border solar tender
The EU’s third cross-border solar tender is offering a share of €54.9 million ($63.8 million) to solar-plus-storage projects in selected Bulgarian districts and ground-mounted solar projects in Finland, with funding provided by Luxembourg. The deadline for applications is September 1.
Greece faces rising renewables curtailment, driving solar-plus-storage
Greece’s solar producers are facing rising curtailments that are cutting revenues and driving interest in energy storage, even as regulatory and financing challenges slow deployment.
Germany’s Texxecure launches standardized quality rating for PV systems
The Texxecure PV Quality Rating evaluates solar modules, inverters, and entire projects using uniform technical criteria, condensing technical risk into a single AAA-to-D score for developers, investors, banks, and insurers.
Ecoflow debuts 5 kWh residential inverter battery with 100% depth of discharge
EcoFlow has unveiled the single-phase Ocean 2 all-in-one battery inverter at Key Energy in Rimini. The system features a more compact 5 kWh LFP battery stackable up to 30 kWh and offering 100% depth of discharge, 3.4 kW discharge power, and IP66 protection.
Estonia deploys 105 MW of solar in 2025
Estonia’s cumulative solar capacity reached around 1,430 MW by the end of last year. Year-on-year installations slowed as the country’s solar market begins to saturate, with future growth expected to be driven by supplementing solar parks with batteries.
CEA-Ines, 3Sun build heterojunction solar modules based on UV downshifting
The new heterojunction solar module concept is based on co-extruded EVA/POE/EVA (EPE) encapsulant with UV downshifting (UV-DS) films, which convert harmful UV light into blue light, protecting cells and slightly boosting short-circuit current by 1.5–1.75%.
Hybrid perovskite solar cell generates power from sun and rain
Researchers at ICMS in Seville have developed a hybrid perovskite solar cell that generates electricity from both sunlight and raindrops, using the photovoltaic and triboelectric effects. A fluorinated CFₓ polymer layer enables water resistance, triboelectric energy harvesting, and high light transparency without reducing solar cell efficiency.
UK government issues open call for experts to shape AI energy policy
