Following reports of fraudulent solar inspections, Poland’s energy regulator has issued an announcement clarifying who is authorized to conduct such assessments. 

Researchers at Fraunhofer ISE have developed a perovskite-silicon tandem solar cell using a TOPCon bottom cell with standard textured front surfaces. Their results show that TOPCon bottom cells can perform comparably to heterojunction cells in tandem devices in terms of shunt resistivity, supporting scalable, cost-effective industrial production.

Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has started accepting submissions for new road-surface PV technologies, with field verification planned in pedestrian areas at roadside stations to test performance and electricity use ahead of societal implementation.

Grid operator Fluvius says that 80% of all homes, apartments and small businesses in the Belgian region of Flanders, including 89% of all solar panel owners, have now converted to digital meters as the company begins the final phase of the mandatory switch over.

AirWater and Suichoku Solar K. K. have launched a 178 kW vertical PV system at a Tottori parking lot, operating under an on-site PPA. The Verpa-based system, a first for the San’in region, maximizes space, avoids snow damage, and reportedly delivers power equivalent to rooftop solar installations.

State-owned generator Stanwell and Quinbrook Infrastructure Partners signed memorandums of understanding to deliver a 780 MW / 6,240 MWh CATL battery energy storage system integrated with 1,080 MW of gas turbines at the Gladstone State Development Area in Queensland, Australia.

Australian installer MyEnergy Engineering says its 200 kW/280 kWh hybrid microgrid in remote William Creek, South Australia, won a national 2025 award for systems over AUD 1 million ($661,200), after overcoming extreme heat, distance, and off-grid engineering constraints.

Researchers in the United States found that shading from agrivoltaic systems reduces grain numbers in both sorghum and soybean, but sorghum can partially compensate by increasing grain weight while soybean cannot. The study shows that sorghum and soybean respond differently due to their physiology, offering guidance for crop selection and management to minimize yield penalties in agrivoltaics.

Chinese module manufacturer Longi says its Hi-MO 9 series with HPBC 2.0 cells achieved watt-for-watt power gains of 1.21% to 3.92% in real-world tests across multiple countries and climates, lowering the levelized cost of electricity (LCOE) compared with mainstream tunnel-oxide passivated contact (TOPCon) modules.

EcoFlow, Tibber, and Fenecon have introduced new software and hardware updates to improve residential battery control, interoperability, and grid arbitrage across Europe.
