The electricity grid is a real bottleneck for energy in the United States, and it’s not only utilities and grid operators who are struggling. Grid congestion also puts pressure on renewable energy project owners and is as much a business problem as it is a technical one, writes Alon Mashkovich, CEO of energy management business software supplier enSights.

Malaysia’s rising power demand, driven by industrial growth and data centers, is exposing grid and capacity constraints, prompting policies like Corporate Renewable Energy Supply Scheme (CRESS) to enable corporate renewable procurement while maintaining system cost recovery.

Australia’s rooftop solar market has bounced back into record-setting territory with 281 MW of new capacity registered across the country last month, marking the largest February total on record.

Researchers from Nanchang University and Trina Solar found that TOPCon solar modules exhibit metastable “degradation–recovery” under UV exposure, with light soaking fully restoring performance and no impact on real-world energy yield. Their findings highlight the need to refine UV testing standards to better reflect field performance and guide PV reliability assessments.

Canadian researchers proposed a laminate-free solar module using polycarbonate instead of EVA and glass. The new encapsulation technique reportedly enables easy disassembly, reuse of solar cells, and open-source local manufacturing.

TU Berlin researchers say early demand for round-the-clock carbon-free electricity could help bring advanced energy technologies to market faster through technology learning effects. Grant funding for the research was provided by Google, which has since announced plans to build the world’s largest iron-air battery.

In an interview with pv magazine, Empa scientist Mirjana Dimitrievska explains that the CIGS photovoltaic technology, while promising for efficiency and flexible applications, faces persistent challenges in scaling lab-level performance to cost-effective, high-throughput industrial production, limiting its ability to compete with crystalline silicon. She also emphasizes that long-term stability, reliability, and material sustainability, rather than peak efficiency, are crucial for commercial viability, especially in niche markets like building-integrated and lightweight PV.

Researchers tested a solar PV-powered system to gasify dried cattle dung, achieving higher energy recovery than grid-powered setups.Their techno-economic-environmental analysis shows the approach can cut emissions and be economically viable, though system utilization and operational factors strongly affect profitability.

Swedish thin-film solar manufacturer Midsummer has secured its largest-ever order for production equipment, covering a complete solar cell factory. It follows an initial order in May 2025 for a 15 MW line producing thin-film copper, indium, gallium and selenide (CIGS) solar cells.

Qcells says it has resumed solar panel production at its Georgia manufacturing facilities after US Customs and Border Protection released seven solar cell shipments from South Korea that had been held under the Uyghur Forced Labor Prevention Act (UFLPA), forcing a furlough of 1,000 workers and temporarily halting output at the second-largest module factory in the United States.

Researchers in Sweden have developed an air-based photovoltaic-thermal system that can preheat ventilation air and domestic hot water, cutting district heating demand by up to 16% for ventilation and 7% for hot water while also reducing peak heating loads in cold Nordic climates.

Freight costs from the Far East to the U.S. and Europe have increased week-on-week, while almost 150 container ships currently unable to leave the Arabian Gulf due to the risk of sailing through an active conflict zone, according to analysis from ocean and freight rate benchmarking platform Xeneta.
