Rooftop PV may ‘unintentionally’ exacerbate urban heat
New research from Hong Kong confirms that rooftop PV systems significantly contribute raise daytime temperatures in urban environments. The scientists explained that, although their findings highlight important urban resilience considerations, they should not detract from the broader benefits of PV systems for energy sustainability and carbon reduction.
Deakin University launches virtual energy network trial for solar trading
Researchers at Deakin University have launched a first-of-its-kind project exploring how Australian households and small businesses with solar and or battery systems can sell their excess clean energy to others without the technology.
CSP-driven multigeneration system combines hydrogen generation with compressed air, pumped hydro storage
Researchers have designed a novel multigeneration energy system that provides five outputs, namely electricity, hydrogen, cooling, heating, and hot water. The system is mainly powered by a solar heliostat system and incorporates compressed air and pumped hydro storage technologies for storing surplus power.
Tata Power hits 4 GW of solar module production capacity
Tata Power’s PV module subsidiary, TP Solar, has produced more than 4 GW of solar panels and 1.4 GW of cells at its factory in Tamil Nadu, India.
Liquid insulation for sustainable transformers
Liquid insulation is one of the ways of ensuring transformers – which convert electric power from high voltages to lower voltages – remain safe. Mineral oil, however, has been the main insulating liquid in industrial power systems to date and sustanaible alternatives are strongly needed.
Cyprus curtails more than half of renewables, including residential solar
Cyprus curtailed more than half of its potential renewable power in early 2025, including record residential solar cuts, as grid limits and a lack of storage strain its energy transition. Without swift investment in flexibility, analysts warn the country risks eroding public trust and delaying decarbonization.
Scientists build 29.5%-efficiency all-perovskite tandem solar cells through universal interfacial engineering
An international team of researchers used a novel interfacial treatment to improve the performance of perovskite solar cells across a range of narrow and wide bandgap single junction, tandem, and mini-module samples. An all-perovskite tandem solar cell demonstrated its use with a certified efficiency of 29.5%.
US solar manufacturing surges in Q1 amid policy fears, trade risks
US solar manufacturing ramped up sharply in the first quarter of 2025, supporting record levels of new capacity as solar and storage made up 82% of additions to the grid. But proposed legislation and rising import tariffs could cloud growth prospects.
US residential solar lender Mosaic files for bankruptcy amid policy uncertainty
US residential solar lender Mosaic has filed for Chapter 11 bankruptcy amid rising interest rates and policy uncertainty, joining a wave of financial distress sweeping the sector. The company, which backed more than $15 billion in home energy loans, will pursue a court-approved restructuring backed by existing lenders.
Sojitz, Kansai Electric sign 20-year PPA to power titanium plant in Japan
Sojitz has signed a 20-year corporate power purchase agreement (PPA) with Kansai Electric Power and Osaka Titanium Technologies to deliver solar energy from hundreds of distributed-generation sites.
