Hail risk remains top issue faced by solar projects
Hail damage remains a top risk to large-scale solar assets, according to an annual report from kWh Analytics.
Sunnova files for bankruptcy
US residential solar company Sunnova has entered into asset and power purchase agreements to support operations while it seeks a buyer.
Ukraine’s ‘twin cities’ project funds solar for community energy resilience
The Ukrainian government is launching a €2 million ($2.3 million) pilot project with the municipality of Grafenwörth, Austria, to expand solar infrastructure and enhance local energy resilience.
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.
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.
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.
New cooling gel could raise PV module efficiency by 12%
Researchers in Saudi Arabia have developed a hydrogel composite that absorbs moisture in solar modules overnight and facilitates evaporative cooling throughout daylight hours. The system has undergone lab tests and outdoor experiments on two continents.
