How to detect PV system underperformance using only AC-side inverter data
An Australian research team has developed a five-step, rule-based method that detects and classifies underperformance in PV systems using only AC-side inverter data. Validated across more than 1,000 systems, the approach offers a low-cost, low-intervention solution for improving reliability, fault response, and PV system performance.
New single-diode model tackles recombination losses in solar cells
UNSW researchers have developed an intrinsic-adjusted single-diode model that explicitly accounts for radiative and Auger recombination, improving I–V curve accuracy and reducing root mean square error by up to a factor of three. The model is claimed to better predict performance near open-circuit voltage and maximum power point.
ADB backs $350 million for three solar-plus-storage projects in Thailand
The Asian Development Bank (ADB) has approved a $350 million loan to Gulf Renewable Energy to build 194 MW of solar capacity, including two battery-integrated projects, in central Thailand.
Idemitsu switches on 2 MW of solar above rice paddy
Japanese petroleum company Idemitsu Kosan has announced its 2 MW agricultural solar power plant, installed 3.8 meters above a rice paddy, has begun operating. The project features a community-based model that returns a portion of the profits from power generation to the farmers.
Dominican Republic updates net metering rules for rooftop solar
The Dominican Republic has approved new regulations for rooftop solar, shortening approval times, digitizing processes, removing penetration caps, and increasing annual compensation for surplus energy to 100%.
Anti-glare film enables PV system at Brussels Airport
Warehouses De Pauw (WDP) has installed an 8.5 MW solar system at a warehouse near Brussels-Charleroi Airport, equipping roughly 40% of modules with Phytonics anti-glare film to prevent air traffic disruption while maintaining near-full energy output.
Space-based solar could be competitive by 2040, UK government finds
Investment and support could make small-scale space-based solar power (SBSP) viable, with potential for electricity generated in orbit to participate in UK contracts for difference (CfD) scheme according to new report. Launch costs have biggest impact on levelized cost of electricity (LCOE), according to analysis.
Rotterdam port advances 96 MW floating solar project for local use
A 96 MW floating PV project is set to be built at a dredging depot at the Port of Rotterdam. The array will not feed energy to the grid, instead serving local businesses. It is scheduled for operations in 2027.
The effects of solar module elevation on ground-mounted PV
Scientists in Hungary found that ground-mounted PV modules at an intermediate elevation of 1.1 m achieve the highest efficiency and power output due to improved airflow and reduced cell temperature. Their study also estimated a levelized cost of electricity of $0.0843/kWh and 577.78 kg CO₂ mitigation over 25 years, while noting results are specific to concrete surfaces.
AI can now predict solar cell efficiency from wafer quality
Korea University researchers have developed a machine-learning framework that predicts solar cell efficiency from wafer quality, enabling early wafer screening and optimized production paths. Using over 100,000 industrial data points, the approach combines predictive modeling, process optimization, and explainable AI to support photovoltaic manufacturing.
