PV redox flow battery with 4.2% solar-to-electricity conversion efficiency
Scientists in China have constructed and tested a device that uses redox couples paired with a single triple-junction amorphous-silicon photoelectrode. When tested under a xenon lamp simulating one sun, the device achieved an average solar-to-electricity conversion efficiency of 4.2%.
Off-grid floating PV-desalination system for hydrogen production
Scientists have simulated a solar-powered hydrogen production system comprising 32,050 photovoltaic panels, a pumping system, a seawater reverse-osmosis desalination unit, an electrolyzer, and a hydrogen storage tank. Operation of the system in Oman could potentially yield a levelized cost of electricity of $0.05/kWh and a levelized cost of hydrogen of $9.5/kg.
Using horizontally connected salt caverns for compressed air storage
Researchers in China have investigated the long-term stability of horizontally connected salt caverns used for compressed air energy storage. They found about 85% of the existing salt caverns in their home country are are suitable for this configuration.
Slovak researchers predict PV inverter output without weather sensors
Researchers in Slovakia have demonstrated a machine-learning framework that predicts PV inverter output and detects anomalies using only electrical and temporal data, achieving 100% accuracy in classifying inverter output states under static operating conditions at a solar installation.
Ambrion launches new all-in-one storage solutions
The Australian firm has introduced single-phase 5 kW and 6 kW AC output storage systems, as well as three-phase 10 kW and 12 kW models. Storage capacities of the new products range from 5 kWh to 40 kWh.
Rooftop bifacial PV can produce over 9% more power than monofacial systems in high-latitudes
A study analyzing urban bifacial PV systems in high-latitude areas found they can generate 9–13% more electricity than monofacial panels under snow conditions, particularly in winter, while also achieving a lower levelized cost of electricity. The research developed a techno-economic optimization model considering snow effects, panel orientation, interrow spacing, and operation modes, highlighting sensitivity to market conditions and discount rates.
