The Chinese company said its novel Z-type mounting supports installation angles of 5°, 10°, and 15° and withstands wind speeds up to 45 m/s. It claims a lifespan of more than 25 years.

Chinese battery maker LiTime has introduced its 12V 320Ah Mini Smart Self-Heating Battery, offering 4,096 Wh of energy capacity and 2,560 W of continuous output power.

Scientists have developed a floating PV digital twin system, trained on data from 155 physical experiments, using a two-tier artificial neural network (ANN) with a high-fidelity model and a reduced-order model. Predictive performance reached R2 values of 0.9996 for PV surface temperature and 0.9189 for power output.

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%.

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.

China’s largest polysilicon producers have launched initial steps toward consolidation to curb overcapacity, but OPIS analyst Summer Zhang tells pv magazine that unresolved funding, capacity cuts and governance issues mean prices are likely to see only modest support in the near term without sustained capital injections and stronger downstream demand.

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.

The Chinese manufacturer has launched a new series of three-phase hybrid inverters ranging from 80 kW to 100 kW. They new products feature eight MPPTs with up to 42 A input current.

The battery is rated at a nominal 48 V and 314 Ah, with an ingress protection level of IP20.

Industry analysts say a new Beijing-based coordination platform created by China’s top polysilicon producers signals a turn toward managed capacity, as the sector tries to halt a steep price slide and mounting consolidation pressures.
