Dubai-based Weco has unveiled a new lithium battery solution that can operate in parallel as a low-voltage storage system or in series as a high-voltage battery with no hardware changes. The batteries can be mounted on walls or set up in a stack configuration.

Scientists at Moscow’s Skoltech Center for Energy Science and Technology have developed a method of visualizing the formation of layers on battery electrodes during their initial operation. The observations reveal various mechanisms that could be optimized to improve battery performance and operational lifetime.

After managing to bear down on costs enough to compete with coal-fired generation, it appears solar developers in China now face a new hurdle to overcome – resistance from grid companies.

U.S. researchers have created a new model to assess the overlap between solar potential and underlying land use. The areas with the largest potential are the western United States, southern Africa, and the Middle East. The researchers concluded that croplands, grasslands, and wetlands are the top three land classes for PV projects linked to agricultural activities, while barren terrain, traditionally prioritized for solar PV system installation, ranked fifth.

Researchers at Germany’s Fraunhofer Institute for Integrated Systems and Device Technology IISB are trying to understand the causes of light and elevated temperature induced degradation (LeTID) in PERC solar cells. Initial investigations should provide a comprehensive understanding of the process and material dependency of LeTID and related degradation effects in monocrystalline and multicrystalline PERC solar cells.

Australian designer Chuck Anderson’s Lilypad is a 100% solar-powered villa floating off Palm Beach in north Sydney.

Researchers from the Solar Energy Research Institute of Singapore have concluded that utility-scale PV projects relying on bifacial panels and single-axis trackers deliver the lowest levelized cost of energy in most of the world. They found that the combination of bifacial products with dual-axis trackers is still too expensive, despite the higher yield. The second-lowest LCOE is offered by monofacial single-axis tracker plants.

Researchers in Iran have applied the Stackelberg leadership model to determine whether the creation of a closed-loop solar module supply chain – including panel refurbishing – is feasible. According to their findings, a similar supply chain may only be set up with public subsidies, which would ensure that costs for R&D, module production, and recycling are distributed between the government and all the chain’s players.

Researchers in the U.S. have demonstrated, using simulations, PV system generation can range from 18-60% of clear-sky potential during hurricanes – provided the arrays do not suffer damage. According to them, solar installations could continue to provide back-up power when grids are down during hurricanes, especially if coupled with energy storage.

The Chinese manufacturer this morning said the International Trade Commission had agreed with the initial determination issued by an administrative law judge in April, that Jinko and peers Longi Solar and REC Group had not infringed Hanwha’s solar cell passivation technology.
