Cobalt-iron catalyst boosts zinc-air battery stability and performance
Engineers at Monash University in Australia have developed a new catalyst they say could bring zinc-air batteries “closer to real-world, grid-scale and transport uses.”
Swiss startup offers timber-framed solar carport
Urbanpv has developed a timber-framed 46 kW parking lot design for ten parking spaces including the access lane.
Enhancing dual-axis solar tracker performance with new optimization techniques
Researchers in India have developed two solar tracker optimization techniques can purportedly increase power generation by up to 54.36% when combined. One uses a light sensor and the other relies on data from GPS and a real-time clock.
Spanish startup offers portable solar-plus-storage generators for irrigation
Spanish startup Nomad Solar Energy and Full&fast have deployed a portable solar-plus-storage system at a Madrid farm to provide off-grid power for irrigation.
Enpal unveils residential heat pump for large heating loads
The German company is introducing its own heat pump with a heating output of up to 16 kW and a maximum flow temperature of 80 C. The system is designed to meet rising demand in large single-family homes and unrenovated existing buildings.
Optimization strategy for PV-powered EV charging stations relying on V2G
Scientists in China have created an optimization technique for an electric vehicle charging station that uses PV, battery storage, and a vehicle-to-grid operation. Considering the uncertainty of PV generation and the randomness of EV load, the system uses two-level optimization, day-ahead and intra-day.
Korean scientists achieve 21% efficiency in polycrystalline solar cell for underwater environments
The cell was fabricated with a 2.3 nm-thin layer of gallium oxide, a silver busbar aimed at improving charge collection and silicon nitride anti-reflection coating. It was encapsulated within a watertight 3D-printed box to ensure impermeability.
Optimum tilt angle for PV systems ranging from 0° to 90°
A Slovak research team has developed a mathematical model for determining the optimum tilt angle of a solar system ranging from 0° to 90°. Their framework was tested on an experimental setup in Czechia and attained 93.9% accuracy in predicting the system’s energy balance.
Japan launches subsidies to accelerate perovskite solar deployment
The Japanese government has launched applications for two targeted funding schemes to accelerate deployment of lightweight perovskite solar tech and incentivize battery-backed systems that enhance grid resilience and economic viability.
Solar-Fabrik debuts back-contact solar module for residential, C&I applications
The German manufacturer said its full-black back-contact solar panel has a power conversion efficiency of up to 23.52%.
