Sungrow unveils 5 kWh home battery system
Sungrow’s new residential battery energy storage system features a compact 182 mm design and is capable of handling a maximum charge/discharge current of 50 A.
Coupling solar-air source heat pumps with sand-based thermal storage floor
Scientists in China have analyzed the performance of a system linking a solar-air source heat pump heating system to sand-based thermal storage floor and have found it can maitain an average indoor temperature of 18.8 C, even when outdoor temperatures range from −18.4 C to 12.3 C.
Chinese scientists build 20.3%-efficient mini inverted perovskite solar modules via slot die coating
A team led by University of Electronic Science and Technology of China (UESTC) has found that pyrrodiazole as an additive in formamidinium iodide (FAI)-based inverted perovskite solar enables larger area devices made with industry-compatible slot die coating. Modules made using the technology achieved 20.3% certified power conversion efficiency and retained 94% of initial efficiency after 1,000 h in standard testing.
World’s first battery storage system to provide full active and reactive power services comes online
Blackhillock in Scotland is not only Europe’s biggest operating battery storage project. It is also the first one to provide a special set of grid stabilization services, procured under the electricity system operator’s Pathfinder 2, while also generating revenues from other critical services.
Turbo Energy launches residential storage solution
The Spanish company says its new storage system has a capacity ranging from 2.4 kWh to 9.6 kWh and a depth of discharge of 90%.
New technique to predict solar inverter temperature
An international research team has developed a novel approach for predicting inverter temperature through symbolic regression based on particle swarm optimization.
Indian scientists build 4T perovskite-silicon tandem cell based on hybrid heterojunction PV device
A research group in India has embedded a hybrid heterojunction solar cell as a bottom device in a four-terminal perovskite-silicon solar cell using a solution processing technique. The novel cell architecture, according to its creators, could be produced at significantly lower costs compared to conventional perovskite-silicon tandem designs.
UNSW develops PV panel recycling method that recovers cell metals for upcycling
UNSW researchers were able to recover silicon from end of life solar PV panels pure enough for re-use in silicon carbide-based devices. Their novel multi-step method which includes thermal and chemical processes, also recovers silver.
Taslink plans deep-sea cable to connect Australia, New Zealand
New Zealand venture Taslink has announced plans to build a 2 GW to 3 GW capacity high-voltage cable linking Australia and New Zealand to facilitate the day-to-day trading of electricity between the two nations.
Dutch province tests temporary solar shutdowns to ease grid congestion
A 2024 pilot study in the Dutch province of Zeeland found that homeowners who temporarily shut off their solar panels during peak generation reduced grid load by up to 57%.
