Bromine-based flow batteries for renewables storage
Bromine-based flow batteries have the potential for high energy density in renewable energy storage. Their commercial adoption, however, remains challenging due to the cathode materials used for their construction. New research from China seeks to shed light on how to overcome these hurdles.
Growatt unveils solar rechargeable portable power station
Chinese inverter maker Growatt has launched Infinity 1500, a portable power station for off-grid applications.
Polysilicon maker predicts five year shortage of solar raw material
TBEA-owned Xinte Energy says it cannot produce polysilicon quickly enough to meet demand and wants shareholders to back its bid to quadruple its manufacturing capacity by mid 2024.
Molecular thermal energy system can store solar energy for 18 years
Developed by a Chinese-Swedish research group, the device is an ultra-thin chip that could be integrated into electronics such as headphones, smartwatches and telephones. It combines a Molecular Solar Thermal Energy Storage System (MOST) with a micro-fabricated system that includes a thermoelectric generator (TEG) with a low-dimensional material-based microelectromechanical system (MEMS).
Asia Pacific to lead global battery storage market, clock 68% share by 2026
The global battery energy storage market will grow to US$10.84 billion (AU$14.54 billion) in 2026, with around two-thirds of the demand concentrated in the Asia Pacific region.
Radiative cooling for PV modules – challenges and prospects
A group of international scientists has investigated the potential use of radiative cooling in PV systems, in a newly published review focusing on challenges and opportunities for the passive cooling technology.
Trina Solar achieves 25.5% efficiency in n-type TOPCon solar cell
The result was confirmed by the National Institute of Metrology of China. It was achieved with a cell size of 210x210mm.
Weekend read: The pieces that make China’s PV puzzle
Last year was a disappointing period for China’s PV industry, as high module prices restrained domestic demand and the ongoing pandemic continued to cause upheaval. This year looks more promising, even though the pieces of China’s PV puzzle have yet to fall into place. But sorting through them allows for a better understanding of the world’s largest PV market, reports Vincent Shaw, pv magazine’s China correspondent.
Growatt unveils new inverter for residential applications
The new device has an efficiency of up to 98.6% and a European efficiency of up to 98.1%. It features up to two maximum power point tracking (MPPT) inputs, with MPPT voltage ranging from 140-1,000V. While the inverter is currently only available in China and Europe, the company said it plans to launch it in Australia “soon.”
‘The major solar players will shift from PERC to TOPCon’
US analyst Clean Energy Associates made some notable predictions in its Q4 survey of the world solar manufacturing market, including echoing predictions made elsewhere that the new polysilicon production capacity coming online now will help arrest the spike in solar panel prices.
