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.

Chinese state grid unveils plans for 100GW battery fleet

China’s largest state-owned grid operator and power utility plans to deploy the world’s biggest battery fleet and almost quadruple its pumped hydro storage by 2030, thus supporting the nation’s switch to renewable energy sources.

Aqueous zinc-ion battery with cycling stability of over 3,000 cycles

Conceived by scientists in China, the battery was built with a special hydrogel electrolyte made of polyacrylamide (PAM), zinc sulfate (ZnSO4), glycerol (GL), and acetonitrile (AN). The device showed high cycling stability of over 3,000 cycles, a high reversibility thanks to a Coulombic efficiency of up to 99.5%, and electrochemical performance of 185 mAh·g over 10,000 cycles.

New off-grid solar battery from China

Chinese manufacturer Bslbatt has unveiled a modular lithium-ion battery that can be used for the off-grid storage of solar energy. The device has a storage capacity ranging from 5.1 to 30.7 kWh and is claimed to provide steady operation for up to 6,000 charge cycles.

Weekend read: Expansions in n-type

The past 12 months have been a turbulent time for PV manufacturing. Rapid and impressive developments in technology have been accompanied by price increases up and down the supply chain, and energy shortages weighed on production in the second half of the year. Chinese n-type module manufacturer Jolywood is now pressing ahead with ambitious expansion plans despite the disruption. pv magazine publisher Eckhart K. Gouras and editor Mark Hutchins recently caught up with Cathy Huang, European sales director at Jolywood, to discuss the company’s plans to bring n-type TOPCon technology into mainstream production.
