Growatt opens Vietnam inverter plant, GCL-SI to build 12 GW PV panel factory
GCL-SI says it will build a new 12 GW solar manufacturing facility in China’s Jiangsu province, while Growatt has opened a factory with an annual capacity of 500,000 inverters and 100,000 batteries in Vietnam.
Tongwei unveils 21.7%-efficient shingled solar panels for residential PV
Tongwei is offering six versions of its monofacial monocrystalline panels, with power outputs ranging from 400 W to 430 W and power conversion efficiencies between 20.1% and 21.7%.
Longi releases new alkaline electrolyser
China’s Longi claims that its new ALK Hi1 electrolyser can produce hydrogen with an energy content of 4.3 kWh per normal cubic meter. It says the levelised cost of hydrogen could be up to 2.2% lower than other electrolysers on the market.
Trina Solar to expand n-type ingot capacity by 35 GW
In response to growing demand, Trina Solar has revealed plans to ramp up ingot capacity at a new factory in Xining, in China’s Qinghai province.
Solar wafer, cell prices continue to rise
Wafer prices rose by between 24% and 36% this week, according to new data from the China Nonferrous Metals Industry Association (CNMIA).
Polysilicon price rebound continues
Polysilicon prices started to rise in the second half of January, according to new data from the China Nonferrous Metals Industry Association (CNMIA).
Overcoming thermal issues of vanadium redox flow batteries
Chinese scientists have analysed reports of thermal issues with vanadium redox flow batteries (VRFB) and existing thermal management methods. They say the operating temperature should be maintained in the range of 10 C to 40 C to ensure VRFBs with high efficiency, weak side reactions, high electrolyte stability, and low crossover.
World’s largest hydrogen airplane makes first flight
The hydrogen stream: ZeroAvia tested its new 19-seat hydrogen-powered aircraft, Chinese scientists unveiled new tech to promote bubble removal in electrolysers, and Egypt-Japan University of Science and Technology researchers claimed that the most efficient hydrogen production systems are based on waste heat.
China mulling restrictions on polysilicon, wafer exports
The Chinese government is considering the introduction of export restrictions on solar wafers, black silicon, and silicon casting equipment. It has launched a public consultation process on the proposed measures.
Green hydrogen straight from the ocean: Adelaide researchers crack new method
Researchers from the University of Adelaide, along with international partners, have successfully used seawater with no pre-treatment to produce green hydrogen. The team did this by introducing an acid layer over the catalysts in situ. “We have split natural seawater into oxygen and hydrogen with nearly 100% efficiency… using a non-precious and cheap catalyst in a commercial electrolyser,” University of Adelaide’s Professor Shizhang Qiao said.
