Risen and Longi have revealed plans to each build 10 GW factories, while Canadian Solar has reported solid earnings and Daqo has secured a big polysilicon order.

Sunova Solar is offering five versions of its new solar panels, with power outputs from 555 W to 575 W and efficiencies ranging from 21.4% to 22.2%. They have a temperature coefficient of -0.31% per degree Celsius.

Chinese solar manufacturing giant Longi has announced the achievement of a world record 26.81% conversion efficiency from a cell utilising heterojunction technology on full-size silicon wafers in mass production. The company said the measurement has been validated by Germany’s Institute for Solar Energy Research.

As Longi and other solar manufacturers kick off massive growth in hydrogen generation capacity, expect large price decreases resulting from steep learning curves, echoing the rapid advances experienced by the solar power industry since the 1970s.

Australia features prominently in the top 10 but the latest edition of Ernst & Young’s renewables attractiveness index rates India as the top market for solar investment while Spain, Germany and the United States are the top three markets for corporate power purchase agreements.

China manufacturer DAH Solar offers four versions of its new panels, with power outputs ranging from 540 W to 555 W and efficiency ratings from 20.89% to 21.48%. The modules are reportedly ideal for steel rooftops with small installation angles.

Panel shipments collectively worth hundreds of millions of dollars are blocked from entering the United States market as they have failed scrutiny under the Uyghur Forced Labor Prevention Act, said Reuters.

Chinese researchers have assessed the impact of residential rooftop PV arrays on energy use and surrounding air temperatures during extreme heatwaves. They found that panels with higher conversion efficiencies achieved the best results.

Longi has launched a series of modules featuring an all-new hybrid passivated back contact cell technology, with which it claims a maximum module efficiency of 22.8% in mass production. It will initially offer the modules in 54, 60, 66 and 72 cell formats, targeting rooftop and distributed generation applications.

“Australia’s critical minerals are at the centre of an important moment in history which could dictate the shape of the world that we will live in for the next century,” federal resources minister Madeleine King told the Rare Earth Conference in Canberra. With the strategy to grow critical mineral supply chains between Australia and the US gaining momentum, this concept of “friendshoring” was in the spotlight at All Energy 2022.
