Manufacturing

Chinese manufacturer Hoymiles has developed a new line of microinverters with up to 96.7% efficiency and outputs of up to 2,000 VA. It said they can be connected with up to four high-power solar modules.

Queensland-based ReNu Energy will acquire up to a 20% stake in fellow Brisbane company, startup Vaulta, which has developed battery casings designed for reuse and recycling. Vaulta will use the eventual $1 million (USD 700,000) investment from ReNu to scale its manufacturing capability and expand domestic and offshore sales.

Geelong is set to become home to a $300 million (USD 210 million) lithium-ion battery gigafactory. Recharge Industries, part of a portfolio from US fund Scale Facilitation, is aiming to start construction by the end of the year, targeting 2 GWh of production annually in 2024 and 6 GWh by 2026. The company is reportedly aiming to produce batteries without using Chinese materials, and appears to be part of a deepening supply chain play between Australia and the US.

Following Risen Energy’s January announcement that the company is starting to mass-produce its n-type heterojunction technology (HJT) hyper-ion solar modules, it has revealed plans to increase production capacity to 15 GW by the end of 2023. Archie Chen, CEO of Risen Energy Australia, says n-type HJT panels will prove the favoured technology over the coming years, facilitating higher performing solar solutions.

Federal Energy Minister Chris Bowen has used the official launch of Australian PV panel maker Tindo Solar’s $11 million production and innovation facility in South Australia as an opportunity to highlight the importance of developing a domestic solar panel manufacturing industry.

Q Cells plans to manufacture 3.3 GW of solar ingots, wafers, cells, and finished modules in a new facility in the US state of Georgia.

Schneider Electric’s new Schneider Home platform includes a smartphone app to monitor and allocate energy resources.

Radovan Kopecek, the co-founder and director of Germany’s ISC Konstanz, says interdigitated back contact (IBC) tech could account for half of the global market for solar modules by 2030. He says IBC will start to dominate once TopCON and HJT get stuck at certain efficiency limits, and he believes TOPCon will be the first victim.

Trina Solar says its industrial tunnel-oxide passivated contact (i-TOPCon) solar cells, based on 210 mm wafers, have started rolling off the production line at its 8 GW factory in China. It will use the n-type cells to produce its new Vertex N modules, with power outputs ranging up to 605 W, and an efficiency rating of 22.4%.

Chinese manufacturer Huasun launched a new line of five heterojunction (HJT) solar modules in 2022, with power outputs ranging from 680 W to 700 W. The company has now added a new 715 W module to the series.
