Chinese inverter and storage company Sungrow and Australian developer Green Gold Energy have signed an agreement to collaborate on “at least” 500 MWh of battery storage projects within the next three years – most to all of which will be DC-coupled. Relatively new to Australia’s grid-connected battery landscape, DC-coupled batteries will soon be able to trade on lucrative FCAS markets thanks to imminent rule changes, providing a firmer foothold for the technology in Australia.

An international research group led by Longi Central R&D Institute has published a paper describing Longi’s heterojunction solar cell based on a full-size silicon wafer that made a sensation in November, as it beat the long-lasting efficiency record held by Japanese manufacturer Kaneka for years. The researchers attributed the cell efficiency improvement to the implementation of a p-type amorphous silicon hydrogenated layer together with a modified transparent conductive oxides contact, which they said greatly reduced the cell contact resistivity.

Researchers from Switzerland’s École Polytechnique Fédérale de Lausanne have unveiled a new solar dish plant design, while Plug Power has delivered its first electrolyser system to Europe.

Construction of the South Australian section of the $2.3 billion (USD 1.56 billion) EnergyConnect infrastructure project, which will link power grids across three states, is now more than 50% complete with ElectraNet announcing the high-voltage interconnector is on track for release of full power transfer capability by mid-2026.

Australia is at risk of over-mining key transition minerals by relying on “overblown” demand assumptions, according to a new report which warns policy steps to encourage responsible and sustainable use of critical minerals, such as improved battery recycling, are being ignored.

Zhengrong Shi and his company, Suntech, are true pioneers of the Chinese solar industry. While Suntech burned bright, and eventually flamed out, under Shi’s leadership, the company’s solar ecosystem and innovation persist as China’s PV market surges past 100 GW(AC) today.

The Australian Energy Market Commission says the regulatory process for new transmission network projects must be overhauled to strengthen social licence and speed up the multi-billion-dollar expansion of the grid that is critical to the transition from coal to renewables.

Chinese solar module maker Risen Energy has launched two new n-type panels into the Australian market, targeting both the rooftop and large-scale PV markets.

Local government in the Dutch province of North Brabant will deploy a 500-metre-long solar array on a bike track and test its performance over a five-year period. The PV system will be integrated into the asphalt top layer and will consist of 600 solar panels of an unspecified type.

Public housing tenants in the outback town of Alice Springs are set to share in the benefits of renewable energy with the Northern Territory government launching a rooftop PV and battery energy storage trial that will help inform the planning of future public housing builds and management of solar power on current stock.
