US scientists recently put different bifacial solar cells and modules through a series of tests at elevated temperature, humidity, voltage and mechanical stress levels. The tests revealed a range of light-induced and potential-induced degradation mechanisms that modules will likely suffer in the field.

Australia’s two dominant tracker companies, Nextracker and Array Technologies, are launching terrain following products which the companies claim mitigate, sometimes even eliminate, the need for earthworks on site, opening up a host of previously unsuitable land for solar. Nextracker has just completed its first terrain-following project in Australia, with Array Technologies’ line set for delivery in the second half of 2023.

“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.

Bolt-in electric vehicle kits in Australia have just got a leg up, with Melbourne startup Jaunt Motors joining forces with UK company Zero EV to operate a new, larger scale business to have production facilities and operations across Australia, the UK and, “very soon,” the US.

The US National Renewable Energy Laboratory (NREL) says in a new report that PV module lifetime extensions should be prioritised over closed-loop recycling to reduce demand for new materials.

A new study has calculated that the globalised PV module supply chain has saved billions for PV installers in Germany, the US and China. It also found that if strong nationalistic policies that limit the free flow of talent and capital were implemented going forward, solar panel costs would be 20-25% higher by 2030.

A US research team claims to have demonstrated that increasing the spacing of solar panels between rows improves PV system efficiency and economics by allowing airflow to cool down the modules. The method could improve a project’s LCOE by as much as 2.15% in certain climates.

US-based Nanotech Energy’s graphene battery uses proprietary electrodes with a thermally stable separator, and non-flammable electrolyte that is said to be inexpensive to manufacture. The technology is said to be superior in terms of safety and competitive in terms of cell performance.

BASF is currently testing Aeromine Technologies’ patented motionless wind-harvesting system.

Clean Energy Associates said in a new report that it expects polysilicon production capacity to exceed PV installations next year.
