Australian modular solar manufacturer 5B has secured a $20 million (USD 13.7 million) investment from the venture arm of British energy giant bp which will allow it to accelerate the development of its preassembled and relocatable modular solar technology.

Scientists in Egypt have created a self-cleaning, hydrophobic coating for solar panels that reportedly increases their efficiency by more than 30%. They used a coating solution based on polydimethylsiloxane (PDMS) and silicon dioxide (SiO2) nanocomposites, mixed with ethanol and isopropanol.

Moving with Australia’s Zeitgeist, Stuart Parry, managing director of Energy Storage Industries, is working to bring battery manufacturing onto Australian shores – and his approach is, if not novel, certainly well advanced. “It’s about being smart in how we do it,” Parry tells pv magazine Australia.

Boundary Power, a union between West Australian standalone power system (SAPS) leader Horizon Power and Ampcontrol, has installed its first off-grid system for an unnamed east coast utility in regional New South Wales.

Researchers from RMIT and the University of Melbourne have discovered high-frequency vibrations can release 14 times more hydrogen compared with standard electrolysis techniques. The discovery also has ramifications for the expensive, rare materials currently used in electrolysers. “With sound waves making it much easier to extract hydrogen from water, it eliminates the need to use corrosive electrolytes and expensive electrodes such as platinum or iridium,” research lead Amgad Rezk said.

An Italian startup has created a fully recyclable sticker that can be used to cover solar panels on rooftops or facades. It replicates high-definition images that can help to improve the aesthetics of solar arrays or turn PV facades into advertising billboards.

Researchers from UNSW have discovered a low-cost way to stabilise perovskite solar cells with a “triple function, cheap additive,” research lead Professor Hao tells pv magazine Australia. Perovskite cells using the additive have returned the best stability results yet seen in Australia, according to the team, and among the best in the world.

Australian technology start-up Infravision will team with New South Wales network operator Transgrid in a trial of a “next generation” line-monitoring system designed to optimise the performance of existing electrical transmission infrastructure and support the roll out of more renewable energy.

New South Wales network operator Ausgrid has signed an agreement with Simply Energy which will see the Melbourne-based energy retailer operate the electricity distribution company’s three community batteries in the National Energy Market.

Norwegian researchers have published a new study showing that the space between solar panels and rooftop surfaces might play a critical role in contributing to PV system fires.
