Overirradiance conditions may affect the operating performance of photovoltaic plants, the stability of the electrical grid, and the efficiency of inverters. A research team has warned these effects are currently not being given proper consideration by the solar industry.

Solar pre-cooling consists of using residential PV systems to run air conditioners to pre-cool residential and commercial buildings. It offers benefits in terms of mitigating low minimum demand in electricity networks, flattening the grid’s net demand profile, and reducing electricity bills.

Australian energy storage specialist 1414 Degrees has successfully commissioned a demonstration module featuring its thermal energy storage technology that harnesses the high latent heat properties of silicon to provide a potential zero-carbon solution for use in high-temperature industries.

The model utilises deep learning and image processing techniques and is said to offer “superior performance.” In the future, it might be able to differ between panels of PV and solar thermal systems.

New South Wales hydrogen technology company Hysata will install a 5 MW electrolyser unit adjacent to the coal-fired Stanwell Power Station in Queensland as part of a commercial-scale demonstration of its next generation tech.

Australia’s largest transmission network operator Transgrid has struck a deal with Chinese manufacturer ZTT International for the delivery of more than 17,500 kilometres of high-voltage conductors as it looks shore up supplies of key electrical equipment needed to deliver critical transmission projects.

The Australian Energy Market Commission has proposed new rules that would require developers planning major transmission projects to consult with communities and affected stakeholders earlier in the projects’ development.

South Australia’s Flinders University has launched a trial that will test bidirectional vehicle-to-grid charging technology that allows electric vehicles to either be recharged or used as batteries to provide back-up power to the grid.

Biwatt Power, a Chinese manufacturer, has developed new residential sodium-ion batteries with an efficiency rate of 97% and a projected lifespan of more than 3,000 cycles.

Western Australia battery tech company Altech Batteries has raised $13.3 million (USD 8.7 million) to advance the development and commercialisation of its sodium-chloride solid state battery project and to progress construction of a silumina anodes battery materials plant in Germany.
