Sydney-based solar pioneer 5B has today announced it will acquire IXL Solar’s Adelaide-based manufacturing business, with pv magazine Australia told the purchase will see 5B buy everything but the name, effective immediately.

Floating PV is a growing niche in the solar sector, but its offshore segment has proven more difficult to activate, largely because of the difficulty of open-water energy generation. Nevertheless, the potential of offshore floating PV is almost unlimited, and one Singaporean firm, G8 Subsea, is looking to leave the safety of harbours and reservoirs.

Developed by scientists in Turkey, a system prototype has operated at lower PV module temperatures and removed most of the dust accumulation. The researchers are now planning to improve the device by applying maximum power point tracking (MPPT) converter topologies.

With a new system for floating photovoltaic power plants, engineers from Germany want to make the application cheaper, higher-yielding, and safer. The result is somewhat reminiscent of a pufferfish, which also gave the system its name.

Malta announced a partnership with Betchel to deploy electro-thermal energy storage systems that are capable of durations of 10-150+ hours.

As power systems integrate more digital and inverter-based devices, the guidelines and technical standards for these resources are evolving, and none as quickly and urgently as cybersecurity standards. New approaches to cyber defence are now needed to protect more interconnected systems with diverse owners, manufacturers, and system architectures. However, current cybersecurity standards for energy devices are still patchy. Upcoming efforts are aimed at changing that, reports NREL’s Connor O’Neil.

As solar PV increases its share in the world’s energy mix, it is becoming increasingly clear how valuable the data gathered from renewable energy generators is in informing important decisions about operation, maintenance and grid integration. Yazeed Al Mousa examines the latest applications for artificial intelligence in PV project development and operation.

Western Australia has today announced the launch of its $35.5 million Virtual Power Plant trial, Project Symphony, which will examine the ways in which residents, utilities, and network operators can join forces to centrally orchestrate the output of rooftop solar, batteries and other distributed resources to best serve both customers and the grid at large.

German company sonnen, a wholly owned subsidiary of Shell, today launched a new residential battery storage system specifically developed for Australia and New Zealand. Chief Commercial Officer of sonnenGroup and Managing Director of sonnen Australia, Nathan Dunn, told pv magazine Australia its sonnenBatterie Evo is the culmination of a new approach and may go on to inform how its future products for global markets are developed.

AGL has “broken ground” at Torrens Island power station in preparation for the construction of its 250 MW/250 MWh battery which has drawn interest for being the largest planned grid-forming battery in the world.
