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.

Italian energy utility giant Enel Group has been granted a retail energy licence for Australia, with the company saying it will soon be one stop shop ‘greentailer’. Supported by its established Australian operations Enel X and Enel Green Power Australia, the new green energy retailer will first target commercial and industrial customers before expanding to residential customers.

The Victorian government has today announced it will put $5 million towards installing fast-charging stations across the state and $3 million in new charging infrastructure grants for local council and business fleets. The government also simplified access to its $3,000 electric vehicle subsidy, saying the program has led to a 200% sales increase in the last six months.

Batteries in South Australia have been paid to charge throughout September and October 2021 due to a record number of negative price intervals. Wholesale electricity prices were negative almost 40% of the time.

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

The Paris-based body expects the world will have installed almost 160 GW of solar this year, a record number, but still not enough to keep the prospect of a net zero global economy by mid century in sight.

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.
