Sofar, a China-based inverter and battery manufacturer, has introduced a new series of microinverters for balcony solar arrays and rooftop PV systems. They have a 97.5% efficiency rating and offer between 500 VA and 2,400 VA of rated power.

A time-motion study by United States Department of Energy’s National Renewable Energy Laboratory shows that retrofitting installations of roof-integrated PV takes 7% less labour time than standard solar installations. For new construction, the installation time drops by 44%.

Australian miner QEM has shortlisted three non-binding indicative bids to develop, own and operate a proposed 1 GW of wind and solar energy to power its planned vanadium mining and oil shale project near Julia Creek in northwest Queensland.

Australian renewable energy startup Green Gravity has teamed with underground mining contractor RUC to accelerate the commercialisation of its gravitational energy storage technology which rests on moving weighted objects through disused mine shafts.

Australian developer ACEnergy is building an initial portfolio of 10 neighbourhood batteries totalling 50 MW/100 MWh across Victoria and New South Wales. The company is also engaging networks to lobby for reforms to the connection process and tariff structure in light of grid support the technology can offer.

Australian renewable energy developer Genex Power has entered into agreements with Japanese electric utility J-Power to receive a multi-million-dollar funding package that will support the delivery of its 2 GWh pumped hydro project in northern Queensland and the development of the 2 GW Bulli Creek solar and battery project in the state’s southeast.

French oil and gas supermajor TotalEnergies has signed an agreement with Gentari Renewables, the clean energy arm of Malaysia’s state-owned oil company Petronas, to jointly develop a 100 MW solar farm in southwest Queensland.

Research carried out by China‘s National Photovoltaic Quality Inspection Center shows that new n-type TOPCon modules are living up to their promise, outperforming the previous generation of p-type PERC products. Data gathered over six months from a fixed-tilt PV system showed that the n-type products produced 3.69% more energy, and also suffered much lower performance losses.

The world’s most efficient energy network, at an Antarctic research base, has had a solar upgrade, reports Tristan Rayner.

The South Australian government is calling for input from industry and consumers to help it determine what role rooftop solar, batteries, electric vehicles, green hydrogen and other renewable technologies will play in its future energy system.
