Sunways’ new three-phase inverters have efficiency ratings of up to 98.6% and European efficiency ratings of 98.2%. They are available in five versions, with power outputs ranging from 15 kW to 30 kW.

China has reduced the export tax rebate for solar products, lowering refunded taxes for Chinese PV exporters and eating into their profit margins. The move might force some companies to increase export prices to mitigate potential financial losses.

The Chinese manufacturer said the device is based on dense passivating contacts that reduce parasitic light absorption and improve passivation. It used a streamlined manufacturing technique that is reportedly about one-third more effective than TOPCon mainstream technology.

United States manufacturer Thornova Solar has started producing solar cells and modules in Indonesia. CEO William Sheng says the move is in line with changing US market regulations. It plans to supply customers with cells and modules from Indonesia, Laos or the US by mid-2025.

Independent clean energy think tank Climate Energy Finance has called for a $20 billion Future Fund mandate to enable renewables-powered processing of green metals and for measures to accelerate investment in firmed renewable energy at scale.

Australian energy gen-tailer Zen Energy is considering offshore opportunities, eyeing energy storage and green hydrogen projects in Taiwan and potentially other countries after securing a $43 million investment from Taipei-listed developer HD Renewable Energy Co.

Singapore could import large quantities of low-cost solar power from neighbouring countries using undersea cables, with the indicative cost being competitive with gas generation. Unlimited world-class pumped hydro energy storage is available in neighbouring countries in the range 50-5000 GWh to support very large scale transmission.

Research from the National University of Singapore indicates that Singapore could reach its 2 GW solar installation target by 2028, ahead of its 2030 deadline. The study suggests that the government could increase its long-term solar goals by adopting policies that promote better area utilisation, subsidies, and advancements in panel efficiency.

GoodWe has developed a residential solar carport that features its Polaris building-integrated PV (BIPV) panels. The carport, which is available in 4.8 kW and 8.0 kW variants, is designed to host one or two vehicles, respectively.

A Chinese-Italian research team has analysed the influence of different tilt angles on the thermal failure of the photovoltaic facades or roofs in fire conditions, finding that when the tilt angle exceeds 30 degrees, the time to failure increased significantly.
