China’s Jiangsu province launches 27.3 GW offshore solar plan
The authorities in China’s Jiangsu province have launched an offshore solar development plan (2025-30), targeting 27.25 GW from 60 projects. The plan aims to connect 10 GW of offshore solar to the grid by 2027, with a goal of up to 20 GW by 2030.
A closer look at China’s Great Solar Wall
The US National Aeronautics and Space Administration (NASA) has published aerial images of the Great Solar Wall, China’s largest renewable energy project. The installation is expected to reach 100 GW of capacity by 2030.
Controlling water-to-water CO2 heat pump for optimal coefficient of performance
Scientists have designed a novel control approach for water-to-water heat pumps that use carbon dioxide. They relied on a virtual heat pump for their tests. The coefficient of performance (COE) improved by up to 14.6%.
Perovskite solar cell based on hole-selective interlayer achieves 26.39% efficiency
Researchers in China claim to have built a perovskite solar cell that can effictively reduce ion migration and offer superior stability. The device utilizes an ultrathin membrane made of a polymeric material known as PDTBT2T-FTBDT (D18), which reportedly offers conformal coverage on the surface of perovskite film due to its high fluidity.
Chinese PV Industry Brief: Xinyi Solar projects steep profit decline in 2024
Xinyi Solar says it expects a 70% to 80% profit decline for the year ending Dec. 31, 2024, due to low market prices, higher plant suspension costs, and inventory writedowns.
Scientists develop thermal model for floating solar with 15.45% efficiency
Scientists have developed a multi-physics thermal model for panels with a natural convection cooling loop and tested it against experimental data. They have also experimented with varying the coolant channel thickness and different coolants. The highest measured electrical efficiency reached 15.45%.
Chinese silicon giants cut production, driving price concerns
Major Chinese companies such as Tongwei, Daqo, and GCL-Poly have cut silicon production, driving concerns over rising polysilicon prices.
Aluminum frames lead solar panel costs amid shifting industry prices
SinoLink Securities says aluminum frames now dominate solar panel costs, as material price shifts reshape the cost structure of the PV industry and drive the need for innovation.
A tumultuous year for solar and batteries
In five key trends, pv magazine looks back over a year that saw PV module prices fall lower than many thought possible, while demand was restrained by grid congestion, among other challenges. Energy storage has had a strong year and geopolitics is seeing solar and battery manufacturing enter new regions as competition drives technical innovation.
The Hydrogen Stream: BNEF forecasts sharper green H2 price drop by 2050
BloombergNEF says green hydrogen will fall from a current range of $3.74/kg to $11.70/kg to between $1.60/kg and $5.09/kg by 2050, while Longi Hydrogen has secured a conditional $6.14 million equity investment and cooperation agreement with HydrogenPro.
