Cooling PV panels with stagnant water layer
Researchers have developed a stagnant water layer cooling concept and tested it using seawater, tap water, and desalinated water. The panel temperature decreased by up to 8.2 °C, while power output increased by approximately 28%.
Scientists develop new floating box array for offshore PV
Researchers have tested a 9 x 11 floating box array for offshore photovoltaics in a large wave flume, under regular and irregular wave sequences. They have placed wireless gyroscopes on three of the boxes, representing the front, middle, and rear positions.
Operational faults cut returns in 19% of battery storage projects
A recent report from battery intelligence firm Accure reveals that while most battery energy storage systems operate reliably, nearly 19% of projects experience reduced returns due to technical issues and unplanned downtime.
New sieving tech for solar cell silver recovery
Researchers at University of New South Wales have reported details about a novel sieving-aids technology that improves the separation of metal fragments from other components when recycling end-of-life PV panels. The patented process reportedly enhances the recovery of silver.
Solis launches 16 kW residential and 60 kW commercial hybrid inverters
Ginlong Solis released two new hybrid string inverters that range from 9.6 kW to 16 kW for the residential market, and from 30 kW to 60 kW for the commercial market.
New research confirms rooftop PV affects urban temperatures, cooling demand
Using Lyon as a case study, an international research team has simulated the effects of rooftop photovoltaic (PV) coverage in an urban area at three levels: 25%, 60%, and 100%. The results have shown that solar panels can raise daytime temperatures by up to 0.72 °C, while cooling nighttime temperatures by up to 0.42 °C. In addition, daytime air conditioning demand has decreased by about 5%.
The Hydrogen Stream: KP Group signs MoU with Korea’s Jeonbuk province, AHES, and GH2 Solar
KP Group has signed a Memorandum of Understanding (MoU) with South Korea’s Jeonbuk State, South Korea’s AHES Co., Ltd., and GH2 Solar to collaborate on the large-scale deployment of electrolysis-based green hydrogen solutions.
DAS Solar developing 23%-efficient silicon solar cell based on carbon nanotubes
The Chinese module maker said the solar cell was developed with the support of Hebei University. The device uses a carbon nanotube-based hole transport layer that could be used in TOPCon and HJT structures to boost output and reduce complexity.
China wafer prices end four-week rally amid stable polysilicon, cooling demand
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Solar module prices to rise 9% in Q4, says Wood Mackenzie
Wood Mackenzie says module prices will climb as China ends export rebates and consolidates polysilicon production.
