East-west vertical PV as antidote for soiling in desert regions
New research shows that east-west-oriented vertical PV installations can significantly help reduce soiling in desert environments. The scientists found that PV power generation can be up to 9% higher in vertical systems compared to conventional arrays.
Tokuyama plans polysilicon factory in Vietnam
Japan’s Tokuyama says it will build a new polysilicon manufacturing facility in an industrial park in Ba Ria-Vung Tau province, Vietnam.
New battery sizing approach for virtual synchronous generators, control-based grid-forming inverters
A group of researchers in Australia has outlined a new methodology to determine the minimum power rating of energy storage systems (ESSs) used for emergency under-frequency response. The ESS size must be calculated to maintain the frequency within the standard operating range.
New model to identify optimal power sizing ratio for solar inverters
Researchers in Malaysia have proposed a new approach to identify the optimal power sizing ratio to balance PV energy capture with inverter costs. The calibrated model is said to accurately reflect the relationship between inverter efficiency and real-world system behavior.
Japan’s 20th solar auction concludes with average final price of $0.029/kWh
Japan has allocated 93 MW of PV capacity in its latest procurement exercise. The lowest bid for a 1.9 MW solar project came in at JPY 4.5 ($0.029)/kWh, while the average final price was JPY 6.8/kWh.
PV module cooling tech based on water chamber
Scientists in Malta have created an after-market cooling solution that can be fitted to existing standard PV modules. The system is based on a water chamber placed at the backside of the module and can reportedly provide a net electrical energy gain of more than 9%.
Researchers find agrivoltaics have LCOE of $0.039/kWh, 7-year payback time in India
Indian researchers have compared the performance of an agrivoltaic system to monofacial and bifacial rooftop PV systems, and have found that the agrivoltaics setup had a shorter payback time and lower levelized cost of energy. Their analysis of performance considered panel temperature, power output, land equivalent ratio, and reliability.
ReCreate unveils details of US solar cell, module factory
The new venture is expected to bring 2 GW of solar module manufacturing capacity to the US market within 18 to 24 months.
Trina Solar probing potential breaches of TOPCon patents
Trina Solar says it has started evaluating potential violations of some of its patents for tunnel oxide passivated contact (TOPCon) tech. One of the patents focuses on the number of busbars and their width in TOPCon solar panels.
WTO accuses China of low transparency on state subsidies, including solar
The World Trade Organization (WTO) Secretariat has criticized China for an alleged lack of transparency in its state support framework and has urged the nation to improve its subsidy notification process.
