Agrivoltaics postpone harvest, improve wine quality
Italian winemaker Svolta Srl has deployed an agrivoltaic facility at its vineyard in Apulia, Italy. The PV array allowed the cultivation of vines that are normally not viable at this latitude.
Perovskite solar cell based on lithium salt-doped spiro-OMeTAD achieves 25.45% efficiency
Researchers in China have proposed a new lithium-free doping strategy to fabricate spiro-OMeTAD-based hole transport layers (HTLs) for applications in perovskite solar cell. A PV device built with a salt-doped HTL achieved a record-breaking efficiency of 25.45%.
How to increase coefficient of performance in two-stage cascade heat pumps
A group of researchers in Thailand outlined a new methodology to identify the optimal temperature in two-stage cascade heat pumps using non-azeotropic refrigerants. Through their analysis, the scientists found that the coefficient of performance for simultaneous heating and cooling is affected by the pinch point temperature at the cascade heat exchanger, with lower temperature levels being responsible for a higher COP.
Scientists create setup to measure wave-induced power losses in floating PV
Researchers have measured the power loss of a 50 W panel stationed in a 30-meter wave tank. Based on ten different scenarios, they were able to draw an empirical equation for the prediction of power loss, with the highest loss being measured at 12.7%.
Innovation driving change in solar tracker market
Shipment volumes are growing in the global solar tracker market as innovation in project development drives demand. Joe Steveni, of S&P Global Commodity Insights, takes a look at the factors shaping the commercial landscape for trackers, from agrivoltaics and undulating terrain to Indian ambition and the United States’ Inflation Reduction Act.
AWM introduces three utility-scale solar products
The U.S. company introduced a hail-stow hanger, a hanger for north-south orientations, and rail system for clustered disconnect designs.
The Hydrogen Stream: Ballard restructures, Forvia supplies hydrogen tanks
Ballard Power Systems says it has started restructuring its global operations to cut costs due to slower hydrogen infrastructure development and delayed fuel cell adoption.
Solar cabinet for water disinfection systems
German fluid management company Lutz-Jesco introduced a system aimed at supporting pumping and water disinfection in cases of blackouts. The hub is preconfigured to work with solar panels, a battery charge controller, an inverter, and cabling.
DNV tool predicts hail probability at future solar sites
DNV, an independent energy expert and assurance specialist, has unveiled a service that assesses the probability of hail events at the site of future solar projects across North America, covering a period up to 30 years.
Sharp launches 450 W bifacial TOPCon module with 22.52% efficiency
Sharp’s new IEC61215- and IEC61730-certified solar panels have an operating temperature coefficient of -0.29% per C and a bifaciality factor of over 80%.
