Swiss researchers develop snow model to optimize PV system design in alpine regions
The researchers have used computational fluid dynamics-based modelling of snow patterns in an effort to establish best practices to mitigate snow accumulation in alpine PV plants.
From scale to strength: How India’s solar industry is forced to become a global premium player
EUPD Research explores India’s rapid solar manufacturing expansion, its growing export potential, competitiveness relative to China, and the evolving trade and sustainability dynamics shaping global PV markets.
High pressure boosts eastern solar as storms hit North America’s northwest
In a new weekly update for pv magazine, Solcast, a DNV company, reports that North America experienced a highly variable solar performance in October, as a strong high-pressure system boosted irradiance across the eastern regions while cooler, cloudier conditions reduced solar potential in the Pacific Northwest.
Aermec debuts modular heat pump for residential, commercial buildings
The Italian manufacturer said its new WWMG heat pump system has a coefficient of performance of up to 4.98 and an energy efficiency rating of 16.30 BTU/Wh.
Spanish start-up Bihar Batteries to commercialize sodium-ion batteries in 2026
The company has produced its first sodium-ion battery prototype and, in collaboration with Spanish research institute CIC energiGUNE, developed sodium-ion cell prototypes that have shown “very promising results.”
How to reduce PV module temperature with frame perforations
Scientists in China have investigated how frame perforations can help reduce the operational temperatures of solar modules through air cooling. Their findings show that the number of perforations must be carefully calibrated, and that more is not necessarily better.
Alfa Laval launches once-through steam generator for thermal storage
The Swedish company stated that its new product was designed for use in compact, molten salt energy storage applications, eventually in combination with PV power. In its standard configuration, it can reportedly withstand temperatures up to 400 C and pressures up to 60 bar.
Forschungszentrum Jülich achieves world record 23.08% efficiency for copper-metallized heterojunction solar cell
The cell reportedly exhibits only a 0.4% efficiency loss compared to a reference device that underwent full silver metallization.
Bosch starts up 2.5 MW hydrogen electrolyzer in Germany
German industrial group Bosch says the Bamberg facility complies with European Union renewable hydrogen rules and will produce over one ton of green hydrogen daily.
Japan’s NGK discontinues manufacturing of sodium-sulfur batteries
The manufacturer cites rising material costs, heightened competition from lithium-ion batteries, and the slow uptake of long-duration storage technologies as the reasons for the decision.
