Italy installed 5.23 GW of new solar in 2023, bringing its cumulative installed PV capacity to 30.28 GW by December, according to trade body Italia Solare.

Sharp’s new IEC61215- and IEC61730-certified solar panels have an operating temperature coefficient of -0.30% per degree Celsius, with 21.76% efficiency.

BloombergNEF says in a new report that developers deployed 444 GW of new PV capacity throughout the world in 2023. It says new installations could reach 574 GW this year, 627 GW in 2025, and 880 GW in 2030.

The Japanese electronics manufacturer said its new heat pumps are suitable for commercial, industrial, and multi-dwelling residential applications. The new products feature a rated power ranging from 50 kW to 80 kW and a coefficient of performance spanning from 3.2 to 3.4.

A Japanese-German research team has fabricated a TOPCon PV device by replacing common ion implantation techniques with plasma immersion ion implantation (PIII). The resulting device showed almost the same efficiency as TOPCon cells produced with conventional Beam line ion implantation systems.

Sharp has developed vehicle-to-home (V2H) electric-vehicle chargers for PV-powered homes, featuring 6 kW of charging/discharging rated power and an input DC voltage of 340 V. The wall-mounted devices are suitable for indoor and outdoor environments.

A Dutch research team has outlined a new method to assess the coefficient of performance of air-to-water heat pumps by considering ambient temperature and relative humidity. The model is based on the equalization of the so-called logarithmic mean temperature difference (LMTD), which determines the temperature driving force for heat transfer in flow systems such as heat exchangers.

Developed by scientists in Spain, the HelioSea system is reportedly able to ensure structural reliability in challenging marine environments. The research group proposed to use tension leg platforms that have been successfully applied to offshore drilling platforms, where stability is also paramount.

Slenergy has introduced a new residential PV system package featuring 425 W solar panels, a hybrid inverter, a high-voltage battery, and a Slenergy-branded heat pump. The package incorporates Internet-of-Things hardware for real-time data collection and intelligent control strategies.

Scientists in Korea have developed a compressed air storage system that can be used as a combined cooling, heat, and power system and provide heat and power to solid-oxide electrolysis cells for hydrogen generation. It showed an overall roundtrip efficiency of 121.2% and over-unity efficiencies in the range of 100% to 120%.
