Fraunhofer ISE develops propane heat pump using only 146 g of refrigerant
Researchers at Germany’s Fraunhofer ISE have developed an optimized heat pump propane refrigeration circuit for single-family homes.
Rooftop PV system design to improve yield under partial shading
Scientists in India have proposed a new concept that improves the yield of rooftop PV systems under partial shading. This concept combines conventional total cross-tied (TCT) techniques with partial power processing converters (PPPCs), using a resonant switched capacitor converter (RSC) and a switch inductor converter (SLC).
Bslbatt unveils 100-mm batteries for rooftop solar
China’s Bslbatt says its new batteries have 10.24 kWh of storage capacity and a nominal voltage of 51.2 V. It measures 700 mm x 980 mm and is 100 mm thick.
SMA unveils hybrid inverters for residential applications
SMA’s new one-phase hybrid inverters have efficiency ratings of up to 97.5% and European efficiency ratings of 96.8%. They are available in four versions, with power outputs ranging from 3.6 kW to 6 kW.
Japan’s vast wind and solar resources
To achieve its 2050 carbon neutrality commitment, Japan must eliminate greenhouse gas emissions from fossil fuels, as they comprise nearly all of its emissions. Fortunately, Japan has everything it needs to become energy self-sufficient, in the form of solar, wind, and pumped hydro energy storage.
Virtual power plants roll out across the U.S.
Virtual power plants (VPPs) coordinate distributed resources and demand for a more resilient, cost-effective energy transition. And they are gaining traction in the United States.
SolarEdge unveils bidirectional EV charger
SolarEdge’s new bidirectional DC-coupled electric-vehicle (EV) charger enables vehicle-to-home and vehicle-to-grid applications and can seamlessly integrate with its home energy systems. It is scheduled for release in the second half of 2024.
3Sun unveils 480 W n-type HJT solar module with 25% efficiency
Italy’s 3Sun, a unit of Enel Green Power, has developed new monofacial PV modules based on n-type heterojunction (HJT) G12 solar cells. The M40 series for rooftop applications has power ratings ranging from 440 W to 480 W and an efficiency of up to 25%.
High pressure drives record heat, PV generation across South-East Asia
In a new weekly update for pv magazine, Solcast, a DNV company, presents the solar irradiance data it collected for South-East Asia in May.
Maxeon, Samsung to integrate heat pumps with residential PV
Maxeon and Samsung have developed a cloud-to-cloud system to transmit data from Maxeon’s PV panels and batteries to Samsung’s home platform. The heat pump integration enables the use of surplus PV energy to preheat rooms at specific times.
