Lunar Energy announces new residential energy storage system
US-based Lunar Energy offers batteries, hybrid inverters, and shutdown devices.
Solar Leaders at Intersolar 2023: ‘It could be a difficult time going forward for solar module makers’
In the second interview of a series held at Intersolar 2023, pv magazine spoke with Karen Tang, Director – Editorial Lead Europe at Singapore-based market research company OPIS, about current price trends in the industry. She said solar panels may soon be bought at an average of $0.185/W but she also revealed that offers under $0.15/W are now becoming more frequent. Furthermore, Tang said prices may continue to drop in the future, with the bottom line being difficult to determine. Much will depend on the actual manufacturing capacity we will see coming online, which may not match the huge number of recent announcements released by module producers.
Flywheel mechanical battery with 32 kWh of storage in Australia
Key Energy has installed a three-phase flywheel energy storage system at a residence east of Perth, Western Australia. The 8 kW/32 kWh system was installed over two days in an above-ground enclosure, dramatically cutting the time needed to install the flywheel system.
Main causes of solar performance issues
A new report by HelioVolta shows that 62% of inspected PV projects have critical or major issues.
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.
