Solar, geothermal heat pumps for heating, cooling demand in office buildings
Photovoltaic-thermal panels and geothermal heat pumps could mostly cover the heating and cooling demand of office buildings, according to new research from Greece.
The case for residential solar sharing
Technische Universität München researchers have run a series of tests to investigate the growing share of rooftop PV in Germany. They found that the sale and purchase of electricity between households could reduce consumption peaks and prevent grid bottlenecks.
Hanwha Solutions to set up TOPCon module production line, build EVA factory
Hanwha Solutions has unveiled a $548.8 million plan to enter the TOPCon module business and expand its EVA production capacity in South Korea.
Perovskite solar cell achieves 24% efficiency, retains 87% of output after 100 days
Researchers at the US National Renewable Energy Laboratory claim to have achieved a breakthrough for high-efficiency perovskite solar cells.
IEA says global heat pump installations to hit 600 million by 2030
The International Energy Agency (IEA) says that the deployment of 600 million heat pumps by 2030 could cover 20% of the annual heating requirements of buildings throughout the world.
PV-powered direct air electrolysis module to produce hydrogen from moisture in air
Scientists in Australia have developed a new way to produce hydrogen using water from the atmosphere. They claim their new module can ensure stable performance and provide green hydrogen for remote areas.
Solar perovskite tandems and potential-induced degradation
Scientists have found that perovskite solar cells and perovskite-silicon tandems might be vulnerable to potential-induced degradation. They exposed tandem cell devices to PID stress and found that they lost as much as 50% of their initial performance after just one day.
Meritsun unveils 15 kWh lithium-ion battery for residential applications
Chinese battery provider Meritsun says its new 48 V battery has a storage capacity of 15 kWh and a rated capacity of 300 Ah.
Hydraulic robotic cleaning solutions for ground-mounted solar plants
France’s AX Solar Robot has unveiled two battery-free, hydraulic-powered cleaning solutions for ground-mounted PV plants. It is also distributing a modular battery-powered solution suitable for rooftop installations.
PV-driven rechargeable control module for ‘cyborg cockroaches’
Japanese researchers have built ultra-soft PV devices and ultra-thin electronics that can be placed on the curved abdomens of cockroaches without affecting their mobility. The system can be used to monitor hazardous areas, or for urban search-and-rescue operations.
