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.
France surpasses 15 GW of installed solar power
According to the latest figures from France’s Ministry of Ecological Transition, 1,098 MW of solar was connected to the grid in the first half of this year, from 1,534 MW in the same period a year earlier.
Sri Lanka launches 30 MW solar tender
The Sri Lankan authorities are seeking project proposals for five PV projects – both ground-mounted installations and floating arrays – with power ranging from 2 MW to 10 MW.
Residential PV installation costs rising in Portugal
PV panels cost around €420 ($419) for a small 0.3 kW to 0.5 kW installation in 2021, according to data from service-hiring app Fixando. This year, installation costs have risen by about 40.5% to around €590.
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.
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.
