New method to measure energy yield of bifacial PV systems
Canadian scientists have developed a new way to measure the energy yield of bifacial PV systems. They said they considered the spectral albedo of ground cover like snow and sand to predict energy gains of up to 2%, in comparison with the International Electrotechnical Commission (IEC) standard.
U.S. startup unveils portable solid-state lithium-ion battery for residential use
California-based Yoshino Technology has developed portable batteries using solid-state Li-NCM cell technology. The four variants come with power outputs of 330 W, 660 W, 2,000 W, and 4,000 W.
Trina Solar’s new 6.5 GW Vietnam wafer plant to exclusively supply U.S. market
Trina Solar said it will start operating a new 6.5 GW solar wafer factory in Vietnam from mid-2023 to exclusively supply the utility, commercial and industrial (C&I) segments in the United States, as well as the US residential solar market.
Sun-tracking vs. fixed vehicle-integrated PV
European researchers have evaluated the electricity generation, levelized cost of electricity (LCOE), and payback period of vehicle-integrated PV in EVs.
New electrolyzer to split saltwater into hydrogen
Scientists in China have developed a new way to split seawater into hydrogen without using a separate desalination process.
Growatt releases new battery for rooftop solar applications
Growatt’s new APX HV cobalt-free lithium iron phosphate (LFP) battery has a storage capacity of 5 kWh and a nominal voltage of 650 V.
Air-source heat pump for cold climates
Johnson Controls’ air-source heat pump prototype is designed for locations with temperatures below -20 F. Its York YZV and York HMH7 cold climate heat pumps can already operate in 5 F conditions.
PV windows cut energy use by 40% in glazed buildings, says NREL
The National Renewable Energy Laboratory (NREL) has shown that perovskite-based thin-film PV, transparent PV, and dynamic PV glazing technologies can reduce the energy use of glazed buildings by around 40% across eight regions in the United States.
Heat pumps competitive with gas boilers in some markets, says IEA
The International Energy Agency (IEA) says unsubsidized heat pumps are already competitive with gas boilers in mature markets including the United States, Canada, Japan, Italy, and China. It says global sales will soar to record levels by 2030.
Mitsubishi unveils air source heat pump
Mitsubishi has released a cascaded air source heat pump that can produce between 7.8 kW and 640 kW of heat. It is reportedly able to generate hot water at a temperature of up to 158 F without boost heaters.
