Sharp unveils 575 W TOPCon solar panel with 22.26% efficiency
Sharp’s new IEC61215- and IEC61730-certified solar panels have an operating temperature coefficient of -0.30% per C and a bifaciality factor of over 80%.
New model to predict defrost cycles, behavior of air-sourced heat pumps in cold weather
UK-based researchers have developed a novel method to estimate the amount of defrost cycles a heat pump will experience in the winter and how much energy it would require to implement the cycles. The results of their simulation showed a strong relationship between the number of defrost cycles and the ambient temperature.
E.ON acquires German PV distributor Klarsolar
E.ON has acquired German PV distributor Klarsolar, expanding its network of local businesses offering rooftop PV and residential storage systems. The financial terms of the transaction remain undisclosed.
Tesla Cybertruck can power homes
Tesla’s new trucks offer 11.5 kW of power output to homes, and 9.6 kW of output via five plugs.
Inverted perovskite-organic tandem solar cell achieves 23.07% efficiency via metal ion-doped absorber
A group of scientists in Korea has a hot-air technique instead of atomic layer deposition to fabricate a perovskite absorber that reportedly shows a higher film quality. They applied this film in a perovskite-organic tandem solar cell, which exhibited low open-circuit voltage losses and high efficiency levels.
California deals blow to rooftop solar
The California Public Utilities Commission (CPUC) has prohibited the use of battery-tied solar exports to offset delivery charges, following its decision to slash the value of standalone solar exports in order to encourage the pairing of systems with battery storage.
Up to 1,150 families sign up for UK heat pump scheme
The UK Department for Energy Security and Net Zero says the latest round for its Boiler Upgrade Scheme – an initiative awarding GBP 7,500 ($9,500) to families in England and Wales to replace traditional boilers for heat pumps – “surged” with a threefold increase in applications.
California’s lithium reserves could power 375 million EV batteries, say researchers
The Lawrence Berkeley National Laboratory has prepared a report, funded by the US Department of Energy, to thoroughly quantify the amount of lithium in an underground reserve in the Salton Sea, California.
The Hydrogen Stream: Rolls-Royce opts for SAF, not hydrogen in large aircraft
Rolls-Royce has told pv magazine that it prefers sustainable aviation fuels (SAF) for large commercial flights, but it continues to invest in hydrogen for mid-size aircraft in partnership with easyJet.
China Three Gorges commissions 1 MW pilot PV plant with perovskite panels
China Three Gorges has commissioned a 1 MW pilot solar plant with perovskite panels near Ordos, in China’s Inner Mongolia region. This marks the world’s first commercial PV system to use perovskite tech and features 11,200 modules from an undisclosed manufacturer.
