Bidgely, an energy data software startup, has developed the 8760 Energy Model, a data set and report that provides utilities and industry stakeholders with behind-the-meter energy data, tracked at an hourly level throughout the year.

Taisei Corp. has installed second-life solar panels at Fukoka Airport’s new office buildings in Japan to test their performance for temporary power production.

TÜV Rheinland, Rheinische Netzgesellschaft, and GVG Rhein-Erft have supplied 100 households in Erftstadt, Germany, with gas mixed with 20% hydrogen. They have found there were no disruptions to systems, devices, or the network itself.

Sharp’s new IEC61215- and IEC61730-certified solar panel offers a power conversion efficiency of 22.07% and a bifaciality of more than 80%. The operating temperature coefficient is -0.30% per C and its power tolerance is 5%.

Scientists have used the US National Renewable Energy Laboratory’s (NREL) HOMER software to calculate the degradation of solar panels deployed in two rooftop PV systems operating in Germany since 2003. Their calculations focused on the energy productivity of the systems.

Researchers in China have built one of the most efficient carbon electrode perovskite solar cells ever reported to date. The device uses an organic/inorganic planar hole transport layer structure that purportedly has superior electrical contact.

Australian gravity storage startup Green Gravity has revealed that it will build a new R&D facility in the Australian state of New South Wales.

UK-based Ideal Heating has developed an air-source heat pump for the UK residential market. It is available in two versions with a heating output of 8.2 kW or 10.3 kW and uses R32 as the refrigerant. It says the heat pump can be paired with rooftop solar to maximize self-consumption.

The Fraunhofer Institute for Solar Energy Systems (ISE) has replaced the 2011 UL 1699B standard with its new IEC 63027 standard for inverters, incorporating arc fault detectors. The objective is to improve safety and efficiency in inverter technology.

Swedish scientists have created a contract to help renewable energy producers and retailers to pay high imbalance costs. The new framework could boost clean energy profits by up to 4.8% and retail profits by more than 7%, claim the researchers.
