The British manufacturer said the new Ecomod products have sizes ranging from 14 kW to 70 kW and a coefficient of performance of up to 4.85. The systems can reportedly reach a supply temperature of 75°C. August 26, 2024 Emiliano Bellini Heating specialist Ideal Heating has launched a new series of monobloc air-water heat pumps for applications in commercial buildings.“Built with larger buildings in mind, these air-water systems can be cascaded to achieve the higher output required for commercial installations,” the manufacturer said in a statement.The new product is available in three versions with sizes of 14-18 kW, 26-32 kW…

Scientists have used different levels of Al₂O₃ and ZnO paraffin wax to improve the electrical and thermal performance of a photovoltaic-thermal (PVT) system. They have also developed a prediction model for this specific combination of hybrid nano phase change materials. August 26, 2024 Lior KahanaResearchers from Bangladesh and Australia have explored hybrid nano phase change materials (HNPCMs) for PVT applications. They used paraffin wax as a phase change material (PCM), which incorporated different levels of aluminum oxide (Al₂O₃) and zinc oxide (ZnO) nanoparticles. They also developed a prediction model.“In this study, Al2O3 and ZnO at different concentrations are incorporated with…

Ensuring a Sustainable Future with Solar Energy Solar panels have become increasingly popular as a sustainable energy solution, offering an eco-friendly alternative to traditional fossil fuels. As the world shifts towards renewable energy, solar panels are being installed on rooftops, in fields, and even integrated into everyday products. The surge in solar panel installations underscores the importance of understanding their lifecycle, especially what happens when they reach the end of their lifespan. Knowing what happens to solar panels after their useful life is crucial for several reasons. First, it helps ensure that the environmental benefits of solar energy are not…

Terahertz spectroscopy provides real-time insight into perovskite aging Hybrid perovskites are promising materials for advanced electronic devices such as solar cells and LEDs. However, their limited lifespan poses a significant challenge for commercial deployment. As these materials age, their performance deteriorates, creating obstacles for researchers and manufacturers alike. Addressing this problem requires not only improving the stability of perovskites, but also developing techniques to monitor their aging process in real time, which is crucial for improving their durability and efficiency. A recent study led by Prof. Yiwen Sun at Shenzhen University has introduced a new approach to observing the aging…

Australian battery maker Redflow has entered voluntary administration after failing to secure capital to scale up its X10 battery for larger projects. August 23, 2024 Ev Foley By pv magazine AustraliaRedflow, a Brisbane-based zinc-bromine flow battery manufacturer, has gone into voluntary administration after failing to secure capital to scale up its X10 battery to target larger projects.In March it secured AUD 1.1 million ($740,000) in funding from Queensland Critical Minerals and Battery Technology Fund to develop and build a large-scale version.The company has also secured AUD 20 million United States government funding in June 2024 for a 6.6 MWh zinc-bromine…

Scientists develop customizable perovskite waveguides with edge laser capabilities Researchers from the University of Warsaw’s Faculty of Physics, in collaboration with institutions from Poland, Italy, Iceland and Australia, have successfully created perovskite crystals with precise shapes suitable for non-linear photonics. These structures, including waveguides, couplers, splitters, and modulators, are notable for their ability to operate at room temperature and can significantly impact both classical and quantum signal processing. The findings, published in ‘Nature Materials’, highlight the edge-welding effect of the crystals, which is associated with the formation of exciton-polariton condensates – a state in which quasiparticles exhibit both light and…

In a new weekly update for pv magazineSolcast, a DNV company, reports that an increase in sunshine has resulted in record-breaking solar generation in several European countries in August, with this trend set to continue for the rest of the month. August 23, 2024 SolcastA high-pressure system centered over France, Spain and the Atlantic Ocean led to 20% more insolation than normal across Europe in August. The increase in sunshine has resulted in record-breaking solar generation in several European countries, with networks setting new highs for the month. According to analysis using the Solcast APIThis trend is expected to continue…

A research team from Poznań University of Economics and Business and SMA Solar Technology AG spoke to installers, designers, distributors and manufacturers in the Polish solar industry to identify the main barriers to PV development. They highlighted a lack of connection capacity and the prices of non-renewable energy sources as the main problems. August 23, 2024 Patrick JowettA team of researchers has analyzed the legal, economic, environmental, technical and social factors influencing the development of solar energy in Poland. Their research paper, “Determinants of solar photovoltaic development in Poland”, available in the October issue of Renewable energyidentifies key barriers from…

From pv magazine 07-08Agriculture is one of Brazil’s most important economic activities and is expected to produce BRL 2.46 trillion ($439 billion) worth of goods by 2024, according to estimates from the University of São’s Center for Advanced Studies in Applied Economics Paulo (USP). The academics estimate that agriculture will generate BRL1.65 trillion and livestock BRL801 billion, including machinery and service costs.The Climate Observatory, a Brazilian NGO, estimates that 617 million tons of the total 2.3 billion gross tons of CO2 The equivalent of Brazil’s emissions in 2022 came from agriculture. Deforestation, the country’s largest source of emissions, with 1.12…

HelioVolta HelioVolta, the developer of SolarGrade field operations software and provider of independent technical services for renewable energy sources, has published its second annual report SolarGrade PV Health Report. The report highlights findings from more than 100,000 PV system data points collected with the SolarGrade mobile app during site visits by field engineers to hundreds of projects across the U.S. and Puerto Rico. Key findings from the SolarGrade PV Health Report 2024 involve: 72% of inspections identified safety and reliability issues that required urgent resolution. Critical safety issues were found in 11% of inspections that required complete or partial power…
