GoodWe has unveiled a new range of commercial and industrial (C&I) string inverters, with 100kW, 110kW and 125kW output models offering up to 10 maximum power point trackers (MPPT) and 21A DC input per string. December 9, 2024 Lior Kahana China-based PV inverter manufacturer GoodWe has launched a new series of C&I string inverters. The GT series includes 100 kW, 110 kW and 125 kW inverters, with a maximum input voltage of 1,100 V. The smallest inverter weighs 85 kg, while the other two models weigh 88 kg. They are all 93 cm wide, 65 cm high and 30 cm…
An international research team has observed how fire spreads in PV systems installed on flat roofs and discovered that a certain amount of energy is required for a fire to start and spread in the cavity under the solar panels . December 9, 2024 Emiliano Bellini A Slovenian-Norwegian research group has investigated how fire can spread in flat roof PV systems and found that the gap distance between the panels and the roofs, as well as the size of the ignition source, are key factors. “Our work builds on previous knowledge from experiments at Underwriters Laboratories (UL) more than a…
Policies and targets confirmed in a 138-page government plan to decarbonise Britain’s electricity generation by 2030. Solar energy and storage will play a key role alongside market reforms, changes to the planning process and a renewed queue for connections. December 13, 2024 Matthew Lynas The UK government has committed to having around 30 GW more solar capacity in the UK generation mix by 2030, as part of its Clean Power 2030 Action Plan unveiled on 13 December 2024. Targeting greater deployment of solar energy is just one of many measures included in the 138-page plan published by the Department for…
A Norwegian-Swedish research group has used multiple linear regression to assess whether 128 existing wind power plants in the Nordic countries can potentially be converted into wind solar power plants with cost-optimal PV capabilities and good net present value (NPV). Their modeling could potentially be used in all countries and latitudes. December 13, 2024 Emiliano Bellini A group of researchers from the Norwegian Institute of Energy Technology (IFE) and Sweden’s Uppsala University have outlined a new strategy to retrofit wind power plants into hybrid wind-solar installations. “Hybrid solar-wind power plants can be valued differently under different market conditions,” Øyvind Sommer…
Trina Storage recently installed a white paper about the safety and reliability of energy storage systems, written in collaboration with TÜV NORD. The white paper begins by analyzing the current landscape of energy storage systems, highlighting emerging market trends and application scenarios on the generation, transmission and demand sides. It highlights significant safety challenges, such as thermal flooding and electrical hazards, while outlining a framework for risk assessment and mitigation. The safety of energy storage systems fundamentally depends on the safety of the products that comprise them. The white paper emphasizes that ensuring intrinsic battery safety is key to stable…
Researchers in China have integrated a wide bandgap perovskite solar cell with a hybrid back contact device into a four-terminal tandem cell that achieves high efficiency and stability. Key to the strong performance was a new surface passivation strategy that the research group employed for the top cell. December 12, 2024 Emiliano Bellini Researchers from Huaqiao University in China have fabricated a four-terminal perovskite-silicon solar cell (4T) with an upper cell based on perovskite material with an energy bandgap of 1.67 and lower surface defects. The scientists used a surface reconstruction method to remove the wide bandgap perovskite’s surface defects…
Scientists have designed a greenhouse system consisting of a battery energy storage system, hydrogen production and storage, as well as a semi-transparent PV array. The system is optimized for maximum net present value and minimum dependence on the electricity grid. December 13, 2024 Lior Kahana A research team led by scientists from Turkey’s Final International University has developed a self-sustaining greenhouse that uses a semi-transparent PV system (STPV), a battery energy storage system (BESS) for short-term energy storage, and hydrogen for the long term. term storage. The size of the proposed system was optimized to maximize net present value (NPV)…
Prime Minister Eluned Morgan and Tore Hattrem break ground at Swansea Greener Grid Park next to Statkraft’s Richard Mardon. Image: Statkraft. Statkraft has officially started construction on its Greener Grid Park, which aims to improve grid stability on the electricity grid in Wales. Welsh Prime Minister Eulned Morgan attended the project’s official groundbreaking ceremony near Swansea, along with Statkraft officials and Norway’s ambassador to Britain, Tore Hattrem. The Greener Grid Park will use six rotating stabilizers to mimic the turbines of a traditional power station, allowing the generator to keep electricity flowing to homes and businesses in Wales during grid…
New research from the Netherlands shows that the use of luminescent free-space solar concentrators can be used to significantly improve the performance of dual-sided solar modules in vertical residential installations. The scientists are confident that a variety of bifacial PV systems can be designed and deployed with this technology in the future. December 13, 2024 Emiliano Bellini Researchers from the University of Twente in the Netherlands have investigated how free-space luminescent solar concentrators (FSLSCs) can be used to improve the performance of bifacial PV modules in vertical PV installations and have found that electricity production could increase by up to…
TrendForce says silicon material and wafer prices have remained largely stable this week, while Longi Green Energy has signed a strategic deal with China Energy Construction for green energy projects. December 13, 2024 Vincent Shaw and Valerie Thompson TrendForce said in a new report that silicon material and wafer prices remained stable this week, with minor variations in some categories. Refeed monocrystalline silicon traded at $5.08/kg, dense silicon at $4.81/kg and n-type silicon at $5.50/kg. M10 wafers remained at $0.15/piece, while G12 wafers remained at $0.22/piece. N-type 182mm wafers were priced at $0.14/piece, and n-type 210mm wafers fell 1.43% to…
