By pv magazine 24/12-25/01 Just over a decade ago, Sandia National Laboratories founded the PV Performance Modeling Collaborative (PVPMC). According to Sandia, PVPMC increases transparency and accuracy in PV system performance modeling, helping to bring stakeholders together to improve modeling practices. Joshua Stein, senior scientist at Sandia, thinks it’s time for a similar effort to shed light on data analytics for monitoring PV plant performance. “There is a lack of standardization and harmonization in the way people talk about fault analysis and monitoring,” he explained pv magazine. Currently, some companies offer services that include data analysis and fault identification and…

The ‘Capture the oxygen’ strategy extends the life of lithium-ion batteries A team of researchers from POSTECH, led by Professor Jihyun Hong from the Department of Battery Engineering and Dr. Gukhyun Lim, has unveiled a key method to extend the durability of lithium-rich layered oxide (LLO) material, a promising cathode for next-generation lithium-ion batteries (LIBs). Their findings, published in Energy and Environmental Science, represent a major step forward in the development of sustainable battery technologies with high energy density. LLO materials provide a 20% increase in energy density over traditional nickel-based cathodes by replacing nickel and cobalt with lithium and…

BloombergNEF says green hydrogen will fall from a current range of $3.74/kg to $11.70/kg to between $1.60/kg and $5.09/kg by 2050, while Longi Hydrogen makes a $6, conditional equity investment and partnership agreement 14 million with HydrogenPro. December 27, 2024 Sergio Matalucci BloombergNEF said green hydrogen will fall from the current price range of $3.74/kg to $11.70/kg to between $1.60/kg and $5.09/kg by 2050, citing higher-than-expected future costs for electrolyzers. “BNEF had forecast steep declines in the price of green hydrogen in the past, but … has more than tripled its 2050 cost estimate, citing higher future costs for the…

Japanese plastics manufacturer Sekisui Chemical is investing in a 100 MW production line to make lightweight perovskite solar panels for low-support roofs, with an operational start in 2027. It will also acquire a production facility from Japanese electronics manufacturer Sharp. December 27, 2024 Valerie Thompson Sekisui Chemical said it will invest JPY 90 billion ($570.64 million) in a perovskite solar panel production line with an initial capacity of 100 MW, which will be put into operation in 2027. It also plans to commercialize its flexible perovskite solar panel technology, produced at its existing factory. facilities, in 2025. The investment includes…

The urban landscape is evolving. Vertical transportation becomes increasingly valuable to our daily lives as cities grow upward rather than outward. From elevators in skyscrapers to cable cars connecting mountainous regions, vertical mobility shapes how we move through spaces. But these systems consume energy – that’s where solar power enters the picture. The Energy Challenge  Traditional elevators and cable cars rely heavily on grid electricity. A typical elevator in a mid-rise building consumes as much energy annually as three American households. The energy footprint is substantial with over 17 million elevators worldwide and thousands of cable car systems. Cities account…

Emirates Water and Electricity Co. (EWEC) says it has secured four sites in the United Arab Emirates to develop 4.6 GW of solar and wind projects. December 27, 2024 Brian Publicover EWEC said it has secured four sites in Abu Dhabi to develop 4.6 GW of renewable energy projects, including PV and wind power plants. It claimed that the projects, which total 75 square kilometers, represent a crucial step in achieving Abu Dhabi’s 2035 Strategic Clean Energy Goal and the pledge to achieve net zero emissions in the United Arab Emirates by 2050. The developments include three solar power plants…

Scientists in the Netherlands have proposed a new test scheme for recycling silicon from photovoltaic panels at the end of their life. Their methodology helped create several wafer categories for recycling silicon for the production of new ingots, but also showed that most of the recycled silicon in the near future will come from p-type products, which will hardly be reused in a market now dominated by n-type modules. December 27, 2024 Emiliano Bellini A research group coordinated by the Netherlands Organization for Applied Scientific Research (TNO) has investigated how cleaned wafers or wafer fragments recovered from end-of-life (EoL) PV…

This is the fourth consecutive quarter that renewables have made up more than half of UK generation. Image: Vattenfall. During the third quarter of 2024, renewable energy sources accounted for 50.5% of electricity generation in Britain. Electricity statistics from the Department for Energy Security and Net Zero (DESNZ) show that fossil fuel production in the third quarter was 29% lower than in the third quarter of 2023, accounting for 17.9 TWh. This is the fourth consecutive quarter that renewables have made up more than half of UK generation. Electricity generated per fuel type. Source: Chart 5.1 DESNZ Energy Trends. Although…

Solar Energy Corp. of India (SECI) has allocated 600 MW of solar power at $0.036/kWh in its 1 GW solar tender, with Acme Solar, Adani Renewable Energy and ReNew emerging as winners. December 25, 2024 Uma Gupta By pv magazine India SECI has announced the results of its latest 1 GW solar tender launched under tranche XVIII. It has allocated 600 MW to three bidders at an average price of INR 3.06 ($0.036)/kWh. ReNew won 250 MW by offering the lowest tariff of INR 3.04/kWh. Acme Solar has secured 300 MW at INR 3.05/kWh. Adani Renewable Energy required 50 MW…

Chemical battery storage, led by lithium, has made such great strides in cost, capacity and technology that batteries are now positioned to accelerate our already exponential growth in solar energy. December 25, 2024 John Fitzgerald Weaver Image: Commercial solar man By pv magazine USA “But what happens when the sun sets?” This age-old refrain now has a definitive answer: “Batteries take over.” Over the course of 2023 and 2024, lithium-based batteries have gone from merely useful and somewhat expensive, to the brink of affordability and widespread adoption. This transformation has been driven by substantial cost reductions and increases in production…
