In a new weekly update for pv magazineSolcast, a DNV company, reports that the Meteosat Third Generation (MTG) satellite is now beginning operational testing. The new satellite will provide sharper and more detailed, more frequent images, which will provide a significant boost to solar radiation estimates. December 27, 2024 Solcast According to analysis of early operational data by the Solcast Data Science team, solar forecasts across Europe and Africa will undergo a major upgrade as the Meteosat Third Generation (MTG) satellite begins operational testing. The new satellite, positioned alongside its predecessor from the Meteosat Second Generation (MSG) series, positioned at…
By Brad Kramer December 19, 2024 The Meadow ridge Continuous Care Pension Community (CCRC) in Redding, Connecticut, has flipped the switch on solar energy. The carport and rooftop solar installation will provide 897,700 kWh of electricity each year, accounting for more than 20% of the facility’s energy. The project is the long-term vision of the resident-led Solar Committee of Meadow Ridge and broke ground in August with the support of the retirement community’s ownership and management company, Senior Care Development LLC and Benchmark Senior Living. The solar panels at Meadow Ridge will save an estimated $7.6 million in electricity costs…
By Brad Kramer December 19, 2024 Northern Sun Energy has selected Castillo Engineering to provide design and engineering services for three projects Onyx renewable energy sources solar energy projects in New York and Louisiana. The projects have a total area of 18 MW and will be completed in the first quarter of 2025. One of the projects has even already been completed. The 5 MW community solar project in Troy, New York, uses fixed tilt racks and was commissioned in late November. The remaining two projects are located at the Fort Johnson US Army installation (Fort Polk) in Vernon Parish,…
The South African government has identified preferred bidders for 16 renewable energy projects, worth a total of ZAR44.2 billion ($2.4 billion) in investments, to boost solar and battery development. December 27, 2024 Brian Publicover South African President Cyril Ramaphosa Image: GCIS, GovernmentZA, Flickr The South African government has announced the appointment of preferred bidders for 16 renewable energy projects under its latest procurement programs, including PV installations and battery energy storage facilities. The projects represent a combined investment of more than ZAR 44.2 billion. South Africa’s Department of Electricity and Energy said eight solar projects, totaling 1.76 GW of contracted…
A review by the SUN DAY Campaign of data in two new year-end reports just released by the Federal Energy Regulatory Commission (FERC) and the U.S. Energy Information Administration (EIA) shows that the mix of renewable energy sources (i.e. (biomass, geothermal, hydro, solar, wind) now exceeds 30% of total U.S. utility-scale electric generating capacity (i.e. >1 MW) and is on track to reach capacity by the end of 2027 to reach 37%. In addition, they provided nearly a quarter of the country’s electricity generation through the first ten months of 2024. In addition, October marked the fourteenth month in a…
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…
