On his first day in office, President Donald Trump initiated a… 90 day review aspects of the Inflation Reduction Act and the Infrastructure Investment and Jobs Act. This would suspend the disbursement of certain funds, including grants and loans, until a review of legislation to ensure alignment with the new government’s energy policies. This falls within an executive order called “Unleashing American energy”, in which the president has identified “Ending the Green New Deal” as a key issue. The section focuses largely on electric vehicles, including eliminating the “EV mandate,” even though no such mandate exists. The President is demanding…

The cell uses a heterojunction device as the bottom cell and a perovskite top cell that integrates a hole transport layer made of nickel(II) oxide and methyl-substituted carbazole. January 22, 2025 Emiliano Bellini Taiwan’s Academia Sinica has announced that a group of researchers has developed a two-terminal (2T) perovskite-silicon tandem solar cell with an energy conversion efficiency of 31.5%. “In the future, the research team will further optimize the production process, increase the cell surface area, improve the stability of the stacked components and develop a production method that is more suitable for mass production,” the research institute said in…

The model was devised by an international research team and can also be used for hybrid wind-solar projects. According to its creators, it offers practical solutions for land use optimization and renewable energy planning. January 22, 2025 Emiliano Bellini A group of researchers led by Saudi Arabia’s King Fahd University of Petroleum & Minerals (KFUPM) has developed a new spatio-temporal decision-making model for the development of hybrid photovoltaic wind power plants, as well as individual wind and PV projects, in Saudi Arabia. “Our new model can identify the optimal locations for large-scale solar, onshore wind farms and hybrid systems in…

By SB staff January 22, 2025 Sol systems is transforming a historic 1,050-acre underground mine site in Randolph County, Illinois, through the construction of a $345 million solar project. The company announced the financial close of the 182 MW project on January 22. The system, called the Tilden Solar Project, will produce enough renewable energy to power about 33,800 homes in Illinois annually. It illustrates the ongoing energy transition by redeveloping a carbon-intensive mining site into a renewable energy source that will generate community and ecosystem benefits for decades to come. The Tilden project highlights Sol Systems’ unique approach to…

German inventor Klaus Krinner, who created a Christmas tree stand bearing his last name in 1987, was given the humbling task of setting up a pole in his yard to hang laundry. Not only did the laundry pole remain upright, but another great invention was created: the first Krinner ground screw. Credit: Terrasmart Today, ground screws are a common foundational choice for construction projects. They are used for signage, lighting, utilities and buildings of two stories or less. The ground-mounted mount has also gained popularity in the large-scale U.S. solar market, as PV projects take hold in areas with hillier…

Encore renewable energya renewable energy developer and operator, completed the first two solar projects it will both own and operate in Maine. The 4 MW Brooks Solar project. Encore renewable energy Brooks Solar, a 4 MW solar array in Brooks, and Alpine Street Solar, a 2.3 MW solar array in Oakland, were both powered last month. These are also the first two projects owned and operated by Encore as part of the company’s transition from project developer to a fully integrated independent energy producer. As a long-term asset owner, Encore will manage the operation and maintenance of the projects, including…

Mizzou scientists use layered crystals for next-generation energy solutions Researchers at the University of Missouri are delving into the nanoscale properties of halide perovskites, a material that could revolutionize energy-efficient optoelectronic technologies. By investigating its ultra-thin crystalline structure, scientists aim to unlock unprecedented efficiencies in solar energy and lighting solutions. Physics professors Suchi Guha and Gavin King of Mizzou’s College of Arts and Science are leading the research. “Halide perovskites are being hailed as the semiconductors of the 21st century,” says Guha, an expert in solid-state physics. “Over the past six years, my laboratory has focused on optimizing these materials…

Scientists in Peru have proposed a standalone, deployable system that quantifies energy losses due to dust build-up on PV modules. It uses both artificial neural networks and electrical models for predicting pollution loss. January 22, 2025 Lior Kahana Researchers from Peru have developed a standalone, deployable system that can reportedly quantify energy losses due to dust build-up on PV arrays before deployment. The proposed approach combines methods from neural networks and incremental guidance, which is one of the most widely used maximum power point tracking (MPPT) techniques due to its simplicity and low implementation complexity. “This system facilitates pollution analysis…

JinkoSolar’s latest n-type tunnel oxide passivated contact (TOPCon) modules delivered higher energy output per watt than a competitor’s n-type back contact (BC) modules in a three-month field test in Kagoshima, Japan, under different irradiation levels. January 22, 2025 Patrick Jowett During a three-month field test, JinkoSolar’s n-type TOPCon modules demonstrated significantly higher energy yield per watt compared to n-type BC modules. The field test, conducted by TÜV Nord at a field test base in Kagoshima, Japan, was conducted from October to December 2024 as part of a year-long study. It showed that JinkSolar’s TOPCon modules generated an average of 8.82%…

By Brad Kramer January 22, 2025 Global solar installations by region, 2020-2025 (GWdc). Source: Wood Mackenzie Installed solar capacity reached new heights in 2024, but growth will come to a standstill in 2025 amid several industry uncertainties, according to a new report. Wood Mackenzie recently released the “Global solar energy: four things to watch out for in 2025The report, which shows several limitations such as policy uncertainty, protectionist measures and interconnection and transmission bottlenecks, will stall the annual growth trend of solar deployment. Key themes to watch for include: adapting to a new, more uncertain policy paradigm, capitalizing on data…
