The BESS, which uses second-hand batteries at the Porsche Leipzig factory, has a capacity of 5 MW and an energy content of 10 MWh. The system can be used for short periods with an overload of up to 20%. The 4,400 battery modules of the Porsche Taycan electric sports cars are housed in four battery containers.The use of second-life batteries increases value in the battery value chain, as used batteries can remain in stationary storage systems for up to ten years before being recycled. The battery storage system of the Porsche factory in Leipzig is supplied with energy from the…

In a new scientific paper, researchers from King Abdullah University of Science and Technology (KAUST) in Saudi Arabia presented the 33.7% efficient perovskite-silicon tandem solar cell announced in May last year. They explained that the device is based on a perovskite additive known as tetrahydrotriazinium, which reportedly improves the phase stability of the perovskite film under heat and light conditions. August 12, 2024 Valerie ThompsonA team of researchers from King Abdullah University of Science and Technology (KAUST) has revealed the details of the 33.7% efficient perovskite-silicon tandem solar cell that the Saudi university announced in May 2023.In the study “Enhanced…

The U.S. Department of the Treasury, the Consumer Financial Protection Bureau (CFPB), and the Federal Trade Commission (FTC) have announced actions to address unfair and deceptive consumer acts and practices in the residential solar industry. The Treasury Department, the CFPB and the FTC have issued consumer advisories alerting the public to spot potential unfair and deceptive practices and encouraging consumers to file complaints of suspicious conduct with the FTC, CFPB and state consumer protection agencies. The Treasury Department, the CFPB and the FTC, along with the U.S. Department of Energy (DOE) and the U.S. Department of Housing and Urban Development…

HKUST researchers increase the stability of perovskite solar cells with a new chiral interface Researchers from the School of Engineering at the Hong Kong University of Science and Technology (HKUST) have developed a groundbreaking chiral structured interface in perovskite solar cells (PSCs). This innovation significantly improves the sustainability and energy conversion efficiency of the cells, marking a crucial step towards their large-scale commercialization. Perovskite solar cells, which use perovskite-structured materials, have gained attention due to their cost-effectiveness and ease of production compared to traditional silicon solar cells. However, despite the rapid progress, the path to commercialization has been slowed by…

DSD Renewables (DSD) is partnering with General Energy Corporation to deploy a 1.54 MW portfolio of rooftop solar projects across three Illinois park districts. The facilities, located in Elmhurst, Sycamore and Urbana, are estimated to generate approximately 1.8 GWh of solar energy annually that can be used to power operations and reduce the carbon footprint. These projects will integrate solar energy on a new scale into Illinois park districts, setting a standard for sustainable public space practices across the state and nation. “Illinois has a proven history of implementing energy efficiency programs, and these projects will only add to that…

Solarvest has signed five separate Green Power Agreements (CGPAs) in Malaysia through two joint ventures. August 9, 2024 Patrick Jowett Solarvest Holdings Berhad has signed five separate CGPAs in Malaysia. The agreements are with a Malaysian multi-asset exchange, two global semiconductor manufacturers and a data center service provider.The deals were made through two joint ventures: one with Savelite Engineering Sdn. Bhd. and TNB Renewables Sdn. Bhd., and another solely with TNB Renewables Sdn. Bhd.Under the CGPAs, Solarvest and its partners will own and develop two solar power plants in Lumut, Perak, and Kulim, Kedah – both in western Malaysia.The projects…

Doped Spiro-OMeTAD may not be essential for efficient indoor perovskite photovoltaics A new study challenges the conventional wisdom that doping Spiro-OMeTAD is essential for high-efficiency perovskite solar cells, especially in indoor applications. Researchers examined the performance of lead halide perovskite (LHP)-based photovoltaic devices using Spiro-OMeTAD as a hole transport material, comparing doped variants with variants that remained undoped. Although the undoped Spiro-OMeTAD devices showed a modest efficiency of 7.7% under standard 1-Sun illumination, their performance surprisingly improved dramatically under indoor lighting conditions. At 1000 lux, these undoped devices achieved an efficiency of 25.6%, which is quite close to the 29.7%…

Norwich Technologies, the parent company of subsidiaries Norwich Solar (EPC), RunTime Solar (O&M) and NorwichEV, is pleased to announce a further diversification of its business for strategic growth and greater impact in the renewable energy sector, by providing service under the new Breakaway Renewables company brand. Historically, the company focused on vertical integration and, as an EPC contractor, worked primarily on projects it developed in-house. This new division strengthens the company’s capabilities to develop sustainable projects for the portfolios of other companies. Since Norwich Technologies was founded in 2011, it has successfully developed and installed more than one hundred solar…

The pain of missed opportunities can be as much of a gaping wound as a CFO being told he just overpaid his federal business taxes. Now imagine that the overpayment was 10%, and the lost opportunity is the annual compound return on 10% less taxes every year beginning in 2021 and continuing through 2033. That pain was undoubtedly felt alongside the collective bewilderment of the majority of CFOs in the summer of 2024 when they discovered that this hypothetical setup was in fact real and that their company contributed more than $100 billion to overpaid corporate and wealthy individuals in…
