NHPC Ltd. has issued a tender inviting developers to set up 1.2 GW of grid-connected PV projects, with an option for a further 1.2 GW under a greenshoe option. Bidders must submit their proposals by November 4. October 11, 2024 Uma Gupta Image: Adani Green EnergyBy pv magazine IndiaNHPC has launched a tender to select developers for 1.2 GW of grid-connected solar projects and up to 1.2 GW of additional capacity under a greenshoe option.The potential developers will build, own and operate the PV projects at locations across India.NHPC will buy and sell the solar energy to state-owned companies, distribution…

In a new weekly update for pv magazineSolcast, a DNV company, reports that Hurricane Milton’s impact on solar energy production will be minimal outside the southeastern United States because the system is rapidly moving offshore. October 11, 2024 SolcastHurricane Milton made landfall on Wednesday, October 9, bringing strong winds and heavy rainfall to much of the southeastern United States. However, the impact on solar energy production outside the region is expected to be minimal as the system quickly moves offshore. Outside of the Southeast, much of the continental US saw higher-than-average solar production in September, analysis using the Solcast API.Hurricane…

Telescopes could power isolated communities in Chile’s Atacama Desert New research published in ‘Nature Sustainability’ shows that integrating a renewable energy system for the AtLAST telescope in Chile’s Atacama Desert could meet 66% of the energy needs of the nearby city of San Pedro de Atacama, providing a dual solution would provide for both scientific and infrastructure. local communities. The proposed system would reduce dependence on fossil fuels, which would benefit the Chajnantor Plateau Observatory and surrounding residential areas by providing cleaner, renewable energy. The study suggests that similar energy solutions at other nearby telescopes could reduce fossil fuel use…

This week, Women in Solar Europe (WiSEu) gives the voice to Sofie Graunbøl, Technical Sales and Sustainability Lead at the Danish Solar Polaris. She explains that solar installation is a male-dominated segment because many of the practices related to installation are based on men’s physical strength, making it more difficult to employ women. “This is an important issue that needs to be addressed so that the sector can improve,” she says. October 11, 2024 Women in Solar Europe (WiSEu)The solar industry, which is often seen as male-dominated, can benefit greatly from diversity. When women are involved in creating processes, asking…

Streamlined perovskite solar cells offer the path to cheaper, more efficient energy Researchers from the City University of Hong Kong (CityUHK) have developed a new manufacturing method that improves the efficiency, stability and affordability of perovskite solar cells, moving them closer to commercial viability. This study, published in ‘Science’, highlights how a simplified device structure designed by the CityUHK team could pave the way for future industrial-scale production of perovskite solar cells, improving their reliability and reducing costs. “The improvements in the stability and simplification of the manufacturing process of perovskite solar cells represent an important step forward in making…

Researchers in Spain have developed a new model to accurately estimate oil production and energy generation in agricultural voltaic installations built in olive groves. The proposed approach also allows to generate mathematical equations that estimate the influence of the system design variable. October 10, 2024 Emiliano BelliniResearchers from the University of Cordoba in Spain have developed a model to simulate solar radiation in agricultural voltaic installations deployed on olive groves with hedges.Compared to traditional olive groves, hedgerow olive groves allow a higher degree of mechanization and lower costs. They are widely distributed in Spain and Portugal, where they cover 100,000…

Vietnamese authorities have approved a new price framework for renewable energy imports from Laos, with basic import prices for wind and hydropower coming into effect at the end of 2025. October 11, 2024 Patrick Jowett Image: Matte brown, UnsplashVietnam’s Ministry of Industry and Trade has approved a new price framework for electricity imports from Laos to Vietnam.The updated bill, agreed this week, sets a maximum price of $0.0678/kWh for electricity imported from hydropower plants and $0.0640/kWh for wind power. Both prices are lower than the current rate of $0.0695/kWh and lower than retail prices of state-owned Vietnam Electricity Group (VND).The…

Grid services programs are managed by regional utilities and use energy stored in home batteries to help power communities when it is needed most, like during periods of peak electricity demand. This reduces reliance on costly and polluting power plants for electricity and, in return, provides incentives to homeowners from their own utilities. Incentive programs may serve as a discount on the purchase of an Enphase Energy System with IQ Batteries or as ongoing payments to participating homeowners. Most recently, homeowners who install Enphase IQ batteries are now eligible to participate in the following programs: Duke Energy PowerPair Program San…

JA Solar has filed two patent lawsuits against Astronergy in the Unified Patent Court (UPC). The procedures cover the tunneling silicon oxide layers (SiO2), the doped polysilicon layer and the electrodes used in tunnel oxide passivated contact (TOPCon) solar products. October 11, 2024 Emiliano Bellini Chinese solar panel manufacturer JA Solar is suing Chinese rival Astronergy for alleged patent infringement.JA Solar has filed two patent cases before the UPC, a joint supranational patent court of 18 member states of the European Union. The proceedings related to JA Solar’s TOPCon patents EP 2 787 541 B1 and EP 4 092 759…

The experimental device achieved an open-circuit voltage of 1.21 V, which is the highest value reported to date for high-efficiency perovskite photovoltaics. The cell is based on a photo-ferroelectric 2D/3D/2D perovskite junction in which 2D ferroelectric perovskite single crystals are integrated into the perovskite bulk. October 11, 2024 Emiliano BelliniAn international research group led by the Università Degli Studi Di Pavia in Italy has built a perovskite solar cell based on a photoferroelectric perovskite interface that reportedly helps reduce open-circuit voltage losses typical of perovskite PV devices.Ferroelectric materials have attracted the attention of the solar scientific community in recent years…
