New digital twin for floating PV application uses artificial intelligence
Scientists have developed a floating PV digital twin system, trained on data from 155 physical experiments, using a two-tier artificial neural network (ANN) with a high-fidelity model and a reduced-order model. Predictive performance reached R2 values of 0.9996 for PV surface temperature and 0.9189 for power output.
Bangladesh seeking contractors for 220 MW solar project
Electricity Generation Co. of Bangladesh (EGCB) has issued a procurement notice for a forthcoming 220 MW solar project near its existing 75 MW Sonagazi facility. Once completed, the installation will be the country’s largest solar plant to date.
Utilities risk penalizing efficiency by shifting to fixed charges
Shifting utility costs from usage rates to fixed monthly fees may penalize efficiency and fail to provide the financial incentive necessary to drive widespread electrification.
Waaree Energies tops 20 GW as India’s largest ALMM-approved PV maker
Waaree Energies crossed 20 GW of approved solar module manufacturing capacity after its Chikhli plant was added to the Indian Ministry of New and Renewable Energy’s (MNRE) Approved List of Models and Manufacturers (ALMM), strengthening domestic supply for utility-scale projects.
US state orders utility to enable flexible grid connections for community solar
Regulators in the US state of Colorado have ordered Xcel Energy’s local utility to introduce a flexible interconnection option aimed at lowering grid costs for community solar and energy storage projects.
Tata Power Renewable completes 1 GW DCR-compliant PV project for SJVN
Tata Power Renewable Energy Ltd has commissioned a 1 GW solar project for SJVN Ltd. in Rajasthan, India, supplying green electricity to Rajasthan, Jammu & Kashmir, and Uttarakhand. The installation was built in line with domestic content requirements (DCR).
India mandates 20% domestic content in battery storage projects
The Indian Ministry of Power has ordered all battery energy storage system (BESS) projects supported under the viability gap funding (VGF) scheme to meet a minimum 20% local content threshold, aiming to boost domestic manufacturing and innovation.
UK research calls for robust approach to rooftop solar fire safety
Research commissioned by the UK government finds rooftop solar panels can significantly influence fire behavior, particularly when the height gap between modules and the roof surface falls below critical limits.
Flexible front cover tested for glass-free CIGS devices
Researchers in Japan have developed an effective encapsulation with a PET front cover for copper indium gallium diselenide mini-modules. The lab devices withstood damp heat tests, retaining approximately 97 % of initial efficiency after 3,600 h.
China powers up world’s largest liquid air storage project
The 60 MW/600 MWh storage project is co-located with a 250 MW photovoltaic plant allowing for a high level of green energy self sufficiency.
