The new bidding strategy, devised by an international research team, applies to the day-after and intraday markets. It uses a technique that converts results from probabilistic models into actual scenarios. Their method showed that it was able to generate higher revenues and reduce imbalances. August 8, 2024 Lior KahanaAn American-Dutch research team has developed a new bidding strategy for operators of PV installations participating in electricity spot markets. It is based on converting probabilistic solar energy forecasts into interdependent scenarios used in the multi-stage bedding strategy.According to the researchers, the new method can ensure higher incomes and fewer imbalances. “Accurate…

Sineng Electric has revealed that it has supplied its string PCS MV stations for what it claims is the world’s largest sodium-ion BESS, and China’s first 100 MWh-scale energy storage plant using sodium-ion batteries.The project consists of 42 BESS containers with 185 Ah sodium ion batteries, 21 power conversion systems and a 110 kV booster station. The project is being developed and operated by Datang Hubei Energy and marks China’s efforts to diversify from lithium to more abundant sources. Datang Hubei energy said it had started operating the project on July 2. It was connected to the grid on June…

An international research team has conducted a series of simulations to investigate how a cadmium telluride buffer layer can help increase the efficiency and stability of perovskite solar cells. Their experiment showed that the cell efficiency can increase from 11.09% to 23.56%. August 8, 2024 Emiliano BelliniA group of scientists led by the University of Agriculture Faisalabad in Pakistan has proposed to improve the efficiency of perovskite solar cells by adding a buffer layer (BL) made of cadmium telluride (CdTe), which reportedly improves charge carrier extraction while reducing device defects . .The researchers explained that the presence of a BL…

Scientists in China have proposed using polydimethylsiloxane films doped with soda glass to reduce the temperature of solar panels. The coating achieved a solar transmittance of 94.8% and a skylight emissivity of 95.3%. August 8, 2024 Lior KahanaA group of researchers from China’s Shandong University and Xi’an Jiaotong University have developed a radiant cooling (RC) cover for PV panels that can reportedly reduce their operating temperature by up to 3.72%.Radiative cooling occurs when an object’s surface absorbs less radiation from the atmosphere and emits more. This causes the surface to lose heat and a cooling effect can be achieved without…

John Bates Radial force has acquired four community solar projects in upstate New York, totaling 22.3 MW, from Galehead Development. Following the closing of each transaction, Radial Power will oversee the final development and construction of the projects, all of which are eligible for the state’s Value of Distributed Energy Resources (VDER) program. Galehead developed the projects in collaboration with members of the local community and National Grid. It owns and will continue to manage land assets for 14 MW of the portfolio under its Century LandCo. “Radial Power is proud to advance the energy…

Scientists in Morocco have designed a photovoltaic-thermal panel that uses a channel-box heat exchanger consisting of 94 channels connected directly to the PV module. The simulated design reportedly results in an overall panel efficiency of more than 90% and good results in terms of temperature inhomogeneity. August 8, 2024 Emiliano BelliniA group of scientists led by Chouaïb Doukkali University in Morocco has designed a photovoltaic-thermal solar panel based on a duct box heat exchanger, aimed at improving convective exchange.They explained that the proposed design offers the advantage of having the entire panel surface in direct contact with the fluid, while…

Community energy projects – that is, energy infrastructure owned in whole or in part by local communities and run for their benefit – have seen something of a rise in Britain in recent years. According to Community Energy England, the group that represents the sector, there are currently 583 community energy organizations operating in Britain, managing a combined renewable energy capacity of 398 MW. Last year, these groups generated 617 GWh of electricity, enough to power approximately 228,530 households. In short, community energy functions as follows: members of a community invest in renewable energy generation projects and receive interest on…

Researchers have designed a new tracking system that uses a computational optimization-based PID controller. The proposed tracker uses two different sensor types: a UV sensor and a microelectromechanical solar sensor (MEMS). The first calculates the intensity of UV radiation received from the sun, and the second predicts the sun’s path across the sky.

The US residential solar installer has filed for bankruptcy, one of the largest in a series of major bankruptcies in the sector. August 7, 2024 Ryan Kennedy and Pilar Sánchez MolinaBy pv magazine USAU.S. residential solar energy company SunPower Corp. (Nasdaq: SPWR) has filed for bankruptcy. Nevertheless, the situation does not affect the Solar panels from the SunPower brand, designed, produced and sold by Maxeon Solar Technologies in Europe and elsewhere outside the US and Canada. “Other than a product brand name, there is no existing relationship between them Maxeon and SunPower Corporation,” a spokesperson for Maxeon Solar said pv…
