Researchers in Spain have conducted a comparative analysis of annual solar hydrogen production for direct and indirect configurations and found that indirect systems not only produce more hydrogen, but also exhibit greater resilience to module power losses. August 21, 2024 Lior KahanaScientists from Spain’s Technical University of Madrid have conducted a comparative study of direct and indirect coupling configurations for PV and electrolyzers in green hydrogen (H2) production. The research was based on numerical simulations carried out with the software MATLAB, with weather conditions based on a typical meteorological year in Madrid.PV powered hydrogen systems where the input of the…

Researchers from Wuhan University of Technology in China have designed and synthesized a new non-fullerene acceptor for organic solar cells. One of their fabricated devices achieved the highest certified efficiency ever reported for single-junction organic solar cells.

EVLO Energy Storage, a fully integrated BESS provider and wholly owned subsidiary of Hydro-Québec, has announced that it has completed the commissioning of its first utility-scale BESS project in the United States. The contracted 3 MW/12 MWh facility is located in Troy, Vermont. The BESS will store energy during strong energy production times for later use during peak energy demand, eliminating the variability of renewable energy generation while delivering value to local utilities. The Troy project will also provide data to the U.S. Department of Energy (DOE) and Sandia National Laboratories to demonstrate how battery storage can enable the expansion…

Matt Marlow Altus strength has completed two ground-mounted solar projects in Maine, totaling 12.6 MW, with benefits delivered to the local community through the Altus Power Community Solar program. “As an early adopter of Community Solar, Maine is leading the way in enabling access to the benefits of clean, electric energy for its residents. We are proud to strengthen our presence and expand our Community Solar program in the state can expand,” said Matt Marlow, vice president of investments and structured finance at Altus Power. “By expanding our footprint in Maine, we can execute all…

Australia approves world’s ‘largest’ solar hub Australia on Wednesday approved plans for a major solar and battery farm that would export energy to Singapore, a project dubbed the “world’s largest solar area.” Authorities have announced environmental approvals for the $24 billion SunCable project in Australia’s remote north, which is expected to power three million homes. The project, which includes a series of panels, batteries and ultimately a cable connecting Australia to Singapore, is backed by technology billionaire and green activist Mike Cannon-Brookes. “It will be the largest solar area in the world – and heralds Australia as the world leader…

Scientists in Mexico have come up with a new cooling technology for solar modules that can reportedly improve PV energy generation by up to 2%. The system uses nanofluids embedded in a single-channel aluminum channel attached to the back of the panel. August 21, 2024 Lior KahanaResearchers from Mexico University of Sonora (UNISON) and the National Technological Institute of Mexico conducted a numerical study on the thermal performance of a single-channel cooling system for photovoltaic modules.In their simulation they used different types of nanofluids, such as aluminum oxide (Al₂O₃), copper(II) oxide (CuO) and zinc oxide (ZnO). In addition, they equipped…

The two leaders (photo) are committed to more green investments and teamwork. Image: Simon Dawson / No. 10 Downing Street Prime Minister Kier Starmer and Wales’ First Minister Eluned Morgan have joined forces to ‘supercharge’ the mission to make Britain a clean energy superpower. As part of an official visit, the two leaders committed to investing heavily in renewable energy development in Wales and the rest of Britain through the newly launched Great British Energy and public renewable energy developer in Wales, Trydan Gwrdd Cymru. Trydan Gwyrdd Cymru was developed in just 12 months officially launched last month. According to…

Longi Green Energy says it has received regulatory approval for a 1.05 GW wind-solar hydrogen project in Inner Mongolia, while Jolywood Technology says it has postponed its 7.2 GW residential solar project due to unfavorable market conditions . August 20, 2024 Vincent Shaw Longi green energy has received regulatory approval for a wind-solar-hydrogen project in Wulate Rear Banner, Inner Mongolia. Its subsidiary Wulate Rear Banner Longfuqi New Energy Technology will invest approximately CNY 6.974 billion ($975.7 million) to develop 1.05 GW of renewable energy capacity, including 850 MW of wind power, 200 MW of solar power and 157.5 MW/ 315…

Scientists tested various machine learning algorithms to predict the optimal tilt angle (OTA) of solar projects in 37 Indian cities, leading to improvements of up to 90%. August 20, 2024 Lior KahanaAn international group of researchers has used feature selection-based artificial neural networks (ANN) with various machine learning algorithms to predict the OTA of PV systems. They conducted their experiments at 37 locations in India, and depending on the ANN evaluated, the accuracy improvements ranged from 38.59% to 90.72%.“The OTA of the solar panels is one of the crucial variables that determine the effective installation and operation of PV systems,”…

The American power grid is electrifying through renewable energy proliferation, and homeowners are following suit by replacing gas powered vehicles and appliances with electric-powered options. However, certain homes are encountering the conundrum of having too high of an electrical load and not enough electrical service to back it. Savant is a recognized leader in both smart home and smart power solutions, developing solutions for balancing electrical loads in the age of in-home solar and storage. Ian Roberts, VP of sales excellence at Savant, is on this episode of Solar Spotlight to discuss the viability of energy load management. A written…
