How to assess bifacial PV system performance on sloped terrains
Scientists have developed a precursor formulation for different PV simulation tools that can help calculate the expected performance of solar farms deployed on hilly slopes. Validation tests against an experimental setup showed an error of less than 3%.
Connecticut agency launches online solar project siting tool
The Department of Energy and Environmental Protection’s online is designed to support more efficient siting and permitting for solar projects.
Hidden devices found in Chinese-made inverters in the U.S., reports Reuters
U.S. officials are reassessing the risks posed by Chinese-made devices in renewable energy infrastructure according to news agency. Reuters cites two unnamed sources “familiar with the matter.”
U.S. renewables developers face daunting grid interconnection queues
Many grid operators are overwhelmed by projects, according to a report by Enverus.
RFP alert: Grant for research on the equitable economic outcomes of the IRA
The Washington Center for Equitable Growth seeks proposals for academic research on how the Inflation Reduction Act’s policy design, coordination and implementation affects equitable economic outcomes of the clean energy transition.
Quantum-based energy management method for PV-powered buildings
Scientists from Cornell University combined quantum computing with model predictive control to manage the energy of two PV-equipped university buildings. Compared to deterministic approaches, the quantum strategy achieved a 6.8% improvement in energy efficiency and an annual reduction of 41.2% in carbon emissions.
Inverted perovskite solar cell based on ionic salt achieves 26% efficiency
An international team led by the U.S. National Renewable Energy Laboratory (NREL) has used ionic salt for the electron transport layer of a perovskite solar cell to improve device stability and performance. Test results showed a 26% power conversion efficiency with 2% degradation after 2,100 hours of 1-sun operation at 65 C.
April storms cut Eastern U.S. irradiance as northwest surges
In another weekly update for pv magazine, Solcast, a DNV company, reports that strong jet stream and Eastern storms split solar conditions across the U.S. in April, with the east experiencing a downturn in solar irradiance while the northwest saw irradiance gains.
Solar grazing supports healthier soil, food for sheep, study finds
Solar sheep grazing helps to create a beneficial dual-use environment, found American Solar Grazing Association in a two-year study conducted at 31 different solar sites.
Sunrun supports California grid with 75,000 distributed batteries
Through a customer opt-in, batteries are coordinated in a virtual power plant that is expected to dispatch 250 MW of power over 2-hour peak demand events.
