The great untapped potential in non-residential rooftop solar for LMI residents
The team used satellite imagery and AI to track unused rooftops with good solar potential, and found that it would bring reduced energy costs to residents.
Potential effect of the 2024 solar eclipse on solar energy production
To compensate for potential loss of solar energy flowing to the grid, grid operators will have to be ready to rely on other sources to ensure grid stability, as was done during the 2017 and 2023 eclipse episodes.
Iron-based redox flow battery for grid-scale storage
Researchers in the U.S. have repurposed a commonplace chemical used in water treatment facilities to develop an all-liquid, iron-based redox flow battery for large-scale energy storage. Their lab-scale battery exhibited strong cycling stability over one thousand consecutive charging cycles, while maintaining 98.7% of its original capacity.
Inverter undersizing not universally effective to reduce soiling losses
An international research team explained that, although inverter clipping is initially effective in mitigating soiling losses, these losses could become more visible with time, as solar module degradation makes clipping less frequent. They also warned that inverter under sizing alone may not be enough to mitigate soiling losses and suggested cleaning as an additional way to reduce them.

Car batteries can optimize the power grid
Australian researchers have found that if 10% of vehicles are electric and utilize V2G connections, they could reduce peak electricity demand at local substations by 6% and save car owners hundreds of dollars per year on charging costs.
