I agree it works both ways. I just wanted to remind that electric transportation is a small part of the overall electricity consumption (0.02 Quads https://en.wikipedia.org/wiki/Quad_(unit) https://en.wikipedia.org/wiki/Quad_(unit)), while industry & commercial accounts for 13.3 Quads, 3 order of magnitude lower. In "Transportation", there are a lot of non-electric consumption (in US in 2022: 89.45% oil, 5.7% biomass, 4.69% NatGas, only 0.08% electricity, and other) because only few trains and individual cars are using electricity the rest like boats, planes, and most trains in US runs on oil. So, yes it is good for electric vehicles to charge during the day when solar produces the most. But the vast majority of the electricity consumption (in US 99.9%) is from the Industry, Commercial and Residential while the transportation is only in US 0.1% (source: https://flowcharts.llnl.gov/sites/flowcharts/files/2023-10/US%20Energy%202022.png https://flowcharts.llnl.gov/sites/flowcharts/files/2023-10/U...). Most of the Industry, Commercial and even Residential needs electricity at night, and storing that kind electric energy (48.57 Quads per year... that is 9,246,178,571 barrel of oil or 0.2 barrel of U235) is currently difficult.
