Well, using electric vehicles does create more battery storage to charge using solar during daytime off-peak hours. You go to work, park your car in a parking equipped with chragers and your car charges while you sit and work. The parking lot and the neighbouring buildings can have solar panels on their roofs to supply the electricity. Same during night time off peak hours: you car can charge while you sleep mainly using excess nuclear or wind power. But this discussion is about public transport, which works equally better because during daytime off-peak hours people are mainly at work and half of the bus fleet can charge up. I'm sure going electric is not 100% clean, but it displaces smog from the cities and power generation can be diversified and even distributed. So in many respects it's better. It's definitely better for urban transport where you don't need hundreds of miles of autonomy. The rest of the vehicles that go outside cities can be switched to plugin hybrids running on LPG and DME, which are cleaner alternatives to petrol and diesel. When they get into urban areas they can switch to fully electric if the transport code requires it.
