> The vast majority of EVs charge at night when rates are low due to low demand. Not true. If you actually model 300 million vehicles across all of our time zones and with different utilization modalities, you soon find out power demands become very much constant throughout the day. That's not to say people cannot be incentivized to charge at certain times. However, you can't mandate that because everyone has different utilization patterns. If you have 15 million vehicles in California all charging between 6 PM and 6 AM you are going to have a serious power availability and deliver problem. Solar? Well, that would require two things. First, sufficiently large batteries at home. Second, TWICE the generation and storage capacity anyone has at home today. I have a 13 kW array. If I wanted to use it to charge two electric vehicles I would have to at least double the size of the array and probably get something like 8 Powerwalls (haven't done the math, maybe more) to support the vehicles. Why? Because solar systems are sized to supply what the home needs, not twice or three times current needs. Nobody is going to double their installed solar capacity just for the heck of it. That said, if the utilities didn't steal excess generation capacity as they do (they pay you 1/10 what they charge you per kWh) there might be real incentives to install additional capacity because you could actually make money with your installation. Not a simple problem.
