If one were willing to run some numbers. Californians drive 340 billion miles a year. If that were all EV's then they would consume 85 billion kwh/year. Solar insolation is about 2000 hours a year. So you would need 42.5 GW of solar. With say 30 million cars that would be 1500W per car. Check, average car drives 35 miles a day. So needs 8.75 kwh. 6 hours of sunlight so you'd need 1460 watts or solar. That's $1500 worth of solar per car. Set and match. Totally totally doable.
