You shouldn't be installing a 30KW system, but it's entirely reasonable for utilities to deploy 30KW of utility-scale solar on your behalf. According to 2021Q1 numbers that's $23-26K of capital investment. Plus I imagine with some logistical effort the utilities can deliver it to wherever your car is parked during the day, rather than bothering with a second set of batteries. Not sure why we're comparing utility-scale nuclear to artisanal home solar power.
