Ever stop and think that maybe it's because solar PV is FAR superior to other options with regards to efficacy? Do you have a carbon-free alternative that can even come close? My PV system is going to deliver ~35kWh today. Using heat pumps I can turn that into >100kWh to heat my home. That's equivalent to ~3 therms of natural gas or ~3 gallons of heating oil. From a single day in December. Do you have another alternative that even comes close? The lifetime cost of that ~35kWh is about $1. So combined with efficient heat pump heating I'm getting the equivalent of ~$0.33 per gallon of heating oil or therm. Is there anything else that can even come close to that?
And it's not like any of this is rare, elaborate or expensive. Home Depot sells heat pump water heaters for ~$1500. You can get a Mr Cool heat pump online that works great for ~$2k. Using fossil fuels is a choice. Make smarter choices....
Again, its about having a backup plan. You don't provide a long term backup plan. Its no better than my backup plan.
PA we have things called Clouds, Snow, and less sun in winter. I can guarantee it will run out of power without adequate battery backup which costs $$$$. Then add an electric car? I think having a system to back up the solar is a great idea, since I have a 85 mile commute. I actually would like to make it to work everyday to pay for my solar array and electric vehicle when i get them.
I don't know where Eunice is located, but it sound like a place everyone should live. Where the buffalo roam, the solar panels have 24hr sun, the electric cars are always charged, and endless cash to buy all of the "carbon neutral" items you desire.

Financially
Its a lot harder for me to justify a system when 1 pay .11 per kwh and 1/3 of my bill is service fee. My ROI is a lot longer than someone that pays .2 per kwh. There is a lot more to life than Carbon Credits. There is peace of mind in not having debt. I only have a house payment. I am not going into debt again to make "smarter choices" that are not necessary for my existence nor the existence of future generations. I will make my positive environmental impact with the resources I have available. Eventually I will have more green energy in my home.
I will keep my 20yr old paid for, still working cars. that way they don't got to the land fill, and recycler. No point in replacing them with a brand new EV right now.
