The only thing more expensive than a nuclear reactor is a battery bank of the same capacity.
Grid-tied batteries are now about $300/kWh. Capitalized over 25 years, that adds 3.3 cents to peak (11AM) solar prices, which themselves can go negative at times (duck curve in action), and overall are 3-4 cents per kWh.
Nuclear (new) portends to cost between 7 and 20 cents per kWh according to Wikipedia.
Downvote me if you must, but the numbers are right there. Nuclear may have been the best option for a time, but that time has passed and is not coming back.
For everyone else: The average solar panel cost is $3–$5 per watt or $15000–$20000 for a typical 5 kW system
A visit to sunelec.com or santansolar.com yields a litany of panels for sale well under $1/W. Half the offerings on Amazon are below $1/W as well.
As such, nowadays you should be paying no more than $10k for a 5kW system.

"How are we going to come up with $120,000?!"
