While that may be true - I can invest in home solar and have zero or near zero electricity costs at reasonable prices with a 5 to 7 year payback period. Near me solar farms run at a profit here in England, and yet I don't believe any nuclear power plant has run at a profit without government assistance, or subsidies, and none are yet expected to fund their own decommissioning and clean up - society will bear these costs.
Large scale solar are actually large scale gas plants.
Since there is no way to store electricity large scale and solar energy is unreliable then they depend on gas turbines to work.
