But solar isn't built like nuclear. Solar involves parallel exploration of device designs at very small scale, installed with massive redundancy and resilience. Many billions of PV cells have been manufactured. The real cost decline driver is manufacturing automation. Nuclear, even SMRs, have orders of magnitude coarser granularity.
If you want "hot rocks", it's probably much cheaper to just resistively heat them with cheap solar (you don't even need inverters). This could store energy over many months and, pushed to its cost reduction limits this promises to be the final nail in the coffin for any dreams of a nuclear revival.
