Each nuclear plant is practically a new adventure, and recursively so. It’s specialized work and the people who learn to build one properly don’t travel the world consulting on them, except perhaps at the management and design levels. Welders aren’t.
replyMeanwhile once you’ve installed 10% of a solar project, the rest of the project is almost exactly the same, and you can ramp up or ramp down the size of the final build as you go and capital either becomes constrained or part of the build goes online and starts subsidizing the rest. Your experts have journeymen under them that can start taking on more work allowing the throughput to increase.
How Big Projects Get Done talks about how roads, solar and wind all have this property, and most special projects don’t, which leads to either massive cost overruns or dead projects.
Solar install is also easier and requires less exactitude, so training is faster and easier. Lose 1% of the modules in a PV field and your output is down slightly and temporarily. Screw up 1% of the welds in a nuclear plant and you're in massive trouble.
