The thing about a coal, gas or nuclear plant is that they can't switch off as fast as solar. Solar can switch off in the span of a microsecond without much of an issue.
A coal/gas/nuclear plant might actually need the entire day to shut down operation to 0 kW output. And probably needs a day to get back to full operation. So in cases of negative prices, a solar energy producer can do the sensible thing and switch off while a plant operator will probably try to weather it.
