I don’t get this.
Doesn’t solar have DC to AC converters that maintain a constant desired frequency? And why would one solar installation going down cause the rest of them to not keep producing electricity at the set frequency?
By law or tariff, all private solar must cease output should a grid glitch occur. Law says 5 minute lockout.

Probably because there is no peak handling demand built into the system. I’m not familiar with solar plants, but something like a large battery bank that could soak up peak demands.
This of course could be impractical or uneconomic.
Yes the solar farms do have DC/AC converters.
But they will automatically follow the grid frequency.
When a large solar farm trips off line the load it was carrying will drag down the rotating generators that govern the frequency of the grid. (slow down the generators)
If the rotating generators do not have the capacity to increase power to compensate for the slowing, frequency drops.
Spain foolishly has decommissioned coal plants that could have been spinning reserve that could have been spun up to recover the grid
