I think that’s what they called a First Generation generator.
The ones in use now will actually use sunlight to melt salt (than then is used to generate steam) rather than directly generating the steam which has way more capacity to store heat, so they have a solar conversion efficiency of between 38% and 44%, plus the molten salt can keep on being used to generate steam during the night until it cools down enough.
