The working principle and status quo of research for five main kinds of solar energy thermal power generation system

namely tower type

trouph type

dish type

solar energy hot gas flow type

and solar energy pool

have been presented.Comparison of advantages and disadvantages for above-mentioned solar energy thermal power generation systems shows that as in the following:the tower type system has high light concentration ratio

large capacity of system

and high efficiency

but expenses being very high;the trough type system has simple structure

but the light concentration ratio being small

and the working temperature in the system being lower;the dish type system has large light concentration ratio

high system efficiency

compact structure

and convenience in installation

but large difficulty in techique of its key part i.e.the Sterlin engine;the solar energy hot gas flow power generation and the solar energy pool

as well as the downward reflecting type solar energy thermal power generation etc.

each has its own superiority in technical aspects.
