From view point of thermodynamic system

three main kinds of power generation technology using solar energy have been presented

i.e.tough-type system

tower-type system

and disk-type system

which are already being in operation on the world.Combined with typical power station

the main parameters

such as the efficiency of power generation

the technical cost of each system

have been analysed

the advantages and insufficiencies of different technologies being pointed out.The analysis shows that the tough-type system is the most matured technology in the three said technologies

occupying the largest capcity ratio

appearing good usefullness;through further icreasing the scale

the tough-type system and disk-type system can reduce operation cost in the future

the efficiency will be enhanced.
