PURPOSE:To improve the efficiency of the cycle of sea temperature difference power generation by pumping-up the hot surface sea-water and forming the sea water having a relatively high temperature by a solar heat collector and evaporating working medium in an evaporator by said sea water and operating a turbine by said vapor. CONSTITUTION:The hot surface sea-water is pumped-up and sent into an evaporator 3 by a pump 2, and the thermal medium 4 having a low boiling point is formed into the steam having a high temperature and a high pressure through heat exchange, and said vapor is sent into a turbine 5, in which work is performed and a generator 6 is driven. The vapor having a low pressure which is sent from the turbine 5 is introduced into a condenser 7, and cooled, condensed, and liquefied by the cold sea water 8 in a deep layer, and the formed liquid is returned into the evaporator 3 by a circulating pump 9. In such a generation set which utilizes the sea temperature difference, a solar heat collector 20 is installed onto the downstream side of the evaporator 3 in a hot sea-water line or in a working medium line. Said heat collector 20 is preferably installed on the sandy beach on land, and the sea water and the working medium which passes through the heat absorbing pipe in the heat collector 20 can be heated efficiently.
