PROBLEM TO BE SOLVED: To provide a solar system for simultaneously supplying electric power, cold and heat and hot water in a process of forming low pressure gas by the adiabatic expansion of a high temperature supercritical pressure fluid, and forming a heat cycle for liquefaction performed following cooling of the low pressure gas by forming the high temperature supercritical pressure fluid by solar heat by using a low boiling point hydraulic fluid of a liquid, supercritical, near-supercritical, and undercritical state. SOLUTION: This solar system is composed of a pump-up part 11 for forming a liquefied working fluid as a supercritical pressure fluid, an evaporator 10 for forming a supercritical fluid as the high temperature supercritical pressure fluid by the solar heat, an expansion turbine 12 for forming the low pressure gas by adiabatically expanding the high temperature supercritical pressure fluid, and generating electric power, and a heat recovery unit 13 for recovering heat from the low pressure gas, and forming the working fluid of a liquid, supercritical, near-supercritical, and undercritical state.
