PURPOSE:To improve the operating efficiency of a plant by a method wherein hot-water is produced when the sunshine is low while steam is generated when the sunshine is normal, in order to supply them to a load side. CONSTITUTION:Water is circulated in the route of a low temperature valve 2, a heat exchanger 3 and a mixer 4 when the sunshine is low by opening the low temperature valve 2 and closing a high temperature valve 13. Supplementing water 6 receives heat in the heat exchanger 3 and rises and evaporates flon in a flon generator 7 while a turbine 10 is driven by the vapor of flon to generate electricity. When the sunshine is normal, the high temperature valve 13 is opened, the low temperature valve 2 is closed and the water is circulated in the route of first and second steam generators 14, 15, a three-way valve 16 and the mixer 4 while steam is supplied to the heat load 18 and an electricity generating device 19, thereafter, the heat medium is introduced into the heat exchanger 3.

Recently, as the depletion of petroleum energy becomes more familiar, the use of solar thermal energy as an alternative energy source to petroleum has been attracting attention. However, when receiving solar thermal energy on the earth's surface, the input cannot be said to be constant. The amount of solar thermal energy obtained from morning to evening varies depending on the time of day, and is also greatly influenced by the season and weather conditions.

Therefore, in order to stably supply thermal energy to loads that require high temperatures, it is necessary to install equipment that increases the concentration of sunlight, which is costly and is not sufficient when solar radiation is low. Since a high temperature cannot be obtained, the operating rate decreases, making it even more uneconomical. On the other hand, for low-temperature loads, equipment can be made cheaper, but even in conditions where high temperatures are easy to obtain, such as on a clear day, the energy that can be used at high temperatures is used. Natural energy has no choice but to be used at low temperatures, which is an unsatisfactory level of utilization in terms of effective use of natural energy.
