Investigation and research on solar energy utilization system (solar thermal power generation system); 1979 nendo taiyo energy riyo system chosa kenkyu seika hokokusho. Taiyonetsu hatsuden system %XAn investigation and research were conducted on the operation method of various solar thermal power generation systems and on the evaluation of the rating and cost performance; in the environmental test method for the equipment, the examination was continued for the test method and evaluation method concerning the absorbing surface and transmitting film; in the heat storing technology, an investigative research was done on the optimum heat storing method and energy conversion method suitable for the operation of the thermal power generation system, as well as performing, as an objective, a computer simulation on the total system with the purpose of clarifying the heat storing capacity. The results in the year were as follows. The operation method for solar thermal power generation was examined, as were the energy analysis, evaluation method of 1 MW pilot plant, the optimum utilization system of solar energy in the long run including its application, and technological economical problems to be solved for the next large solar thermal power generating plant. A discussion was carried out on the endurance test of the selective absorbing surface and transmitting film and on the durability of the reflection mirror. Evaluation and examination were made on the various materials of the 1 MW pilot plant. A review was done on various heat accumulating devices for solar thermal generation, mathematical thermal characteristics of heat accumulating devices, and future energy storing methods and problems.
