Abstract
In this paper we consider the system to cover all energy by solar cells. System is composed of solar cells, PEFC, water electrolyzer, and heat pump. In this paper, we developed a analysis program by genetic algorithm. And, revealed the capacity of the equipment and two types of operational methods. A result of the analysis, equipment capacity needed in the first method of operating, solar cells is 250m2, PEFC is 8.1kW, water electrolyzer is 22.1kW, heat pump is 14.4kW, amount of hydrogen storage is 106.6kWh, amount of heat storage is 10.2kWh. In addition, equipment capacity needed in the second method of operating, solar cells is 300m2, PEFC is 4.7kW, water electrolyzer is 30.1kW, heat pump is 8.5kW, amount of hydrogen storage is 84.9kWh, amount of heat storage is 21.5kWh. To consider the cost of equipment as the next step.
