Abstract: In recent years, the introduction of photovoltaics (PVs) has been expanding in houses, but the instability of power supply and demand balance due to fluctuations in the amount of power generation has become a problem. Therefore, in this study, we proposed a system that combines PV, fuel cell (FC) and battery (BT), and conducted a case study of annual energy simulation in a house. As a result, the introduction of the proposed system increased the electricity self-sufficiency rate, reduced CO2 emissions and running costs, so the effectiveness of this system was shown.
