Abstract: In this study, the annual electricity consumption of nine real houses from different cities in Türkiye was recorded on a monthly basis. The feasibility of meeting the electrical energy needs of houses with hydrogen and supplying the energy required for hydrogen production using solar panels is examined. The annual electricity consumption of the houses was normalized based on house size. The solar panel area for hydrogen production needed for these houses was defined. Additionally, it was calculated that the average volumetric amount of hydrogen produced per hour during peak sun hours in the investigated cities was 1 m 3 /h. This approach reduced the solar panel area for hydrogen production by a factor of 1.7.
