For apartments with 30 or more households, the government is implementing a zero-energybuilding mandate from 2023 in the public sector and 2024 in the private sector. Many localgovernments are promoting mini-photovoltaic (PV) system supply support projects that can beinstalled on apartment balconies. An apartment mini-PV system is a concept that installs a PVmodule on a balcony and directly supplies the power from the PV to the household outletthrough a plug. In this study, we analyzed real-time power consumption patterns forapproximately one year for apartments in the Seoul area and analyzed the amount of powergenerated by mini-PV systems installed on balconies. The power consumption pattern byhousehold and the amount of PV power on the balcony showed significant differences owing tothe influence of life patterns of the residents, PV installation capacity, and installationenvironment. However, power consumption was the highest during the evening and summer,and balcony PV power was highest during spring and autumn. In addition, a large amount ofsurplus power is generated during the PV generation. The balcony photovoltaic systemcontributes to a household electricity energy self-sufficiency rate of 26%, on average, for fourhouseholds by electricity production. |
