This work conducts a thorough analysis and a practical experiment on the DC load management capability of household photovoltaic systems. This study was set up to investigate the capability of DC load management to improve energy efficiency and self-sufficiency within residential contexts that are equipped with a photovoltaic system. A simulated model of a domestic photovoltaic system was prepared to present the patterns of solar energy generation, household energy consumption, and resulting energy balance over a time span of 24 hours. Different load management approaches were addressed, such as load shifting or using smart controllers that improve system performance. In general, it was concluded that the application of efficient DC load control can provide a reasonable energy surplus and reduce electrical grid consumption, hence increasing the sustainability of a domestic energy system. This report describes concepts for better DC load control and provides paths for further research, with emphasis on the implications of future smart home technology. (This refers to an hourly simulation representing one full daily operating cycle of the proposed PV system.)............... Keywords:............ Photovoltaic solar power system
