This thesis explores the optimization of residential energy systems in Belgian households, focusing on the integration of photovoltaic systems with various production assets. The study provides a comprehensive analysis of energy consumption patterns, residential photovoltaic potential, and energy pricing mechanisms in Belgium. A linear optimization model has been developed as a practical tool for users, guiding them to maximize the economic benefits of their solar panel installations. The model is applied to two case studies, each demonstrating the value of combining different household energy assets in achieving optimal energy efficiency and cost savings. In the first case, the results indicate that the strategy to adopt is based on the annual balance between grid injection and consumption, without necessitating immediate self-consumption. When the household’s photovoltaic production exceeds its consumption, it is beneficial to use an electric resistance heater, although the impact of this strategy is limited. If the household produces 1.5 times more energy than it consumes, installing a heat pump becomes an advantageous option, enhancing both efficiency and economic returns. In the second case, immediate self-consumption becomes essential, highlighting the need to adapt energy strategies to the specific solar production and consumption patterns of each household. When solar production surpasses consumption, it is beneficial to utilize the excess energy with an electric resistance heater, which is managed intelligently through a hot water tank. However, in this scenario, investing in a heat pump does not provide significant economic benefits. These findings highlight the necessity of a customized approach to energy management, aligning strategies with the unique production and consumption dynamics of each household. This tailored approach enables households to maximize economic savings and environmental benefits, supporting a more sustainable and cost-efficient energy future.Home energy managementHybrid heating systemsEnergy optimizationPhotovoltaic integrationtext::thesis::master thesisthesis:49216
