190 Under crisis conditions, particularly armed conflicts, natural disasters, or system failures, the efficiency of centralized energy systems is significantly reduced. The destruction of generating capacity and transmission grids leads to prolonged power outages, highlighting the need for decentralized solutions. This is why the development of renewable energy is increasingly considered not only through the prism of environmental feasibility but also as a tool for enhancing energy resilience and local-level autonomy. Among all renewable energy sources, solar energy stands out due to its high scalability, relative ease of integration, and the ability to be deployed close to the consumer. Photovoltaic systems can operate both in centralized power plants and as distributed installations on buildings and infrastructure facilities. This versatility makes solar energy one of the most promising areas for the development of decentralized generation, especially in urban and suburban areas. Solar energy gains particular significance in the form of rooftop photovoltaic systems, which enable the integration of electricity production into existing built environments without imposing additional pressure on land resources. The deployment of such systems creates prerequisites for a transition from centralized grids to localized energy solutions capable of operating under instability with limited access to main infrastructure. In this specific context, a detailed analysis of the potential of rooftop solar generation is highly pertinent, as it represents a key element in the decentralization of renewable energy under crisis conditions. The destruction of centralized energy infrastructure under crisis conditions highlights the need to rethink the traditional energy supply model. The transition from hierarchically organized grids to local, decentralized solutions is considered as a key strategy for enhancing the resilience of energy systems. In this context, rooftop photovoltaic systems are an effective tool for energy system transformation, combining decarbonization goals with increased reliability of local energy supply. For Ukraine, this transformation is particularly important given the extensive damage to generation and heat supply facilities, which constrain the operation of centralized grids. Local renewable generation can reduce consumers' dependence on
