192 challenges became particularly evident in Ukraine after the outbreak of armed conflict with Russia in 2022, which led to widespread destruction of energy infrastructure. According to the International Energy Agency (IEA), more than half of the country's electricity and heat generation capacity was lost between 2022 and 2023, and a further escalation in 2024 reduced available resources to a third of pre- war levels [3]. In response to these challenges, international experts and scientists emphasize the need for a radical transformation of Ukraine's energy system, prioritizing rapid recovery, enhanced resilience, reduced dependence on imported fossil fuels, and mitigation of environmental impacts. In this context, renewable energy, particularly solar energy, is regarded as one of the most promising technologies capable of simultaneous addressing environmental and security concerns. The importance of decentralized generation as a key mechanism for strengthening energy resilience is particularly emphasized, as supported by both international policy recommendations and national strategies. Decentralized renewable energy sources make it possible to reduce the load on centralized grids, minimize transmission losses, and ensure local power supply even when transmission infrastructure is damaged. Solar photovoltaic generation, especially in the form of rooftop PV systems, is a leading decentralization technology due to its scalability and the ability to be deployed directly at the point of consumption. It enables rapid generation deployment, flexible integration, and the ability to combine with energy storage systems, which is particularly important for the Ukrainian context. The potential for the deployment of rooftop photovoltaic systems (RTPV) in Ukraine is already showing significant growth: by early 2024, the total installed capacity of consumer-side solar panels have reached approximately 1.5 GW, with state programs prioritizing RTPV development within the non-residential sector. The drivers of this dynamic extend beyond environmental considerations to include critical security concerns, as decentralization has become a strategic response to threats against energy supply continuity caused by military actions.
