<p>In recent years, the transport sector has experienced substantial technological reforms driven by rising environmental concerns and the pressing need for energy security in the face of diminishing petroleum resources. As the global pursuit of sustainability intensifies, attention has increasingly turned toward the advancement of green mobility solutions. Among these, the Solar Electric Vehicle (SEV) has emerged as a compelling innovation, blending renewable energy integration with automotive progress. However, the operational effectiveness of SEVs is intricately tied to external factors such as solar irradiation, temperature, weather variability, and geographic context. This paper proposes a probabilistic approach to assess the operational effectiveness of an SEV, explicitly incorporating the intermittency of solar generation, with and without supplementary grid support. The model, developed within Markov framework, links the dynamic characteristics of onboard photovoltaic generation with charging infrastructure behaviour. The study provides deeper insights into SEV’s effectiveness under realistic operating conditions, offering a foundation for advancing the design, deployment, and optimization of solar-driven mobility systems.</p>
