AB Funnel type solar cookers are simple and effective. Most of them rely on a multifaceted reflector to concentratesolar radiation on a cooking pot that is placed inside a transparent enclosure to create a greenhouse effect. Theanalysis of the resulting optical system is a complex task, as multiple reflections occur. The overall performanceof funnel solar cookers is strongly affected by their optical efficiency. There is a lack of information in academicliterature about this important research topic. This work aims to fill this gap presenting an optical performanceanalysis of a funnel solar cooker with only azimuthal sun tracking. Open-source numerical ray-tracing softwareSoltrace is used to investigate relevant characteristics such as the intercept factor, optical efficiency, dependencyon incidence angle, performance of each reflecting surface and irradiation density flux distribution on differentsurfaces of the cooking pot. Some important results for beam radiation at normal incidence are the interceptfactor, determined to be 0.664, and the optical efficiency with realistic optical properties, that turned out tobe 0.370. When the incidence of solar beam radiation is not normal, optical efficiency remains above 90% ofits normal incidence value, if the alignment errors are less than 10◦.
