Funnel type solar cookers rely on a multifaceted reflector to concentrate solar radiation on a cooking pot that is placed inside a transparent enclosure to create a greenhouse effect. This work aims to analyze the optical performance of this type of solar cooker using raytracing techniques. The open source Soltrace software tool is used to create an optical model of a solar funnel cooker. Numerous raytracing simulations are conducted in order to complete a parametric analysis of the optical performance against a set of influence variables, such as the elevation angle, sun tracking errors, optical quality of the different elements involved ( reflectors, greenhouse, cooking pot), etc.Universidad de MΓ‘laga.
