Solar cooking is considered an eco-friendly technology and an appropriate solution for cooking purposes, particularly in Saharan areas with abundant insolation. This work discusses the performance and behavior of a box solar cooker (BSC) that tested experimentally in three modes: solar mode, and in addition, was preheated using a resistive heater specifically in two modes electric, and solar-electric. Comparative tests were performed and temperatures were measured during the winter of January 2024 under the climatic of the Ghardaia region. The results of the experiments indicate that the maximum temperature of absorber tray reached in solar, electric and solar-electric mode was 124.428 ℃, 108 ℃, and 133, 68 ℃ and in addition, that the figures of merit F1, and F2, were obtained as 0.16 m2 ℃/w, 0.476, and efficiency was estimated by 40% and 42.7% respectively; in the case of using solar and solar electric mode. It also was noticed that cooking time can be reduced considerably when using the solar-electric mode.
