A solar box cooker (SBC) has been developed for the thermal performance evaluation by operating it on a low cost thermal storage. For this, a mixture of sand and granular carbon has been prepared and tested for an optimum ratio under a solar collector. After testing, the ratio of 4:6 (sand: carbon) has been observed to maintain a high temperature range with long term heat storage. This mixture has been used as thermal heat storage inside the SBC. The experimentation procedure has been conducted under climatic conditions of Moradabad, India. Results indicated that the first Figure of merit (F1) was 0.13 m2°C /W, second Figure of merit (F2) was 0.44 m2°C /W, thermal efficiency was estimated to be 37.1%, cooking power was estimated as 44.81% and overall heat loss coefficient was 3.01 W/m2°C. The system was found feasible for cooking during the off sunshine conditions.
