A small review on the box type solar cooker applications and its designs given here. Two designs of cookers were tested. The first type has a painted black base and second type has a pained black with coal. These designs were examined under two modes of operations: at fixed position and on tracking system. The cooker at a fixed position had recorded thermal efficiencies ranging from 25.2 % to a sharp peak of 53.8% at the maximum solar intensity of the day around 12-13 pm with an average overall efficiency around 32.3%. Whereas, cooker with black coal pained installed on a sun tracking system gave higher water and pot temperatures, and thermal efficiency ranged from 28% to 62.1% with an average overall efficiency around 43.8 %. Cookers installed on sun tracking system had the advantage of maintaining a higher as well as closer range of thermal efficiencies through the daylight than the ones at fixed positions
