ABSTRACT
Experimental water heating studies were performed to study the performance of inclined box and flat box solar cookers under the solar insolation conditions of Kumasi from May to July 2016, 10:00 to 14:00. The local solar insolation and average temperature profiles for the water and ambient were determined for the duration of study. Analytical methods of the ASAE S580.1 NOV2013 test standard were employed to estimate the interval cooking power and standardized cooking power of both solar cookers. The cooking power and efficiency in heating water to the point of maximum temperature were also estimated for both cookers. Generally, the inclined box cooker performed better than the flat box cooker by generating a relatively higher peak water temperature, higher cooking power, and higher efficiency. Further studies have been recommended to improve the design of the cookers and analyze the effect of insulation on the performance of the new cookers under similar solar insolation conditions.
