Solar cooker is important in presenting an alternative energy source for cooking but the major drawback is the time spent outside to monitor the food during the cooking process, because most solar cookers are designed for external use. This study aims to reduce the cost of purchasing fuels, drastic reduction in the carbon emission to enhance cleaner and safer environment for healthy living and the materials of construction are readily available hence the need to develop an affordable building integrated hybrid solar cooker. The test carried out included the stagnation and water heating test, then the figures of merit were determined.  Controlled cooking test was done by cooking five pieces of egg for 90 minutes, and the cooking of 820 g of rice at 120 minutes. The maximum stagnation temperature for evaluation reached by the absorber plate of the indoor box cooker is 158℃ while the corresponding maximum pot temperature is 167.4. The maximum temperature attained by heating 1kg of water is 105.3, the maximum temperature attained by heating 1.5 kg of water is 101.6 and the maximum temperature attained by heating 2kg of water is 100.4. The maximum standardized cooking power attained   during evaluation was 392W. The first figure of merit at stagnation temperature for six days was 0.17, 0.18, 0.10, 0.081, 0.091 and 0.094 respectively and the second figure of merit at water temperature for six days was 0.44. 0.50, 0.35, 0.21, 0.28 and 0.37 respectively.
