DEVELOPMENT OF BOX–TYPE SOLAR COOKER FROM LOCALLY SOURCED MATERIALS

In this study, a solar box-type cooker was developed using locally available materials with the aim of investigating the thermal performance of the constructed solar cooker using standard test procedure. Several tests were conducted on the constructed cookers under Jal ingo (Nigeria) prevailing weather conditions during December 2021. The thermal performance of the solar cooker revealed that it attained a maximum average temperature of 77.1 °C for boiling test and 67.7°C for cooking test. Also, the results of the thermal efficiency for the constructed cooker during boiling test and cooking test were maximum at 9.00 hour (73.01%) and 15.30 hour (95.54%) respectively while cooking power during boiling test and cooking test were maximum at 13.30 hour with values of 0.472 and 0.83J respectively. However, it can be concluded that the use of solar energy in cooking is capable of protecting the environment and reducing health risks
